Songs stops/skips when carrying my iphone in my pocket

[guitarbjorn]

Mostly when I carry my iphone in my pocket and listening, the songs skips and or stops. I've found out that the *slightest* touch on the left side of the iphone makes this happens. And that's when my the screen is locked (dark). I can see that it seems like a common issue, but the solutions suggessted, dosen't work (re-installation, update app, changing ear-phones).

I hope someone can help me fix this bug
