Tablet overheats during general use, charging or while not in use.
Too many actions at once
You may be overworking your tablet. If you are using your tablet in a cool, dry environment and you are not charging your tablet while in use then your tablet should not be overheating. If it is overheating in these situations you may be doing too many things at once. Try closing some Internet tabs and closing apps not in use.
Tablet in hot environment
Your tablet may be in an environment that is too hot. Electronics are meant to be used in cool, dry environments. If you are not doing too many things on your tablet at once and you are not charging your tablet while in use than you might need to use your tablet in a cooler location.
Using charger while in use
You are using the charger while the tablet is in use. It is not recommended that you use your tablet while you are charging it. Aside from making it take longer for your tablet to charge, and possibly degrading your battery, your tablet may overheat if you use it while it is charging. Try letting your tablet charge while not in use.
