Re: Samsungs 5 help
Welcome to Android Central! You mean your microSD card, not the SIM--the latter is what allows your phone to connect to your carrier's network.
Using My Files, can you see that the photo files are still on the card? If they're physically there, but not in your Gallery app, then there are a couple of things to try:
1. Go to the App Manager, select Gallery, and Clear Cache/Clear Data, then Force Stop. Now open Gallery again and wait a few seconds for the database to rebuild. Do you see the photos now?
2. If not, go to
Settings>Storage and Unmount the SD card. Then tap Mount, and wait a few seconds. Go back to Gallery and see if the Photos are there. What you're trying to do is to make the system's Media Scanner rescan the SD card and look for photos to place in the Gallery database
3. You can also try the
Rescan Media app, although I'm not sure how compatible it is, considering it was last updated in 2011.
