Dear Friends, I am here to say that my tablet named Allwinner Tablet A31s Android 4.2.2, is not working properly. When I pressed on the power button it came, but it was stuck on the startup screen. Even the homescreen was not displaying. It is stuck there. When I am pressing the power button, it shuts down and when I am power oning again the same thing will happen. Can you suggest me some ideas ?
