Users did not benefit much from the lack of necessary features. However, the demands of developers and phone manufacturers have become important to Google.
Google has stopped providing information on how many new OS is running on the device. They are avoiding the issue as the upgrade process is quite flawed. Not all Android devices are updated at all. Due to this, the interest of Android fans naturally decreases. Updates are available for individual models of each brand; It also takes a few months. Because manufacturers have to make chips that are compatible with the OS. Then the phone companies modify the OST.
Google has also stopped providing the features that will be useful to the users. For example, the bubbles feature of Android 11 has been created keeping in mind the developers.
The feature is made sure that they stop using the screen overlay. He did not consider whether it would be useful to users. What's in the new OS update is often already available on Samsung and LG devices.
Various features of Google, Chrome, Photos and Gmail apps are also available by updating the app. Full system upgrades are not required.
