Android is the most popular mobile phone operating system. Each manufacturer can customise it for their devices, and any developer can create an extension. That's why you'll find a variety of diverse apps on Google Play. Compared to iOS or Windows, however, it puts higher requirements on the hardware and the battery. What are the main differences between the individual Android versions and what are the parameters to consider when choosing a smartphone with this operating system?

Android version news

Jelly Bean (4.1 - 4.3.1, complete support)

The Google Now assistant allows you to create voice commands, and the drop-down notification bar allows for an immediate response directly from the notification.

KitKat (4.4 - 4.4.4, complete support)

The "Ok Google" command makes it easy for you to search, send SMS, retrieve route information, or play tracks with the help of your voice. The smart dialling function prepares the contacts you call most often to ensure a caller identification and a spam protection.

Lollipop (5.0 - 5.1.1)

It uses a shadow and movement design. With the Android Multiscreen function, you can smoothly switch between your phone, tablet, watch, and Android TV and immediately continue listening to music, using an app, viewing photos, or browsing. The notifications are moved through a locked screen, where they are displayed in order on cards with the option to answer directly from the locked screen. You can also switch user accounts on a mobile phone.

Marshmallow (6.0 - 6.0.1)

The "Now On Tap" function launches the search as soon as you hold your finger on the home button. You can decide what data and features you will share with the applications through the permissions. The new Doze or Standby applications are now available to optimise your battery usage.

Nugget (7.0 - 7.1)

When texting, you can use the updated and new emoji icons (1,500 + 72 new icons) and two languages at the same time. The system can run two apps side by side and combine, for example, a video with a text editor. The Daydream-ready phones have a special Virtual Reality (VR) mode. Other interesting features include enhanced notifications or an advanced security and encryption.

Oreo (8.0 - 8.1)

Android Oreo looks just like a rejuvenated 7 version, however, this operating system is much more sophisticated when it comes to its functionality. The PIP (picture-in-picture) feature lets you watch videos while chatting. An interesting novelty is the notification reminder function or their background colouration. Many other changes are not as visible, but you will definitely welcome them - a half-length device start, an automatic web form filling, and especially the Project Treble, which allows for updates without a dependency on the device manufacturer.

Important parameters to consider when choosing an Android phone

Display size

  • 4-5" - an enjoyable compact size for most users. These devices are easy to handle, while they are also great for watching videos.
  • 5-5.5" - great for watching videos and browsing the Internet, but they are not as compact and you can feel them in your pocket.
  • 5.5-5.9" - these phones are called "phablets". This is a compromise between a phone and a tablet. The size of the display is large enough to be able to conveniently watch videos, browse the Internet and work. However, it can only fit into a large pocket or into a backpack.
  • 6" and more - these phones are specifically designed for productivity. They are great for browsing the Internet, you can enjoy movies and games, but carrying one in your pocket can be an issue. However, you will definitely have a blast multitasking.

Operating memory (RAM)

  • Up to 1.5GB - an unproblematic functionality while playing basic games and using only a few applications at the same time.
  • 2-3GB - can handle challenging games and a large number of running applications simultaneously.
  • 4 GB or more - the phone does not freeze even during the most demanding operations (editing videos and photos). Playing games with the best settings is a sure thing.

Storage size

Most Android phones have an internal memory between 16 and 64GB, but the operating system is part of it. Pure Android reduces the capacity by 4-10GB, graphics and more. A great advantage of these phones is, with a few exceptions, the ability to extend their storage with a memory card, up to 256GB. Dozens of movies, games and apps will be able to fit into this storage.

  • 16GB - can hold several apps and hundreds of music files. This size is only suitable for undemanding users who do not take many pictures or record videos.
  • 64GB - for dozens of apps, games, music albums and several movies. It will be sufficient for most users.
  • 256GB - suitable for the most demanding users who record high-definition videos, store movies, or music and many applications.

Camera

  • Resolution - phones with a 12Mpx sensor resolution can take great images. The good front camera has at least 5Mpx. However, the resolution is not everything. The image quality also depends on the optical quality of the lens.
  • Maximum luminance - determines how much light passes through the optics and falls on the sensor. A F/2.0 and lower luminance are outstanding (the photos will look good even in the dark or during the night).
  • Optical image stabilisation - the phone tries to stabilise the image itself to ensure unblurred images and a more stable video recording. Unlike the software stabilisation, it is implemented by the optics or a sensor shift.
  • Software image stabilisation - works on the principle of increasing the ISO sensitivity. You capture sharper images but it's not as effective as the optical stabilisation.
  • Dual camera - it can accelerate the focus, increase the luminosity, change the focus area after capturing an image, and adjust the field depth. However, the dual camera capabilities and features are different and depend on each specific phone.

Design

  • Metal (aluminium) - a very elegant solution. Typically, these phones belong among the mid-range, upper mid-range and premium range phones (they are usually more expensive).
  • Plastic - the domain of inexpensive phones.
  • Combined - a metal frame with a plastic rear and sometimes a plastic front panel. These are lower and mid-range mobile phones.

Useful features

  • Fingerprint reader - to unlock your phone or access selected applications.
  • USB OTG - allows you to connect a flash drive or an external data drive through a reduction.
  • Notification diode - it flashes when you have unread messages, missed calls, and other unread notifications.
  • Dual SIM - allows you to insert two SIM cards into your phone.
  • A water and dust resistance according to the ingress protection (IP).
  • NFC - a wireless technology suitable, for instance, for mobile phone payments.
