There are currently no spectacular user changes, but behind the scenes, Android is still developing nicely, and manufacturers are working more and more enthusiastically on generational updates of their own interface. Of course, the official start of Android 14 is still a long way off, so it’s still for the manufacturer versions, but Google published the earliest test version as scheduled, targeting developers in the first round (developer preview 1). This will be followed by the second developer preview in March, then the actual open beta will start from April until the platform stability at the end of the summer, and if everything is fine with the latest version, the official release will come.

Android 14 is UpsideDownCake, or Reverse Cake, has been given the name Cake, and the first developer pack with the February security patch package can be installed on Pixel 7 Pro, Pixel 7, Pixel 6a, Pixel 6 Pro, Pixel 6, Pixel 5a 5G, Pixel 5 and Pixel 4a (5G) . Since Android 12L, Google has paid more attention to the large screen and multiple aspect ratios, and now developers get more hints for relevant optimization, including adaptive layout. Android 14 promises more economical background consumption when applications have only minor tasks, and in certain situations, developers will be obliged to include battery-saving solutions in their applications, so that an unwanted process does not get stuck and drain the battery unintentionally.

Google further refines the gesture control with a predictive finger movement back, so that, for example, when the screen is turned, it is clear which movement (vertical, horizontal) involves going back or going to the main page. Android will natively support the satellite data connection, just like the iPhone 14 and iOS, of course you will need the appropriate hardware for this, and Bluetooth can measure distance based on signal strength and be more effective in finding your lost gadget. These are just some of the many small changes, which are primarily intended for developers, but other innovations will also arrive over time. The bottom line: those who are really brave can get involved right now, but those who are just a little adventurous and somewhat cautious are better off joining the Android 14 party at the first official beta.
