Black Screen of Death [BSOD]
Solution: on Razr models [where battery not accessible/glued in], hold volume down & power at the same time for 10 secs. Does a force reboot [same thing as a battery pull on Bionic]
Cause: No clear cut answer.. would have to hook it to a computer and have the error occur while dmesg/logcatting.. since it occurs randomly, there are only theories. Most logical one to me.. or the one I'd explore first if I owned this device is.. the 3G to LTE handoff.. so if you are in a 4G area but lower reception and it toggles back and forth [your actually switching from a (native) cdma signal to a gsm (sim controlled) signal]. This has caused issues in other manufacturers' phones with Verizon, but manifests itself in different ways.
Anyway other than theories, there doesn't seem to be anything concrete out there yet. My dad got a Razr M (and had the BSOD occur); so, I been searching. ;)
Motorola RAZR Maxx Screen Keeps Going Black
Same problem here with my RAZR Maxx, it has gotten progressively worse over past few months to a point that it does not work at all once screen is turned off, as in hitting power button after call to turn off screen, but it won't come back on unless I reboot. I don't use the phone much away from computer, so I leave it plugged into USB port and set screen to stay on as long as it is plugged into computer, so I can at least deal with it, but phone is useless when not plugged in. Screen can only be set to stay on for 10 min., and as soon as it goes off, won't come back on. Phone can still receive calls, but I cannot answer them. Total pain in the ass since contract is not up for another six months. I have totally stock phone, very few apps added which never gave a problem when downloaded. Any idea which app may be causing this issue since it is consistent, not a problem with phone as I see it.
