How to fix ‘Unable to save screenshot, USB storage may be in use’ error

If you receive the following message:
Unable to save screenshot, USB storage may be in use.

Then follow these steps to fix the error:

1. Open File Manager. If that is unavailable, ES File manager can be downloaded instead via the Play Store.

2. Select Show Hidden Files/Folders. You should be able to see a folder named Pictures.

3. Then, in the same screen, locate the Screenshots folder. If you can’t find it, create a new folder with the name Screenshots

4. After making the folder, restart your device. You should be able to take screenshots now.

5. If your screenshot still doesn’t save, follow the same steps above (1-3) but use instead of doing this for the Pictures folder, try it for the DCIM folder.
