Is there some hack which I can use to disable automatic check and installation of system updates on an Android One device? I have my device rooted and the automatic installation attempt breaks my Magisk > Restore images functionality as the partitions are locked for editing when the system_updater puts it to use. And then does not leave them free until reboot.
The developer options do have a setting regarding "Automatic System Updates". I did diable it, but all it stops is the Automatic application of the update when I reboot. That is, it does check for the updates, it does the verification and installation and then asks me to reboot. The only difference the toggle makes is that the device does not automatically change to the new slot when I reboot normally.
I am looking for something which can help me in postponing the check for updates until I manually tap on it. If that is too much, at least the update should not download and install without my permission. Google seems to be copying the annoying Windows 10 kind of update process for Android One now.
