How do you fix gallery and audio issues on htc desire 626s?


AC Question

Hi All,
I've tried just about everything from connecting my phone to the PC and transferring files; renaming .nomedia files; downloading suggested apps; made more space and still unable to view my gallery pictures/videos on phone and/or SD card. It shows as an error triangle. Please provide advice to help resolve this matter without me having to do a factory reset...last resort.
~Thanks in advance
