Hi,

My phone sometimes just restarts suddenly like it crashed and gets stuck at the Android screen. This has happened twice - first when I was listening to some songs, and the second time while the screen was unlocked.

The first time, I noticed that the SD card suddenly became unmounted and after a few seconds the phone rebooted from the Android screen, but gets stuck there.

The second time, I took the phone out of my pocket and found it stuck at the Android screen.

In both cases, the power button didn't work and I had to remove the battery and replace it to fix the problem.

In both cases, I wasn't running too many apps - the first case, just the music player and some background apps, the second time, just the background apps.

I am a root user with stock 2.2.2 ROM, and I use Link2SD. I have had 2 SD card unmount problems in the past, but it hasn't happened for almost 2 months. Dont know if its related.

Any help would be appreciated, thanks.
