My tablet shows "insufficient space" error message whenever I install new apps (Clean Master) although it has enough storage!
- Default write disk: phone storage
- Internal storage 3.87GB: available 385MB
- Phone storage 27.73GB: available 18.80GB
- Android 5.1
Note: I tried to fix this issue by using SD Card and set "Default write disk" to it but it didn't fix the problem.
