I have been using the I9100 for the 3rd year now, and about a week ago, i started to get the following bug:
When I am in a call, sometimes, without me doing anything, i stop hearing the other side.
When I try to hang up and end the call, i press the red button - AND NOTHING HAPPENS.
For 5-10 minutes while the phone stuck in a "call state", the call disconnects and the phone seems to return to its senses.
Other solution is to restart the phone - all that is really frustrating because it still takes about 5 minutes to return to the call - which sometimes can be important.
Anyone experienced such problem - and maybe found a solution?
