Add SP Touch problem when charging to Bugs on Wiki
I request someone to update the list of Known Bugs of the phone with the "Xperia SP Touch problem when charging".
I have this bug on a phone manufactured in Sept 2013 (and latest firmware), and I find lots of people on the net who have the same problem.
i.e. the touch intermittently stops working when charging, and sometimes even sends phantom touches.
Note: I am new to XDA and android, so I didn't edit the wiki myself.
