[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Boomer6345:
Help! My phone is freezing / locking up and rebooting several times a day now!

I successfully did the stock AT&T Jellybean update this week when it became available via Kies.

I had no issues with the initial upgrade…it seemed to go smooth.

After a day…or a few hours….I can’t remember…I did start noticing a few issues with Touch Wiz closing or freezing and some other apps misbehaving. I can’t even remember what exactly the issues were.

I was also having some other quirky issues with the phone on stock ICS before the JB update…so I have been meaning to do a factory reset and reinstall everything.

So with the phone being even more flakey with JB I went ahead and did a factory reset with my new JB setup.

After a few hours setting up the phone with all my apps, settings, etc I noticed two issues. Swiftkey would not remain selected as my default keyboard and AT&T Voicemail viewer would not retain any of my account settings after a reboot.

After some Googling I learned that this is a know issue with JB 4.1.1 for many apps…they don’t quite install properly and something happens during shutdown that causes the settings to be lost. The only work around seemed to be:

Root Phone

Install apps

Backup with Titanium or other backup program

Uninstall apps

Restore apps – then they somehow install properly and work

I did this…first time rooting the phone….and the root and work around worked perfectly first time.

But after continuing to install apps and tweak my phone the real problems have now begun.

The phone is completely freezing at random times…in any app or in the TW launcher. It seems to just sit there frozen until I hold down the power key long enough to force a reboot or take out the battery.

There are no force closes or other error messages and I have found no other pattern to the freezes.

So now the phone is almost totally useless. It may work for a few hours…or just a few minutes before locking up. Worse…I have no way to know this has happened if the phone is in my pocket.

I did another full factory reset using the Recovery Mode and reinstalled everything again and am having the same issues.

I fear the root somehow corrupted my phone or one of my apps is totally incompatible with JB but I have to many (~70) it will be very hard to tell which one.

The other issue I am having is the battery is draining in just 4-5 hours even with light use.

Coincidentally….4G LTE was just turned on in my area this week so that would be a factor in both the battery drain and maybe even the lockups. I have a Microcell at home…wondering if 4G LTE and my Microcell are not behaving.

There are just too many variables with a new ROM (JB), fresh rooting of the phone plus recovery app installed, plus 70+ apps, plus new 4G LTE, plus my Microcell.

I don’t know what to try next to get the phone stable or to get the battery use reasonable.

Please post any and all suggestions….

One thing I’d like to clear up or eliminate is the root issue…is there any way that is the cause of my phone’s current problems?

What a mess of a week! Instead of the total awesomeness of JB, 4G LTE, and the fresh experience of using a rooted phone...all happening for me in the same week...I get a total headache and useless phone. Sure hope I can dig my way out of this.

Thanks for reading my long post!
