Screen doing its own thing like touch disease
I replaced a digitizer on this some time ago and the customer has come back to me saying the screen does what it wants and types like its got touch disease.
I've done a bit of research into this and I cannot see a confirmed case of touch disease on an iPad. I've cleaned the digitizer and its still acting weird, It also changed the volume on its own too. I have managed to capture it on a video (link provided)
Any ideas what it could be? I'm along the lines of this is a board issue. I suspect there is a problem with a data line or cpu where the Ipad is receiving a bunch of nonsense signals.
