I have realised that if i keep my device off for a long time and then switch it on. For a few minutes after turing ON, the touch Screen works when i also make physical touch onto any metallic surface like sd slot casing etc behind( i have opened up the back cover and it seems i need to also have some contact with the inside part like usb port/ sd slot metallic casing for the touch screen to function). However after few minutes the touch screen stops responding, the light on the power button glows each time the screen is touched but.. . the physical keys are working though allowing to shift forward or backward if a document is open. But selection on the screen is not possible, rendering the device unusable after few minutes.
is there is possible software solution ?
Any help possible? , it would mean a lot!!
