e If you upgraded to CM7.1 on your Galaxy SII then you may well be experiencing some major issues right now. The CM Team that worked on the release have now removed the stable tag from the ROM upgrade and re-classified it as a Release Candidate
- Constant loss of Cell data connection
- Inconsistent and irregular Bluetooth support.
- Wifi issues with drops and pauses. Mostly fixed with proper WPA supplicant.
- Apps dependent on regular data connection often crash, most likely related to communication between baseband and Android.
- Regular app Force Closes, even after permissions are repaired.
- No WPS support (pin, PBC, etc)
- Camera app crashes
The above list are pretty much what caused the team to re-classify the code drop. The have however that when ready they will release a 7.1+ ROM to resolve the noted issues though there is no date or estimated date for that as yet.
