I understand some get the update and have no issues, but according to the forums your the lucky ones. I also did a cache wipe, after I was still having issues I deleted and reinstalled the app having issues, what happened after that, those apps worked, then another app starting acting up that was working fine, so that's when I decided a FDR was needed.
Just allow us to choose to update the OS, and give option to go back if there are issues. It's that simple
In developer options, I found this option. Will this prevent the new OS from being installed on your phone.
