Samsung note3 suddenly can't receive any short messages, so try to solve it.

According to your description, I suggest you:

1. Clean up the read call records and text messages in time.

2. Clear the Internet records of mobile phones: browser-menu key-settings-privacy security (privacy)-clear cache, clear history, etc.

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

1). For Android 2.3/4.0/4. 1 system: My Files-All Files -sdcard0- Find the folder to be moved-Press and hold-Move to-Return to the outside _sd- Click "Move here".

2). If it is above Android 4.2: Application-My Files-All Files-Device Storage-Find the folder to be moved and open it-Menu button-Select All-Click the three column icons-Move, return to the parent directory, click the SD memory card-select the related folder (or create a new folder)-and move it here.

Note: For Android 2.2 and earlier versions (some Android 2.3 systems do not support the built-in hard disk), multimedia files are stored in the external SD card by default.

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

5. Uninstall third-party software that is not commonly used.
