Phone keeps freezing and crashing at unlock

[Amazonfemme]

For the last couple of weeks, my S3 has been freezing sometimes when I try to unlock it (I use the Face Unlock feature). It's not the same reaction every time; sometimes I get past the unlock screen, but the widgets take forever to load ... then the screen goes black (but the status bar is visible) and then returns to the lock screen. Other times, it freezes on my Face Unlock image; other times, it doesn't recognize my face and kicks me to the PIN login screen, then freezes there. Sometimes it freezes on multiple images -- ghosted, so that the PIN screen is frozen on top of the Face Lock image. I can't turn it off when it freezes or goes to black; sometimes it unfreezes and goes back to the lock screen, while other times it goes to the Verizon screen. Eventually it returns to the lock screen.

Pulling the battery doesn't fix it; it's just as likely to freeze and crash after a battery pull as before one. I've tried booting into CWM and clearing cache and dalvik cache, but that doesn't help, either.

This morning, it woke up fine, but froze when I got in the car and tried to turn on bluetooth. From that point on, over the next 30 minutes, it froze and/or crashed 20 times. The 21st time, it suddenly decided to play nice and has been working fine ever since.

I'm rooted (using the updated VZW stock image), on Android 4.0.4, no ROMs yet, running Nova Launcher Prime. Used TiBu to freeze a lot of bloatware; I run Juice Defender, Lux, Screebl, and AdAway. Is there a way to find out what's causing the freezing and crashing?

Your running this one

[ROM] PROPER Remake of Rooted Stock Image [Verizon]

Not the first Sprint based one right?

[Amazonfemme]

Right.

I suppose you could put it back to stock. Factory reset and just root it and see if that clears it up.

or load a ROM
or stop using face unlock. Could be trying to tell you something

Have been tearing my hair out over this issue for ages (to the point of returning my phone) but think I have found the solution (thanks xda-developers) If anyone else having this issue try this
go to settings\wi-fi\Advanced and turn off network notification.

Appears to be a bug that may have been introduced in the latest update (wasnt causing me probs before). Hopefully samsung will sort it in next update. Since I have done this the screen freezes have (fingers crossed) been irradicated.

Thanks CR6. With regards to this I did encounter another screen freeze after deploying the above fix. After another trawl around the forum I have applied this workaround.

On the dialer type: *#0011#
Then press menu -> wifi, there is a button ON ( power saving or something ), change it to OFF.

This appears definately to be related to wifi. Will let you all know if this workaround fixes the issue. By turning this off I expect my battery to drain quicker but I can live with it as I turn wifi off most of the time. As I say will keep you informed
