Why isn't the touch screen responding?

My touch screen will not recognize that I am touching it. I can wake the device up, but it stays still on either the home or lock screen and does not let me touch anything to unlock the device or open applications.

First, try to reset the system. This could not be possible, but if you are able to, start with this. To Reset the system you will enter System Settings and then Backup & Reset and you can press on Reset and the system will be resetting to the initial state.

If you are unable to perform this 'soft reset'. you may want to try a hard reset. WARNING: performing a hard reset wipes all data and sets the tablet back to default system setting. To perform a hard reset, push the up & down volume buttons and power button at the same time. When the reset screen comes up, use the volume buttons to choose 'wipe cache'. Then select 'yes', then 'wipe data factory' and 'yes'. After this has all finished, reboot the device.

If the problem still occurs, contact Lenovo support at https://forums.lenovo.com.

I tried this (thanks for the instructions, hence the upvote) but it didn't make any difference; it now sticks at the 'set location' screen which needs touch to proceed.

Did you drop it. the digitizer top glass might be cracked and broken or the cable could have been damaged or unplugged. I have a crack screen and touch still works. There's an app called phone tester but u need to be able to touch. Unless there's USB mouse support?

Just repaired a Lenovo A2 charging port. After the repair when I got the tablet to charge the touch would not work. I held the power button down for about 15 seconds until it powered off. A minute later I turned it on and it reset itself and the screen started working. I knew their was nothing wrong with the touch screen because the cable was not damaged and after testing the connector on the board for current I got a reading over 2.0 volts. Hope this helps.

Touch Problems on TAB? ? immediate solution is to plug in a computer mouse using OTG Adapter. Mine Lenove Tab sometimes does not sense touch. After plugging in the mouse you can control , take backup or reset the tab.

Best wishes!

Vishal, I plugged the tablet into the computer and was able to access the data. What needs to be done after the tablet is plugged in to the computer? I could already reset the tablet using the power-on function (hold volume up while pressing power key). Resetting tablet did not restore screen function.

So once I plug into computer and have access... what then? Thanks.
