Chapters of the mobile phone guide

Smartphones

Smartphones have been a huge phenomenon of the last few years. They offer a large, yet reasonably sized touchscreen and the option to choose the applications you want to use, due to a pre-installed operating system (OS). They also offer an integrated camera that goes beyond any camera in a classic phone, a music player, internet access and other life-enhancing features.

Smartphone parameters

Screen

When choosing your phone, think about a screen size that is be optimal for you. If you only use a phone to make calls and send messages, a smaller screen is enough. If you take photos and like browsing through the images you too, we recommend a high resolution and screen diagonal. A smartphone standard today is a Full HD resolution (1920 × 1080) on a 5" to 6" screen.

Usual smartphone screen sizes

  • 4" to 4.4" - a very compact phone, ideal for users requiring a minimalist touch-screen smartphone.

  • 4.5" to 4.9" - a balanced display surface size and compact size ratio that can be handled with one hand.

  • 5" to 5.4" - the most common size nowadays, popular for multimedia, movie-watching, gaming, and surfing the internet.

  • 5.5" to 6" - a device between a phone and a tablet (phablet) that you can barely fit in your pocket. The size is perfect for work.

  • 6" and more - devices bewteen smartphones and tablets for those who need more space for multimedia, games and documents instead of a compact size.

Screen technology

OLED screens are the best on the market. They are divided into two categories based on the matrices used.

  • AMOLED - they contain an active matrix. They differ from other imaging technologies in their very loyal black color rendering, which gives them unrivaled contrast. This includes wide viewing angles, low battery usage and low response.

  • P-OLED - passive matrix screens. There are simpler and cheaper designs. They are used especially in smart watches and small displays.

LCD screens generally have a higher power consumption than OLED screens. However, their design is much cheaper, and therefore we see LCD screens in cheaper models.

  • Super LCD - They are popular for their bright colour display and low power consumption. The minimum distance between the screen itself and the cover glass is a great advantage.

  • IPS - A very authentic display of a wide range of colours with the best viewing angles. It is the most widespread technology among mobile phones and can be found on most mid-range models.

  • TN - An older LCD technology, widely used especially for desktop monitors. They are inexpensive to produce, have high brightness, and are less emanding on battery life. However, the poor observation angles can be a disadvantages. We can find them mainly in older and cheaper phones and tablets.

The most common resolution

 
 Screen resolutionScreen resolution size
HD1 280 × 720px
Full HD1 920 × 1 080px
WQHD2 560 × 1 440px
4K3 840 × 2 160px

Operating memory RAM 

Every smartphone has its own memory. When choosing a phone, it is one of the most important parameters to consider. The larger the memory size, the faster and easier will it be to handle more operations at a time.

How many GB of memory do I need?

  • 1GB - we find it in the cheapest and older smartphones. It is usually not enough for modern applications and the system gets stuck and does not respond when the load is more demanding.

  • 2 - 3GB - this is now considered a standard. 2 to 3GB of memory are enough for browsing, listening to songs, and playing games.

  • 4 or more - found in the best phones. Usually, you do not use the full amount of memory, but it is a good safeguard for the future, as the demands of applications are constantly increasing.

Processor

Processor cores

The most important part of the processor that is responsible for all computational operations. In smartphones, the number of cores usually ranges from 4 to 8, the more cores the better. Multiple cores work better between each other to shorten the processing time.

Processor frequency (clock)

Frequency indicates the number of instructions the processor can perform in 1 second. It is indicated in GHz. Higher frequencies increase the CPU performance. Common frequency values ​​range from 1.6GHz to 2GHz.

What processor do I need?

For the Android operating system today, a quad-core to octa-core processor at 1.5GHz is considered to be a standard. For Apple iPhones with iOS, you do not have to choose from performance-based options, as each model is designed to be swift and smooth. The Windows Phone has minimal demands, therefore a processor that is three times weaker than an Android's one will be enough. 

Processor model specification

This is basically only indication that can help you predict the performance of your phone after searching for reviews and benchmarks. For example, a modern quad-core chip may be more powerful than an outdated eight-core.

