I have this without charger. Sometimes it is ok for a couple of minutes (especially after a restart) but soon it starts and mostly on the same screen spot 🙁 Just took off the plastic protector, no help !! Big bummer as I really like this ablet.
Update : I managed to get back on the plastic screen protector (boy, what a job, but with the help of some soap, I’ve managed it without bubbels) and is beter applied than originally. Now the isue still appears and automatically activate some touch points, but less frequently. Will test it a bit more the next couple of days ?
