How to recover missing photos from Android gallery?

After the Android update, if the photos are missing, take out the flash card and put it in place, after a couple of seconds the photos should appear in the gallery! It's that simple!

There are at least two ways to return disappeared photos from the Android gallery. With the help of a PC and auxiliary programs. Or using Android apps. This is possible due to the fact that drives do not completely delete information about the erased file. In other words, after deleting, the device says that it does not see the file, but wants to write a new one in its place. Until new information is recorded, it is not very difficult to resurrect the missing photos. To do this, you can use one of the free utilities that you can easily find in a search engine.

Open Settings in any way possible.
Go to General Settings and look for Applications or Application Manager.
Go to the "All" tab or something similar, and find the "Gallery" application among the system ones. Tap on it to go to the details page.
Look for the "Cache" mark on the page. Depending on the number of images on the device, the cache can be from 100 MB to 2 GB or more. Click the "Clear" button. Then - "Clear data".
After clearing the gallery cache, go back to the general list of applications in the manager and look for “Media Storage”. Go to the properties page of this application, and also clear its cache and data.
Restart your smartphone or tablet.
