I will start by saying I am no expert and I will not be trying to come off as an expert. I am just a happy Droid user, and it is very much in part due to this forum. (THANK YOU EVERYONE WHO CONTRIBUTES TO THIS FORUM!!!) I would like to think of this thread as sort of a wiki, and I will need a lot of user help to make this a useful thread. SOME OF MY INFO MAY BE WRONG OR MAY NEED SOME HELP SO PLEASE CHIME IN AND CORRECT ME IF IM WRONG! Pete gives us a lot of his time and he asks nothing in return so please please please contribute if you can, and credit will be given for your knowledge. Thanks up front, and with that said...
I see a lot of the same questions being asked in the GPA13 thread. The GPA13 thread is getting pretty long, plus there are threads out there for all GPA builds so I thought it would be good to get a problems and solutions thread going to span across the GPA builds so people can reference quickly rather than navigating all the GPA release threads.
Please, if you have a problem not listed, a solution to a problem, or want to submit something, post it, or PM me so I can update this first post to keep this a "quick reference."
Edit by Pete:
If you experience any issues on the GPA builds, read the following recommendations.
By following these recommendations you can eliminate a majority of the issues being reported.
Wipe data and cache (more than once).
Do not restore your data (e.g. Titanium backup, etc).
Use the default kernel provided in the GPA build.
Do not modify the GPA build in any way (e.g. removing apps, themeing, etc.)
Be sure to have the latest baseband (C_01.43.01P).
If you continue to experience the same issue then take action by posting for support.
Loss of 3G after calls. (GPA12+ (I believe))
Cause: This is one possible cause (thank you tjk629 for pointing this out in the GPA13 thread. Thank you RW-1 continuing the pursuit to the issue.) "The 3G stuff is from Gingerbread. From what I've been hearing it's because there is no CDMA gingerbread builds out yet. So the drivers that are used to switch from voice to data don't work right." (please let me know if anyone has any other possible causes.) This issue also occurs on stock Nexus S devices running Gingerbread, more info here.
Solution: To my knowledge there is no permanent fix to this. Toggling airplane mode on and off seems to bring 3G back a little quicker for many.
No LED notifications. (All GPA builds)
Cause: My understanding of this issue is that it goes back to froyo. (please give specifics if you know them).
Solutions: Solution needed.
Phone goes into boot loop or freezes. (All GPA builds)
Cause: It seems most often, this is related to either you need to do a full wipe, or it is the kernel you are using. (Remember, a kernel that works on one device, may not work the same on another.)
Solution: Try doing a full wipe (including cache) and then reinstall. Try using a different kernel. (More solutions needed).
No sound during a call. Weird, loud noise during call (GPA13).
Cause: Cause needed.
Solutions: Reboot your device. Another possible fix (more testing and feedback needed) is to run Fix Permissions in Rom Manager. (Thank you SnoDrtRider for this tip.)
Not receiving texts. (GPA13)
Cause: Cause needed:
Solution: I do not know of a solution. It seems it may be related to using a third party messenger i.e. Handcent. (need more info please).
Getting double notifications. (All Builds)
Cause: After installing a rom from a full wipe, your phone will default to factory settings. This issue will happen if you are using a third party app for messaging because the app will have a notification, as will the android system.
Solution: Disable messaging notifications in adroid system: Open stock messaging app. Press Menu. Settings. Uncheck "Notifications."
Will not play WMA format music (All Builds)
Cause: For whatever reason WMA support was pulled from Gingerbread.
Solution: Convert music (I used iTunes), or use a different media player with WMA support.
Phone lags, Music skips, Device seems unresponsive, Device freezes. (All Builds)
Cause: There are various reasons this can happen but most seem related to the fact that GB is very CPU intensive, or it is related to the Kernel you are using.
Solution: Overclocking may be necessary for some. Pete's 600mhz kernel has been running very well (and lag free) on my device. This is not the same for all users, and you may need to run a higher kernel and clock your device to a speed that seems to work for you. (probably more solutions needed).
Haptic Feedback on camera launch goes crazy
Cause: cause needed. This issue does not hinder any functionality.
Solution: Solution needed.
Apps not Downloading from Market on 3G (GPA13)
Cause: Cause needed.
Solution: Temporary solution is to use WiFi. Permanent solution needed.
Launcher (home screen) Redraws often (all Builds)
Cause: Android treats launcher like any other app. When you are using a lot of resources (for example playing a game) the system will kill apps that are running to free up resources (launcher included). Because GB is so CPU intensive, you may experience this problem.
Solution: Download terminal emulator from market. Run TU and type SU then press enter. Approve superuser permissions. Then type echo ro.HOME_APP_ADJ=1 >> /data/local.prop and press enter. Then reboot. This should lock launcher into the phones memory and avoid redraws. (Thanks to juhde for posting and bringing the local.prop script to us. This has been a huge help to me. And thnk you Bobbar the testing you did on local.prop in GB).
So as of now, this is a wiki in need of much contribution. Please help out with any info related to any of the GPA builds.
