Ok, I'm at my wits end here. I got annoyed with the last update which caused battery and signal issues, so I decided to root and try CM10.1. Now I have a several problems: 1. The Camera stopped working. Every time I open the app it says "Camera Error", "Can't connect to the camera" 2. The phone no longer recognizes the external SD card. When I go into settings->storage-> it says "Insert an SD card for mounting" with no option to actually mount. I've tried reformatting the 32GB card as FAT32 with Windows 7 and with EaseUS Partition Master. I also tried a spare 512MB SD card I had laying around. No luck. Also, cannot mount in CWM. 3. Signal appears to be worse than before. Before the OEM update I has fair 4G in my office, after the update I had fair 3G in my office, now I get a blip of 3G here and there. I've tried multiple ROMs, including CM10.10 RC5, CM10.1-20130411 M snapshot, CleanROM 6 R2, and AOKP Milestone 1. None of these ROMs fix any of the three problems listed above. Any help would be greatly appreciated.
