Although Android is open source, the real changes are being made by Google, which has put new conditions in place to make the system run more smoothly.
Google has finally laid out everything it needs to run Android 12 on a smartphone.
The Android Compatibility definition file has always been a part of the Android ecosystem. This is done to ensure consistent API and platform behavior across Android devices.
If, for some reason, the device fails to meet the requirements listed in the CDD, it may fail Google's compatibility test suite, causing Google's Suite of applications to be lost. In Android 12, CDD brings some new changes. However, most of these are small and will only affect Oems.
For some of the key requirements of Android 12, Google says the device must have at least 6GB of memory.
Screens must be at least 400dpi pixel density and 1080p resolution. At least 120MB/s continuous write speed, 250MB/s continuous read speed, 10MB/s random write speed, and 40MB/s random read speed are required.
Phones must have at least a 12 megapixel rear camera capable of 4K 30 FPS shooting and a 4 megapixel front camera capable of 1080p FPS shooting.
Performance ratings can be helpful to developers, so they can improve not only the overall experience of devices that meet performance ratings requirements, but also the experience of devices at the lower or middle end of the spec sheet.
For the above conditions, Samsung, LG and other manufacturers are also the first to respond and support, so as to create a positive and good ecological environment.
