Does anybody know how to solve this problem:
I'm using my K750i with a BT headset (B-Speech plus) and sometimes at
home with a BT dongle (LevelOne MDU-0025USB). Everything works fine, but
after a while my phone hangs. It doesn't accept any keystrokes any more.
All I can do then is releasing the battery and turning it on again. I
don't really know, but I think that this problem has begun after i
upgraded the phone's software to the latest version. Well, can anybody
help me? Is it possible do make a software downgrade?
Thanks a lot,
Martin
