Samsung Galaxy Tab — Tab e stopped playing videos

I recently got a Samsung tab E for zero dollars whenot I got a Samsung galaxy 8 but along with the other VERY annoying yet tolerable probless with this device ie the Google play store not downloading
The device has stopped playing video, and its not like it just isnt playing video files as another comment said. The device loads a video when streaming but does not play the video. It loads just fine, the WiFi is good, but it just won't play the video, I try pauseing it then hitting play again but nothing happens ( ps if someone could fix the auto correct on this thing that would be nice because putting an ing onto the end of a word does not mean I want the word ingredients added to the end, in fact, try auto correctingredients full words in stead of just whatever can be the start of a word

Well I figured out the problem sorta, apparently thereally is only a problem when the device is connected to my Bluetooth headset ... for some reason
