Gmail stuck updating offline disk cache
Your phone stores a wealth of information such as apps you download, websites you visit, and searches you perform.
Clearing out the caches and data for apps will clear out this information, however, you must clear the cache and data for each app separately.
Sync Center allows you to keep information in sync between your computer and Files stored in folders on network servers.
These are called offline files because you can access them even when your computer or the server is not connected to the network.
Some apps with Google Drive integration store files on your device to improve performance and allow you to use the apps offline.To clear the cache or data for a specific app, touch the app name in the list.On the “App info” screen, you can clear the data for the app by touching the “Clear data” button in the “Storage” section.RELATED: A dialog box displays warning you that all of this app’s data will be deleted permanently.NOTE: This is not recommended unless you want to reset an app or are uninstalling an app.
If you are ready to delete these files, touch “OK.” This can be useful if you’re having trouble with files syncing to Google Drive.
