Corrupt Storage – If your phone or SD card storage is corrupted, you will not be able to install applications on it.

Restart phone when this error occurs. Remove the battery, SIM, SD card – insert again and reboot device.
If SD card is corrupt, format or replace SD card.
Reset app permissions. Navigate to Settings – Apps and reset app preferences.
If you’ve changed the default app installation locations, change back to automatic and let system decide in case there is no storage space.
If storage is full, free up spaces by uninstalling irrelevant apps and deleting junk files.
Go to settings and allow installation of applications from unknown sources.
If all fails you will need to do a hard reset and restore factory settings, before doing this make sure to back-up all files somewhere else.
