Stock 2.3.3 here... factory reset a couple of times, and #1 still happens, and I haven't figured out what's causing #2 yet:
1) When I go to settings>applications>manage apps - 95% of the time, when I click on a specific app, I have to back out and re-select it, sometimes more than once, b/c it's constantly recalculating the data/space it's using, and the buttons like "clear data" and "clear cache" are constantly flickering - i.e. you can't uninstall or do anything. Eventually, after one (or more) backout/reselect it'll work normal.
2) This is the weird one, and the important one, b/c it causes me to not be able to open the phone app... All of a sudden my google account seems to be removed from my phone, and I start getting the "process.android.acore" error when I try and open the phone, and occasionally get "The application Google Services Framework (process com.google.process.gapps) has stopped unexpectedly, please try again". This has happened to me twice, and the only thing that fixed it was a factory reset. I'm not resetting yet this time since it's the weekend and I don't need my phone as much, but I can't pinpoint what's causing it.
My google account disappearing might be a result of the errors, can't tell... and I also can't tell if the two issues are related. #1 is ongoing, #2 only happens occasionally.
Anybody experienced any of this or have any thoughts?
