FP5: Android 15 killing background apps more aggressively

If your mind is set and the wiping of user data and the resulting aftermath are clear and accepted as a consequence, at least the factory reset itself will be done easily and quickly.

But please keep in mind …

If the OS upgrade was done in-place via the updater, a factory reset will not rule out the upgrading process as a possible source of issues.

There is a point in trying a factory reset or, more cleanly, an install from scratch if there are users out there with the same phone and OS version, but without the issue(s).
