Anyone knows anything about this? It's happening on my L730, although on my L930 it works fine. Let me know.

It seems the only solution for this is a hard reset to return your phone to factory settings.

To do a hard reset:
1. Press and hold the volume down and power buttons at the same time until you feel a vibration (about 10–15 seconds).
2. When you feel the vibration, immediately press and hold the volume down button until you see a large exclamation mark.
3. Once the exclamation mark appears, press the following four buttons in this order: volume up button, volume down button, power button, volume down button. Your phone should now reset and restart itself. (It might take a while for the reset to finish.)

Don't forget to make a backup before you do a hard reset.
