I have transferred all the files from the DCIM folder in internal storage to SD card. Still it has data above 3GB and files above 4000.
Have you setup the SD card as 'Expand internal storage' or 'External storage' ?
If you have Expanded internal storage, It would display the same in Settings > Storage > Internal Shared storage > Photos & Video.
OR If it is as external storage, You might want to try the below steps - Use a File explorer application on your phone and verify if you have copied / Cut the files from the internal storage location - DCIM.On deleting the DCIM folder, If you start the Camera app with default storage location as Internal storage, the folder will be created again.
