What about a bad speaker?Recently, I lost audio and can't hear anything coming out of my tablet speakers, any ideas to get it working?
"Touchscreen clicking on apps by itself"に関する回答Try following the recalibration instructions on the tablet. If the calibration has been altered, it could cause the problem. If your screen has anything on it, it could cause apps to open. Make sure there is no dirt or traces of water on the screen.
