I had the same problem...The problem is with the Google Play Store app that was updated sometime in February 2017. Your tablet will freeze at times, and apps will not work/open correctly, and go to a black screen when you try to open them (Netflix etc) TO FIX THIS SIMPLY: Try resetting the tablet to factory setting, and do not log/sign into the Google Play Store when you are first setting it up. If you log into it, & update, it will mess your tablet up again, & you will have to start over - DO NOT DOWNLOAD ANY APPS FROM THE UPDATED PLAY STORE AT THIS TIME - Any apps that you want or need, can be downloaded from the internet or from an alternative app store that you can also download. Just search the internet for any specific app or Android APK by typing the name in Like "Netflix APK downdoad" or "Avast Mobile Security APK", games etc. You can down load pretty much anything that you can get from Google Play Store if you find an alternative store HOPE THIS HELPS - THIS SHOULD FIX YOUR PROBLEM :)
