Why is my tablet being stupid?
I charged my samsung galaxy tab 2 7.0 all the way, then when i go on it it subtracts my % by alot. Do you know what i could do.
Frank, you need to try a factory reset. Remember, a factory reset will erase all data and apps from the tablet! Back up any important data (Pictures, music, etc.) to your PC before reseting. Also, get an app called "Malwarebytes" from the play store. It will scan for malware and eliminate it. Do that first. Hope this helps!
Have you ever tried restrating it? Find a good charger, some chargers don't work like on my s3
Make sure you are using a Samsung official charger that provides enough Amps to the tablets. Tablets draw more power than phones do. It may also have a bad charge port. If the port is loose or damaged it can have an inconsistent connection and will charge and then stop.
