As per the article (link given below) NiceLock is the alternate option to Good Lock in regions where the latter app is not supported, specifically the Middle East.If you do download NiceLock please leave a comment which would help others looking into...
Can anyone suggest if it's possible to get Good Lock on Note 8 in the Middle East...can't seem to find it in the Samsung Store. Or another alternate. Cheers
Create an album in your phone gallery using SD card option as storage...then move the files from the internal album into the SD album. That's how I am doing it on note 8.
