Google search the following: Proscan PLT 9 ROMS

The battery needs replacing

unfortunately batteries go bad too like everything else.
have you tried a different charger?

Try reinstalling the app.

If you haven't done so already, try holding the power button down for a long time (30 seconds+) when you switch it on. If no success, try again but hold down the power button *and* the volume-up button when you switch on.

If the battery is weak, the tablet won't turn ON. Contact the authorized service center. http://electronicshelponline.blogspot.com/

You plug a OTG (USB) keyboard into the OTG socket and it works!

It also gives you more keys than on Googles keyboard.

My proscan tablet is keep freezing and lines are coming across the screen. What can I do
