After a few month happy with my e52 I have encountered a strange issue. A minute or so after I turn the phone on the "2" returns the info of a "4" and the "end call" returns a "1". "#" returns a "6". All other keys are as usual. The phone hasn't been dropped or wet. It was in my pocket when the problem started. The phone has been updated to latest firmware, but it didn't solve the problem.
Hope someone can help me
