I have an Android Tablet 10.1 and Google Play is not working on it.
I have had this tablet for about two years now, and about five months ago I rooted it. Shortly after, Google Play kept coming up with errors and stopped working for me.
Being the foolish person I am, I did a factory reset (and I think I un-rooted it) to see if it fixed. It didn't. Now, whenever I try to go on to Google Play, it'll ask for my password and username and after I enter it will say something like "Can't establish reliable connection to server. This could be a temporary problem. Try again or connect to another Wi-Fi network." I have, and that has not helped.
