Google ota upgrade system (Google is committed to improving OTA updates for some Android phones)

If you have an Android phone, you may know that it needs to be unlocked after you update it and restart it. In this way, all applications can start running normally after the update. However, suppose you plan to update at night; this means that the phone will be locked until you get up the next morning. As a result, these applications are not ready in the morning, so you may miss some important announcements. Nothing sets the tone for a bad day more than missing an important announcement in the morning.

XDA reported that Google is developing a new feature called "restore after restart". After installing the OTA update, the latter does not require Android users to log in. Therefore, this feature will store your login information and use it to automatically unlock your phone after update. In this way, the application can start running immediately without waiting for you to unlock the device.

Continue to display on Android Gerrit when rebooting.

In order for this feature to work on Android phones, the phone must have a programming layer called ireboot hosting. This means that not every Android phone can use restart recovery. The latter has already appeared on Android Gerrit, and there are reports that Google is testing it on Pixel 4. Most importantly, this feature could lead to seamless updates to flagship Android phones.
