Many Google Nexus 7 users reported on sites like XDA-Developers and Reddit major lag issues after being update to Android 4.2, with no official response from Google or Asus. However, one XDA member has found an alleged fix to the bug, which reveals the issue derives from the Google Currents application. The method to resolve the issue is as follows:
- Open your app draw
- Open Google Currents
- Click the three dots in the top right corner of the app
- Tap “settings”
- Uncheck “enable background sync”
- Reboot your Nexus 7
With no official recognition of the bug, it is not certain as to whether or not this is a definitive fix for the issue, but if it helps your Nexus 7 revive its speed let us know in the comments so we can help others work around the fault.
