If you're seeing an "Insufficient storage available" message on your Android, chances are that you've used up most of your device's available memory. To rectify this, you'll need to make some space by deleting apps and/or media; you can also add external storage, such as a Micro SD card, to your phone. In some cases, however, this error shows up even when you have plenty of space. If this is the case, you can restart your phone, reset your apps' caches, or reset the Google Play Store to resolve this issue. Or if you're using ZenFone you may try this troubleshooting:
Follow methods below for troubleshooting:
- Uninstall apps that are not often used: Settings>Apps> (Select an app you want to remove) Uninstall.