The best knowm manufacturers


Qualcomm
Their processors and graphics accelerators are particularly praised for their multitasking capability and gaming performance. The company has been manufacturing processors since 2005 and has gone through a long history of mobile engineering. Their Snapdragon processors are also used on flagships of the largest manufacturers, such as Google Pixel, Xiaomi Mi, or some of the Samsung Galaxy S model variants.

  • Snapdragon - a CPU unit performance class specification. The series are marked with numbers: S200, S400, S600, S800. The first number marks the processor range and the second the processor model. The higher the number, the more powerful the processor. A graphic accelerator is also part of the processor.

  • Adreno - graphic accelerators that have a similar function to graphic cards in notebooks and computer desktops.


MediaTek
The Taiwanese processor maker MediaTek is one of Qualcomm's main competitors. In its portfolio, it has everything through low-cost processors, mid-range chips, futuristic X-series - which reaches up to 3GHz. It boasts plenty of original features such as the patented MiraVision. These processors are very popular with Chinese manufacturers - most notably Xiaomi and Meizu.

  • Helio - the most recent pride of this company. The MediaTek Helio processors combine the best of all previous generations. The manufacturer calls it the processor of the future.


Samsung
The Korean electronics company has definitely not stayed behind and is making the processors that are used in their best mobile phones. It often mixes them with Qualcomm's processors, depending on the market the phone is made for.

  • Exynos - a key range of octa-core processors by Samsung. Due to the advanced graphics chip, they are capable of being used for playing 3D games and processing a 4k UHD resolution.


Apple
Apple does not make nor design its own processors, but hires different companies, especially Samsung and TSMC.

  • Apple A - processor specification in phones and tablets. The iPhone 7 uses a quad-core A10 model with a 2.4GHz frequencie. It has a built-in graphics unit that improves the graphics performance of the phone by as much as 50% compared to previous models.


HiSilicon
A Chinese company owned by Huawei. It is the largest printed circuit manufacturer on the Chinese market, and has a great background for the development of new technologies. Unlike other Asian manufacturers, it does not increase performance by the number of computational cores, but improves the core itself.

  • Kirin 900 - the latest range mobile processors used almost exclusively in Huawei and Honor smartphones and tablets.


nVidia
A well-known graphics card player started manufacturing mobile processors a few years ago and is certainly not behind the competition. nVidia processors excel primarily due to their performance in games. The state-of-the-art Tegra X1 is a quad-core chipset with a 256-pixel graphics unit and is therefore used in the Nvidia SHIELD Android TV portable game console. nVidia processors are ideal for all players.

  • Tegra K1 - a processor used in many different mobile phones, or the Nvidia SHIELD tablet that can be used for computer games such as the Half-Life or the Knights of the Old Rebublic.

Battery

Battery life is reported in units of mAh (milliampere hour). The higher the number, the greater the capacity. When selecting, consider other aspects that may affect the discharge speed, especially the size of the screen, the CPU performance and the use of data functions. In order to compare the battery life between individual phones as much as possible, the so-called standby time is indicated. This is tested in a laboratory and it is definitely not the real endurance. It is the maximum time that the phone will last for a single charge.

Many phones support the fast charging function. The technology name differs depending on the manufacturer - sometimes you can come across the concept of Rapid Charge, Pump Express, Quick Charge and more. The most common is Qualcomm's Quick Charge 2.0 technology, which can charge the phone's battery from 0 to 60% in about 30 minutes. At the end of 2015, an upgraded version of Quick Charge 3.0 was introduced to charge the phone from 0 to 80% in about 35 minutes.

Camera

Often the most important factor when choosing a mobile phone device is the built-in camera. Whether it's nature, portraits, food, or a self-image, the best mobile cameras are replacing, comparing them with large, compact ones.

Rear/Front Camera

Almost every mobile phone, whether a smartphone or regular keypad phone, is equipped with a rear camera. It generally has a higher resolution, higher luminosity and wider lens, for nature and scene images.

During the last few years, smartphones have also developed a selfie photography trend. The front camera is used for that and also for taking pictures for social media accounts.

Dual camera

It can accelerate focus, increase luminosity, change the focus area, capture the image, and adjust sharpness depth in different ways. A dual camera has many different capabilities and features that depend on specific phone models.

