1. Power off the tablet
2. Boot into recovery by holding down "volume down" whilst holding down the power key.
3. Keep volume down held until a menu entitled "Android System Recovery <3e>" appears.
4. Use the volume up/down keys to navigate the menu. When "touch calibration" is highlighted, press the power key to select it.
5. Put the tablet down and don't touch the screen.
6. When calibration is finished, the tablet will power off
7. Power the tablet back on again.
OR
You can improve the touch delay by going to settings > language and inputs > google keyboard settings and uncheck all box that you see in googgle keyboards's setting (this includes advance settings). This is only temporary improvement but the touch delay will still return but not often as before. I believe this is a software issue. Only lenovo with a latest update could fix this
