This will prevent Google Currents from constantly downloading and writing data in the background. If your Nexus 7 is too slow or isn’t responding to touch events properly, open the Currents app, go into its Settings screen, and disable the Syncing option. Disable Currents Background Sync & Other Background AppsĪs we noted in our Nexus 7 troubleshooting guide, Google Currents syncing is a notorious cause of lag on the Nexus 7. If you want to test whether this is actually doing anything, you can run the Androbench storage benchmark app before and after to test your NAND storage write speeds and see if they improve. If your tablet isn’t rooted, you’ll need to use Forever Gone, which will fill your storage up with empty files and then delete them, causing Android to issue the TRIM command on the storage. This app is a frontend to the fstrim utility, and it will TRIM your empty storage, fixing this problem. To do this yourself, you can try the LagFix app from Google Play (it requires root). However, this update does nothing to fix existing sectors that should have been TRIMMed in the past, but were not.
