I’m using MIUI global developer ROM 6.4.14 (Lollipop) from last two days. I’m constantly having an issue with it. The gallery app doesn’t show the photos that are stored in external SD card > DCIM > Camera folder. Tried to move that camera folder to pc, then clicked some photos (saved to ext. SD card) and then moved those photos from pc to mobile. After that, gallery app showed all those photos for a while but after a reboot, it again stopped showing all those photos from ext SD card camera folder.Source: miui.com