Distinction

This is number of pixels that the resulting photo will contain. It's definitely not a factor that should determine the quality of the camera because the quality is primarily determined by the size of the sensor chip, and there is almost no difference between 14-28Mpx. Even the best manufacturers are more likely to use lower resolution cameras - iPhone 8 (12Mpx + 7Mpx), Galaxy S8 (12Mpx + 8Mpx).

Higher resolution is ideal for large image sizes, but the size of the sensor will be limited and the image quality will be lower in comparison to reflex cameras.

Luminance and aperture

The main camera parameter is not only a megapixel (MPx), but also the luminance. This is indicated by the letter "f". The number behind it indicates the loss of light when passing through the lens. The lower the number, the better the device can handle the light insufficience, which is necessary in order to achieve sharp shots, not only in dim light. Greater luminosity can also create a beautiful blurred background that we all love so much. The ideal smartphone aperture size is around f/2 to f/2.4. The best devices offer a luminance of f/1.7

Video

Mobile phone cameras can also record high-definition videos, often with different features, such as slow-motion or a time lapse video. Most phones record in a Full HD resolution, with the best models handling even 4K.

HDR and scene Modes

Mobile phone cameras work more automatically than manually and feature many different modes for all kinds of occasions.

HDR is a feature that has always been used in photography and is has now found its place in digital photography. It is a combination of photographs of various exposures to produce a high-contrast image.

The panorama mode allows you to capture very wide photos, i.e., the entire view from a tower.

The portrait mode is designed for taking pictures of people, uses the smallest aperture and blurs the background.

Macro mode is used when taking pictures of small objects, such as flowers.

Stabilisation

Because you rarely use a tripod with a mobile phone camera, image stabilisation is an integral part of each camera. It is divided into two categories - Electronic (EIS) and Optical (OIS). Cheaper models have electronic stability that only increases the ISO sensitivity to achieve a shorter shutter speed. The resulting quality of a photo may be theoretically even worse than without applying software stabilisation. OIS, on the other hand, provides much better results, as it is built into the camera.

Autofocus

Any decent camera should support autofocus. Higher-quality phones accelerate short-range sharpening with laser, and detection auto focus (PDAF) for any other kind. The best devices use a combination of both methods. For iPhone, the PDAF variation is called Focus Pixels.

Connectivity and sensors

Connectivity

  • LTE/4G

Nowadays, no smartphone should be missing an LTE high-speed Internet support. Beware of some devices that support LTE, but they do not understand Czech frequencies. Most of the local LTE network is built at 800MHz. In our technical parameters, you will usually find whether or not the given device supports the "Czech" LTE.

  • GPS

Connecting to the Global Positioning System allows you to track your position on maps anywhere on Earth with the accuracy of several metres.

  • Galileo and GLONASS

A European and Russian satellite system similar to the american GPS. Galileo should be fully operational by 2019 and achieve more accuracy than GPS.

  • WiFi

Internet connection via WiFi wireless technology.

  • Bluetooth

Wireless communication with other devices, especially speakers and headphones. The higher the range, the faster the connection speed and the lower the power consumption.

  • NFC

A way of communication between two electronic devices. It serves for both data and information transmission. It is referred to as the technology of the future and is now used mainly as a substitute for payment cards. Although this technology is not very widespread in the Czech Republic, it is possible to pay for purchases in the United States or the United Kingdom using mobile phones applications such as Google Wallet. Just attach it like a contactless credit card.

  • Infraport

It is used to transmit data using infrared radiation. Today it is no longer used as it was replaced by Bluetooth and NFC. However, it still finds its use with a variety of electronics, such as televisions, air conditioners, home music players, etc.

  • Micro USB/USB-C/Lightning

Sockets designed for a data cable connection. The data cable is used to charge or connect the phone to the computer.

Micro USB - The most common connector type, especially for Android phones.

USB-C - A modern USB version, mostly for new smarphones.

Lightning - Exclusively for iPhones.

Sensors

  • Barometer

An atmospheric pressure meter. A very useful gadget for smartphones.

