My device problem was earpiece sometimes not working, didn't work during a call (I couldn't hear what people said, but people could hear my voice). I installed SoundAbout Pro, inside the app I tick the phone call to earpiece. Almost 100% fix, but one a day I'd experienced the problem exist again. At that time when the problem appeared again, I tap (not squeeze) the top the device, the earpiece wored again. Squeeze near earpiece area may work too, but I don't like to do it. Just tap on the top I fix. If I am not mistaken, the problem reappeared again two or three times only, after two or three times, no problem again.
