Hello - as per the title really and exactly the same fault as the video someone posted on here a while back: https://youtu.be/t3iZsqKSyRQ Does anyone know if it is possible to recalibrate the touchscreen in software or has anyone else had this problem and found a fix? It's still in warranty but since this fault seems to be fairly common I'm wondering whether to just reject it under the sale of goods act. It's 18 months old but has had very little use.