  • Light sensor

If you do not enjoy adjusting the screen brightness, the light sensor will do it for you, so you can see everything you want ion thr screen.

  • Motion sensor (accelerometer) and gyroscope

They monitor the movement and position of the phone. They are particularly used in the gaming industry, but they can also be useful helpers in everyday life - such as a mobile spirit level.

  • Magnetic compass

It is used to identify the worlds cardinal points through the Earth's magnetic field.

  • Sensor of proximity

A very important sensor for every smartphone. When the phone is too close to your face during a call, the screen locks to prevent unwanted contact and turning off the call.

Internal storage and memory cards

Especially for phones without a memory card slot, be careful and choose a slightly larger memory size option. Also, consider that the phone's operating system memory size is not included. If you buy a device with 16GB of memory, take into account that the average operating system occupies approximately 4-5GB of free space, leaving you 11-12GB for your data. In addition, the available storage for Android phones may vary between models and manufacturers, since each manufacturer pre-installs different apps in their phones and uses their own graphical superstructures.

The following memory size variants are offered on the market:

  • Up to 8GB - phones with only enough space for a few applications and a small amount of music.

  • 16GB - for modest users. The capacity can hold several apps and music albums.

  • 32GB - for dozens of applications and common usage. It is sufficient for most users.

  • 64GB - for dozens of apps, games or music albums, or several movies.

  • 128GB - can store hundreds of apps, games and dozens of movies. Suitable for intensive usage.

  • 256GB - can store dozens of movies, games and applications to satisfy even the most demanding users.

Materials

The material used to make your phone plays an important role in its appearance, durability and price .

  • Plastic - all-plastic phones are relatively fragile and are especially used for cheaper models. Plastic is also often used for camera lenses.

  • Aluminum - pricier premium phones are primarily constructed from aluminum alloys. For middle-class mobile phones, you can find a combination of aluminum and plastic or polycarbonate with a worked surface.

  • Glass - a material used especially for premium phones to design the back cover.

  • Ceramics - a hard material that is scratch-resistant, but frailer against the metal.

Useful features

Fingerprint sensor and retina scanner

If you are worried about the security of the information and files on your mobile phone, these features will take your security to the next level.

AI Assistant

A useful feature built into every operating system. Finds the closest restaurant to you, or makes a call after hearing only a few words. The AI iOS assistant is called Siri, Windows Mobile uses Cortana, and Google has simly named it Google Assistant.

Wireless charging

If you are fed up with entangled wires, think about choosing a phone with wireless charging.

Notification diode

The diode lights up in any colour according to the occasion you set up. This is definitely a useful smartphone element!

FM radio

Most mobile phones can use your headphones as a radio signal receiver. Tune in to your favorite station wherever you are!

QWERTY keypad

The entire keypad simplifies and speeds up typing on classic keypad phones. If you write a lot of messages per day and you are interested in a keypad phone, consider this feature!

Dual SIM

Telephones with the ability to use two SIM cards at one time are called Dual SIM. On one card you can have a voice tariff and a data card on the other, or you can use the services of two operators at the same time. A large number of phones allows the use of data services in only one of the SIM card slots. Dual SIM mobile phones are manufactured in both keypad and touch-screen versions.

Increased durability

You can expose telephones with increased resistance to moisture or dust without damaging them. The level of resistance is usually indicated by the degree of protection, e.g. IP65 or IP68. The first number indicates resistance to dust penetration, the other to water. You can immerse your IP67 phone into the water for half an hour at a maximum depth of one metre. The rain won't damage it either. The crash resistance required for outdoor and sport activities is judged best by the rubber bumpers on the body of the phone.

Frequently asked questions when choosing a camera phone

Is a camera with more megapixels better?

More megapixels do not necessarily mean a better image. The size of the camera sensor is important. Mobile phones usually have a sensor and more megapixels on a small screen can cause more noise. Upgrading the photo with the mobile phone software deletes minor details. Therefore, the best camera phones have 12-15 Mpix.

Which are the camera's parameters to focus on?

