I have a sim-unlocked T-Mobile HD7 that I've upgraded to latest 8107 some time ago via cab-sender.
Officially T-Mobile doesn't support 7720+ afaik.
The only problem that I have is that the screen remains black after I take the phone away from my face/ear. Also the screen automatically goes black when I hit dial although it's not near my face/ear.
Is anyone know how can I fix this?
I had this stupid bug on a intermediate build before Mango on an unlocked HD7, but when the official ROM for HD7 come out, it was solved. Now I'm stuck again with it...
