Re: why i can't download google play games its error 920
Apparently many people have had success by doing this.
Remember, nothing is always perfectly safe, so back up your data before trying anything.
Go to Settings
Apps
Open the All tab
Click Google Play Store
Now clear cache and clear data
After that, uninstall Google Play Store updates (just the updates)
Restart the phone
Open Google Play Store and install the app you wanted to download.
