Upgrade Stopped Due To An Error Lg L5
When Android shows the 'Insufficient Storage Available' error
- Open the Settings app, tap Apps, Applications, or Applications Manager option. (Applications Manager might be an option after either Apps or Applications.)
- Scroll sideways to the Downloaded section. You'll see a list of all apps and how much storage space they're taking.
- Tap the Menu or More button and choose Sort By Size to arrange the apps by which take the most storage.
- Tap an app to see how much storage it is taking, both for the app and its data (the Storage section) and for its cache (the Cache section).
- Tap Clear Cache to remove its cache and free up that space. You could also tap Clear data, but that removes your files, which is probably a bad idea.
- Repeat for each app.
- Open the Settings app, tap Storage (it should be in the System tab or section). You'll see how much storage is used, with details for cached data broken out.
- Tap Cached Data. In the confirmation form that appears, tap Delete to free up that cache for working space, or tap Cancel to leave the cache alone.
When iOS won't install an OS update for lack of space
- Tap and hold on one in the home screen; the app icons will start wiggling.
- Tap the X icon on each app you want to remove, then tap OK in the confirmation form. The app and all its files and other data are removed.
- Press the Home button when done. The wiggling will stop.
- Open the Settings app.
- Tap General, then tap Usage.
- In the Usage screen, tap Manage Storage and wait a few seconds for a list of apps and their storage usage to appear.
- If you see the > icon to the right of an app name, you can delete its files. Tap > to open a screen showing those files.
- Tap Edit in the upper right, then tap the Delete icon (the red circle with a minus sign in it) for each file you want to delete. Keep in mind that if you hadn't backed up that file to iTunes, it's likely gone -- iCloud Backup doesn't preserve apps' files, though iTunes purchases like videos and e-books can be redownloaded at no charge.
- Tap Done when done.
