Today I installed the 3.4 upgrade. The download was very slow but it eventually completed, and upon rebooting, I found that the update reset my dock and launcher app layout. All apps are now sorted in alphabetical order, and the dock was reset to what I assume is the default.
In other settings, I also noticed that vibration was turned back on for navigation and keyboard touches. This one was easy to spot. I worry that other setting changes won’t be as obvious to spot.
I assume there is no way to recover? Was this expected from the upgrade?
3.4 moved some handsets to Android 15. I could imagine a version change also reverting some settings. Maybe if you told us some details, people could help?
