Cu speranța că te poți descurca în engleză iți dau soluția:
Solution 1
Note: Follow the steps for both Internal and external SD Card
Go to File manager -> Android -> Data -> com.android.gallery3d.
Delete the folder (com.android.gallery3d) in both internal and external SD card.
Go to Settings -> Apps / Application manager -> search for Gallery -> open Gallery and tap on Clear Data.
Switch off your phone and wait for few minutes (say 2-3 min) and then switch on and wait for few minutes.
That's it now. All the images and videos would be showing under Gallery.
Solution 2
Go to the respective folders where images/videos are stored.
Go to Settings > Show hidden file and see if there is a. NOMEDIA file. If there is such file then delete it.
Switch off and switch on the device.
That's it.
Solution 3
If above solutions don't work, then you have to search for apps in Play Store which scans SD Card. SDrescan is good. It's only of 20KB in size. And then scan the memory card using that app.
