Question is pretty self-explanatory. I did not see anything relevant in web search results. Could you point me at some tutorials?
Details: My phone locks up at random, during various workflows. If I leave the phone in locked-up state for 5-10 minutes, it reboots all by itself, probably with a watchdog. I have contacted T-Mobile, and they promised a replacement. I am a software dev, so I'd like a stab at debugging this issue before reaching for a hardware solution.