To assess the camera's quality of the phone, it is good to focus on the luminosity and optical image stabilisation. The luminosity represents the amount of light that falls on the sensor and the f/decimal number. The smaller the number, the more light falls on the sensor, which is particularly useful when staking pictures under dim lighting conditions, for example in the evening. Optical stabilisation is built directly into the optical system of the lens and is significantly more effective than software stabilisation. It reduces the camera shake when holding it in your hand, making the photographs unclear.

Is there a difference between smartphones and camera phones?

They are not. Camera phones are smartphones with a high-quality camera.

Frequently asked questions when choosing a virtual reality smartphone

Should I be interested in virtual reality at all?

If you are thinking about buying a new phone, it is certainly worth it to try virtual reality. The screen resolution is not as high that the virtual world would be identical to the real world, yet a visit to other worlds is an unusual experience. In virtual reality, you can play games, watch spatial videos where events happen around you, or view spherical photos that look great in VR.

Which screen diagonal is ideal for VR?

For virtual reality, the ideal phone diagonal is 5" or more. A larger diagonal means a larger field of view. However, with the screen diagonal increasing, the display's fineness decreases, therefore a larger display will not be as sharp. A larger display has a larger field of vision in the VR, but a lower fineness. A compromise is a diagonal of about 5.5".

How about the screen resolution?

For normal use, a Full HD resolution is sufficient on phones where nobody can really distinguish the individual pixel points. However, when the phone is inserted into the VR headset, the situation is different and the Full HD resolution is no longer ideal. If you want to use the phone frequently for VR, the higher the resolution, the sharper the image. Currently, there is no fine screen that would completely eliminate the visibility of the screen grid in virtual reality.

What do I need for virtual reality?

If you want to enjoy virtual reality through your mobile phone, you only need compatible VR glasses. Headsets for virtual reality are also produced for PlayStation game controllers and computers, which can bring even greater experiences.

Smartphone

For the best possible screen quality of virtual reality, display resolution is an essential parameter. In this case, we recommend selecting between phones with a screen resolution higher than Full HD, which is considered as borderline. For example, the 2560x1440px resolution has about a third of its fineness at the same diagonal. What's important is the phone's performance to keep it running smoothly, otherwise there is a risk of image jamming, which can cause nausea in virtual reality. However, high resolution screen models above Full HD 1920x1080px are currently combined with the most powerful processors.

VR smartphone headset

In order to experience virtual reality, you only need to use special glasses with your phone. You can choose from many kinds, but if the phone manufacturer offers glasses specially designed for your phone model, you are be sure of compatibility. The best example is the Samsung Gear VR headset designed for Galaxy S and Note flagships, which is among the best mobile headsets. For universal VR glasses, select according to the diagonal of the phone that they are made for.

Accessories for VR

If you want to get the most out of your virtual reality, we recommend quality headphones and a wireless controller for your phone, making it more intuitive to control and making virtual reality more enjoyable.

durable phones

Durable phones from CZK 1,000

  • They will survive trough tough conditions
  • Durable construction
  • Smartphones and keypad models
  • Always water-resistant

Durable telephones feature an enhanced IP-certified durability and resistance to dust, water, and even falls. They are available in both classic keypad phones and smartphones. If you like to do sports or outdoor activities while browsing the internet and installing any applications, a smartphone is the perfect option for you. On the other hand, compared to the keypad versions, they have the disadvantage of a significantly shorter battery life and a higher weight.

Advantages and disadvantages
  • Increased durability
  • Keypad models and smartphones
  • Different price ranges
  • Ideal for outdoor activities
  • Usually a higher weight and larger dimensions

Water-resistant phones

Water-resistant phones have the manufacturer's protection guarantee against water ingress into the phone. Modern smartphones are relatively often water-resistant with no negative impact on their design.

How is the resistance measure indicated?

An IP rating, such as IP57, is used to express the resistance. The first digits of the "IP" prefix indicate the dust-resistance or more precisely dustproofness, and the range is represented from 1 to 6. The second digit stands for water-resistance or waterproofness, and is represented by a range from 1 to 8. The most durable phones on the market are IP68 - they are fully dustproof and waterproof, you can safely immerse yourself at a certain depth for an amount of time specified by the manufacturer, but at the maximu of 1 metre deep for 30 minutes.

