Help Galaxy S3 Launcher Not Responding

[mikem3223]

So my Galaxy S3’s launcher, both the TouchWiz (native) and GO Launcher EX have started to crash, seemingly at random. I get the ‘GO Launcher EX is not responding.’ ‘Close or Wait?’ When that happened a few times, I decided to try running the native TouchWiz, but it happened with that too, only with TouchWiz is not responding as the message instead.

Closing it just freezes the phone with a blank, black display and the Menu and Back buttons lit up.

The only thing that gets it out of the frozen state is a hard restart (removing and replacing battery).

It has done this while I’m texting, while I’m driving and listening to a podcast, while it’s in my pocket idle, and while charging. I’ve used 2 different (OEM) batteries and not seen a difference.
I uninstalled all recently installed apps and I’m only running one app that isn’t “trusted.” The crashing happened long after I started using it.

Has anyone seen this issue and / or know what the cause and solution are? Factory data reset is a last resort.

hmmm....I would suggest either disable that "untrusted" app just to see if perhaps it isn't starting to misbehave?
Otherwise, I assume you are not rooted, but you can still boot into the stock recovery and clear cache and dalvik from there and reboot to see if that changes your issue.

Correct, I'm not rooted. How do I boot into the stock recovery?

I cleared cache. Is there a tutorial for how to dalvik after clearing cache? I'm clearly not as advanced a user.

Also, I forgot to mention that I tried to install a few untrusted apps that showed up as possible threats, then deleted the files. Is there a good malware scanner?

For recovery, turn phone off then power it up holding power, home and volume up :thumbup:
I cant remember how the menu is layed out in stock recovery tbh

I'm confused by all this nomenclature: what is a launcher, dalvik, stock recovery???

If anyone is curious, or experiencing a similar problem, I uninstalled GO Power Manager and it seems to have solved the problem. It was likely clashing with another application.
