[Galaxy S II Q&A, Help & Troubleshooting] jevermeister:
AVG did not find anything at my galaxy.

My phone (2.3.4) has a habit of rebooting nearly every 24 hours +/-1 hour.

It is also booting again every 2 Minutes and I got a lot of FCs until I manually shut it down and restart it, then 24 hours later the same game.

Yesterday I had luck and collected a lock with "stability test" but I fear the mail was incomplete:

This is the mail I sent myswelf:

It looks like StabilityTest crashed unexpectedly or your device rebooted.
The following information were gathered right before the event occured:

cores: 2
bogomips: 1592.52
load: 13.59

temperature: 41.0°C

# passed test runs (core 1): 3
# passed test runs (core 2): 3
# passed test runs (ram): 40
runtime: 00:04:04
