Error pop up message appears when memory is full
■ To read or write to database, at least 8 kilobytes of free space is required on the phone.
When internal memory is full, "storage full" popup and notification appears on the screen.
This is to warn users that insufficient space on internal storage would cause system malfunction.
If users do not free up space and disregard the warning, an error message will continue to pop up.
How to fix
1) Move user's personal files from internal storage to SD card.
Get rid of apps not used for long period of time to free up more than 10MB space on the internal storage.
2) Go to Settings > Storage to check available space on the internal storage.
3) If more than 10MB is secured, reboot the device.
