KODI not responding

You could try to reinstall Kodi on your box. Maybe a different version.
Kodi is having a lot of issues right now and many addons have shut down. There are lawsuits about it being preinstalled on Android boxes with legally questionable addons.
There are so many variable boxes released under "T95E" names..... which do you have specifically?

A quick google search would indicate the vast majority were released as 8GB/1GB models..... so chances are good your system resources are being used elsewhere.

Try "force stop" for any apps/programs running that you don't need.
