Re: Why does my keypads keeps popping off and on

Welcome to Android Central! This is probably due to the phone having faulty firmware and/or hardware, which would not be surprising for a no-name or off-brand device direct from China. Quality control was likely minimal, and support is probably nonexistent.

Did the phone come with Google Play Store preinstalled? If not and you had to install it yourself, the phone is not certified for Google Play. In this case, Google Play Store may not function correctly. You could try installing Amazon Appstore, but if that also doesn't work, you may just be limited to the smaller obscure app store that the phone probably came with.

As for your various issues, the main thing I would suggest is a factory reset. Make sure you're starting with a clean slate, and don't allow any app to reinstall automatically. If the phone works ok, then start reinstalling apps one by one, and see if problems start up again.
