I just did a factory reset on my Acer Tab 8, and now when I try to reinstall the apps which I had previously installed on my tablet, Google Play says my device is not compatible with any of them. They were on it before I did the factory reset. Does anyone know what I need to do to solve this problem? I've tried doing another factory reset but with the same results. The only apps I'm allowed to use are the preinstalled ones and even if I check the Google Play store for those, I still get a "your device is not compatible" message. Thanks!
