Hello everyone, recently I got my I7500, couldnt use it on all networks so I unlocked it. Was no problem for 1 day and then IT started: buttons <menu> and <call> doesnt work all the time. Call button works only when I have to answer or right after I press side button for volume control. Call button doesnt work when I press it, when I have to call someone, when I have to answer and phone is in silent mode. Menu button works only after I press side buttons for volume control. Any idea what it can be. I did hard reset, but problems are still here, sometimes it works for couple seconds but that is not what I want Thank you in advance for your response.
