I have a Samsung Tablet E 9.5 inch screen

[AC Question]

When I watch videos I have lag. All videos lag. When I take my own videos they lag too. I do not know much about this. How can I fix this? I am computer illiterate.

Welcome to Android Central! Is this only for locally saved videos, or for streaming videos as well? Does the lag persist in Safe Mode? Access Safe Mode - Samsung Galaxy Tab E
