    Since the upgrade to ICS 4.0.4, my Nexus S 4g has begun locking up just after the screen goes to sleep. Even though this could be a hardware issue, this never occurred with 2.3.7. My upgrade was a stock over the air upgrade to 4.0.4. Sometimes I get the recovery screen, (Android mascot with red exclamation triangle over belly) and sometimes I only get a white Google necessitating battery removal and multiple boot attempts.

    If I leave it plugged in with Stay Awake selected from the developer options menu, the phone can go mulitple days without locking up. If I remember to interact with the phone more frequently than the sleep setting, it never crashes. But if I leave it on battery and let it go to sleep, it locks up soon after the go to sleep interval.

    Is there anything that happens just before sleep that could be causing this?

    So far, I've tried a factory reset and erasing all usb storage. It seemed to be more stable for a little while, i.e. I could let the phone go to sleep and wake it up. But over the course of 2-3 hours as all my apps returned, the lock up started again.

    Any suggestions for debugging this?

    If you claimed it stopped for a while after the factory reset and then started once again after your applications returned from your Google auto backup/restore option then I would say its a rogue app causing issues.

    Something you have on your device just might not be playing nice with ICS.

    Certainly the most logical explanation.

    I agree this seems logical. However, I am at a loss as to how to debug this. I have the log collector application, but it seems logs are gone by the time I reboot.

    I do have the android sdk installed. Is there anything to be learned by connecting after the problem occurs? I have not tried this and I do expect the phone to be unresponsive, though.

    It seems others are reporting something similar as well:

    The issue is within your settings. Enter your settings menu and click the security section. Within the security section you can change if you want the screen to lock up right after the screen turns off.

    Right, but when I say locks up I mean that the phone becomes unresponsive and I have to pull the battery to get it to restart. Sometimes I get the broken android man and sometimes I don't

    I am getting the same issue. I thought it was an apps so I reinstalled it and I am still getting this issue without any apps. Also, after a while all my apps will say "Unfortunately <app> as stopped" and will shut down. I have to reboot to fix either one of these.

    I reinstalled it by flashing 2.3.7 again and then using the OTA update to put it back to 4.0.4.

    My dad's Nexus S has the exact same issue after upgrading to ICS. My mom has the same phone, upgraded it to ICS over the air and doesn't have the issue.

    Repeating the problem: the screen goes to sleep after timeout like normal, but then you can't wake the phone back up. It's unresponsive...and you have to pull the battery.

    I thought it would be a rouge app, but can't seem to figure it out. I HAVE factory reset it, then installed just a couple apps, and still have the issue. Very weird. Any help or ideas would be appreciated.

    Hi,

    As the original poster, I thought I would update my experience. In the end, I could never find the issue and I just sent it to Samsung in Richardson, TX for repair under warranty. It was free, but I was without my phone for 3 weeks.

    The only explaination I got out was
    • Identified Faulty Component
    • Replaced Faulty Component
    • Failed final test
    • On-hold for back-ordered component
    • Replaced Faulty Component.


    It has worked solidly since.

    The only lockscreen issue I'm having is it is a lil laggy but only when hot or running a lot of apps

    This this fix your issue? I'm thinking of attempting the same thing - but I have to root the phone first. Thanks for any help.

    Thinking about doing this as well. I don't have insurance on my phone and I know i'm going to have to pay out of pocket for Sprint to give me a refurb. My phone has progressively gotten worse with the 'freezing' randomly and on startup.
