There is not enough storage space on the display of the mobile phone, so I can't even receive short messages. What happened?

According to your description, the mobile phone prompts that the memory is full/insufficient or needs to optimize the memory use. I suggest you:

1. Press and hold the home key, open the ram manager, clean up the running application, and release the program memory.

2. Uninstall the self-installed application.

3. Clear the mobile phone's Internet cache: browser-menu key-settings-privacy security-clear the cache and clear the history.

4. If it is a picture/video shot by a camera, you can set the storage path to an external SD card in advance. Operation: Open the camera-Settings-Memory-Memory Card.

5. Clear the recorded incoming calls, text messages, etc.

6. Move the multimedia files to the external SD card. Operation:

Apply-My Files-All Files-Device Storage-Find the folder to be moved and open it-Menu key-Select All-Click three bar icons-Move, return to the parent directory, click SD memory card-Select related folders (or create new folders)-Move here.

7. Back up the important data in the mobile phone and restore the factory settings.

If there are still problems through the above methods, please bring the purchase invoice, maintenance card and machine to Samsung service center, and the engineer will check and deal with the machine.
