"How do I keep my charger from coming out?"에 답변You should hear and feel a little click when the charger seats correctly. If you are using a replacement charger you're likely to have this problem over and over. Suggest you find a real Samsung charger for your tablet. They fit and secure far better.
"My tablet and keyboard keep coming apart?"에 답변With the tablet removed from the keyboard, push in the release button at the top of the keyboard (which you push to release the tablet) and look at the small plastic hooks on left and right they need to be both undamaged. Typically some people get frustrated and try to pull the tablet free and that breaks off one of the small hooks. If one is broken, too bad, so sad. If both look the same and one tip or two are not broken off/damaged, then clean the contacts as suggested above and then I suggest you push down evenly when you reinsert the tablet and then sort of gently push down on left and right side top edges of the tablet to make sure the little plastic tips on the holder have best opportunity to hook onto the attaching holes in your tablet's bottom edge.
