They have installed and uninstalled lots of different games on here with no memory issues or glitches. Music works with my cricut sim card and hooks upgrade to wi fi and my mobile phone’s hot spot for trips in the car. The camera isn’t the best as photos are pretty grainy, but it’s not really necessary for us to have good quality on these. It was easy to find cases for these. My husband has installed two apps of our store security. Cameras and resolution is just perfect.
