You could either repair your tablet with SUS and if that doesn't work, stop by your local Sony

I am having this exact same problem with both Xperia Z tablet AND my Xperia M phone. Since new, both Xperias are virtually unusable while charging/plugged in. The screen goes crazy, swipe goes haywire, touch won't work then will suddenly click on something 10 times in a row, or random things will open that weren't touched. It's really frustrating and I assumed it was just how Xperias behaved, but it's hard to find anyone else with this issue. 

I'm about to buy the Xperia M4 aqua compact, but don't want to if this is an inherent issue with all Xperia phones. Can anyone shed some light on this for me? Thanks!
