Since there are so many different kinds of problems being reported after the last two Android updates I am wondering if the problem lays with a conflict between the two updates. 4.2.2 supplemental security update was only released a couple of weeks before 4.3. There were a few problems with the security update, but the majority are now coming after 4.3. The two updates just might be at war with each other.
I have yet to update either one of them, but was wondering if anyone here has just installed only the 4.3 update and if they did if they encountered any problems?
If I do decide to install the updates my plan is to back up every thing on the phone and do a factory reset before the first update is downloaded, install the first then do a factory reset again, download the second and install it then do a third fatory reset. I will not reload any apps back to the phone until I find out if the phone is working without all the problems listed from others here. Any apps I do reinstall will be downloaded from the play store instead of using a backed up copy. This is a lot of work and when I have a day to do this it will well be woth the extra time involved..
