Old tablet, probably needs new battery, dont know which tablet this is
Keep getting message that Google has stopped. Old tablet. Will a new battery fix this?
Do you still get the message if you run the tablet with the charger connected and switched on?
If you can enter the tablet OK, go to Apps > Settings > System > About tablet. You should find the model information of the tablet listed there.
Try starting the tablet in safe mode (hopefully this procedure will work on your model) and check if the problem is still there.
If it doesn’t show anymore then a downloaded app is the cause of the problem. The trick is to find out which one.
Let us know how you got on and we’’ll proceed from there.
