I go on Youtube. It says I have to update. I go to the Play Store and click update and it says error 927 in a pop up box. What do I do?
There are a few tricks to bypass this error on your phone:
Remove Google Play updates using Settings > Applications Manager > All > Google Play * > Uninstall Updates.
Remove Google accounts, and add a fresh account. Reboot phone after this procedure.
Clear the cache of the Google Play Store. Tap on the icon then drag it to App Info and use Clear Cache.
Switch to another WiFi network, because the one you are using might prevent downloading from Google's servers.