Shock-resistant phones

Phones that are shock-resistant are among the most durable ones to purchase. They an have increased resistance to mechanical damage or fall from a certain height and are also water-resistant. Those phones usually have several different reinforcements, a rubberised surface or other protective "jags" at their risk points. They are fit for extreme conditions, such as challenging outdoor activities or working in a risky environment.

Classic button phones

Classic (keypad) phones from CZK 450

  • Physical keypad
  • Ideal for calls and SMS
  • Very long battery life
  • Limited to basic functions

Regular keypad phones are reliable in every situation and are ideal if you expect a long battery life from your phone. They are primarily intended for making calls and writing SMS, which they manage perfectly even with a built-in physical keypad. They can also have an integrated camera, yet of a significantly lower quality than the camera of a smartphone. Due to their low cost and long service life, they are also used as back-up and travel phones.

Advantages and disadvantages
  • Customised for calls and SMS
  • Physical keypad
  • Long battery life
  • Low price
  • Weak (or no) camera
  • Small screen
  • Missing advanced smartphone features

Frequently asked questions when selecting a classic (keypad) phone

Does it make sense to buy a keypad phone nowadays?

It is true that smartphones are now commonly sold, but keypad phones still find their supporters. The keypad design suits many people who like to buy them again and again. Another advantage is their simple control and low cost. Manufacturers remember this and they still present new models, even though their offer is not as extensive as the offer of smartphones.

Can I take a photo with my keypad phone?

A built-in camera is standard even in keypad phones. However, its quality cannot be measured with neither the quality of compact cameras nor the quality of smartphones.

  • Simple control
  • Large buttons
  • An easily readable screen

Frequently asked questions when choosing a mobile phone for seniors

What is an SOS button and how does it work?

The SOS button is for emergency cases and can be with assigned one or more contacts, such as family members. When pressed, the phone usually sends an SMS to the contacts, or even calls a chosen contact, such as the emergency number 155.

How do I select a phone for seniors and what features should I look for?

Even the cheapest models, starting at CZK 500, feature large buttons, a contrastive, easy-to-read screen, and a few additional features. The phones with the SOS button are sold from CZK 700. In addition to the classic design, flip-phone devices are available at the same price. More expensive models can have a larger screen, Bluetooth support, or a more attractive design.

Some phones come with a practical charging stand, where you can simply place the phone. The user does not have to connect the charger to the phone.

The SOS Locator function featured in some Aligator phones is also useful. When the SOS button is pressed, the phone sends a link to the map with the current location of the user along with an emergency message.

Dictionary of terms - mobile phones

Dual SIM

Dual SIM phones use two GSM modules to enable the use of 2 SIM cards at the same time. On one card you can have a voice tariff and a data card on the other, or you can use the services of two operators at the same time. A large number of phones allow the use of data services in only one of the SIM slots.

Gorilla Glass

It is a type of screen protection that reduces the risk of scratches and breakage. Phone manufacturers always indicate whether they use Gorilla Glass technology, or which generation type in their specifications. Currently, there are 4 generations available, and the latest Gorilla Glass 4 has been on the market since 2014. The 5th generation promises an even better level of protection.

LTE

LTE indicates the 4th generation of the data network. The maximum theoretical data rate for the advanced LTE-A (LTE Advanced) is now up to 375Mbps for downloads and up to 50Mbps for data transmission. In contrast to the networks abroad, most Czech LTE networks are built at 800MHz, so check your phone to see if it supports this frequency.

The LTE network also operates the VoLTE (Voice Over LTE) technology, whoch allows making calls through LTE. This feature must be supported by both your operator and the phone itself. The advantages are a better sound quality and a faster call connection.

The LTE also allows you to use VoWiFi (Voice Over WiFi), which means being able to make calls through WiFi. This technology is often mistaken for VoIP (Voice over IP), which is making calls through the internet. With VoWiFi, the call is connected to the radio part of the network through your home WiFi, and it looks like you are making a call through the regular GSM network. It is especially used in locations where there is very poor signal. Once again, it must be supported by both the operator and the phone.
