[Thunderbolt Q&A, Help & Troubleshooting] Kitten Mittens:
I've been on CM7 since RC 0.3 or so (if I remember correctly) and I absolutely love it, after getting cozy with CM7 on my Incredible, I definitely wouldn't have upgraded to the Thunderbolt if it didn't already have CM7 support. That said, I have been experiencing a few bugs as recently as on 1.2, although I don't know exactly when they first appeared, and I have tried a wipe / clean install of 1.2 with no luck. These are mostly minor issues that certainly don't take away from the great overall experience of CM7, and as far as I know might not even be specific to CM7 as it's the only ROM I use, I just hope someone here might know what exactly is going on. I have experienced all of these issues even after a wipe and clean install of 1.2. I installed 1.3 earlier today but I haven't had the chance yet to check if all of these "bugs" are still present, so I apologize if this is premature, but I will update this if these issues seem to have been resolved. Also I'm using the MR2.5 radio if it's important.

I go out of town about every other weekend (roughly a 3 hour drive each way), and I keep my Thunderbolt mounted and plugged into a car charger for the trip. I always use Google Maps / Navigation, and listen to music in the background (Google Music or Pandora) from the 3.5mm headset jack going to the car stereo. Anyways, as of recently I seem to be experiencing a few problems nearly every time I make this trip...

Bug #1 - I usually leave the phone on the Navigation screen for extended lengths of time will driving with music playing in the background, every once in a while I will fiddle with the phone to change the music, check texts etc. but then I go right back to Navigation and I don't lock the screen. On the Thunderbolt, for some reason at some point during the trip (It seems to start happening after about an hour or so of driving), even if I set "screen timeout" to 5 minutes, the display will all of a sudden get really dim on the navigation screen after a minute or two without touching the phone. The display doesn't turn off after any length of time after that, just stays dim until I touch it. I tap the screen and then it lights back up to the correct brightness but after a minute or so it goes dim again, this can get really frustrating especially when driving in bright daylight when I have to set the brightness at or near 100% just to be able to read it, and when it goes dim the brightness looks like it's less than 25%. I'm left routinely tapping the screen for over an hour and a half, or I force myself to ignore it and check it much less often.

I was under the impression that when in the Navigation screen the display should stay at the set brightness level, and shouldn't go dim or shut off after any set amount of time like it would normally in any other screen (this is at least what my Incredible on CM7 does), is this correct? If not then disregard this "bug" report.

Bug #2 - At certain points during the trip I hit bad coverage, as to be expected. From what I assume to be caused by the radio, either in the process of switching between different cell towers / searching for service / generally network issues, the phone will just completely shut off out of nowhere (from fully up and running to completely powered down in an instant, like if I were to pull the battery). I hold the power button down and it boots back up and seems like there are no problems. It doesn't happen every time but it can happen up to two or three times throughout the 3 hour drive. It is worth mentioning that this has only happened to me during this trip, never while I'm driving within a city etc. Is this related to the Gingerbread bricking? I have not read enough to know exactly what the symptoms are.

Bug #3. After taking a picture with the default camera app with flash set to "on" the display brightness jumps to 100% brightness or at least very bright (I have automatic brightness turned off, set to ~30% or so usually), but then when I go to "settings -> display -> brightness" to check the brightness level, the slider incorrectly shows my normal brightness setting and I have to move it to get it to correct itself. I have checked and this is still happening to me on 1.3, and as I said earlier I don't know if this is strictly a CM7 thing as it's the only ROM I use.

These are just a few off the top of my head, I'm sure I've run into a few other problems, I just can't remember anything else specifically.

TL;DR version:

1. Navigation screen goes dim after a few minutes.

2. Random complete shutdowns, presumably related to the radio?

3. Taking a picture with flash sets brightness to 100%.
