The Samsung I509 phone prompts that the message memory is full and cannot receive the message.

In this case, it is recommended to uninstall the third-party application software to view, it may be caused by the compatibility of the application software and the mobile phone, if this operation is still caused by the mobile phone, you need to restore the mobile phone to factory settings, please back up the important data stored on the mobile phone in advance before restoring the factory settings, such as: **book, short message, **, **file, etc., to prevent the data on the mobile phone from being lost and cannot be retrieved.

The phone cannot receive SMS MMS, indicating that the memory is insufficient, it is recommended to clean up the phone memory as follows:

5.Uninstall third-party software that you don't use often.

Install an Android Optimizer and move all the software that can be moved to the memory card. If that doesn't work, try restoring factory settings, flashing, etc.

Check the internal storage space, most of the time it is because the internal storage space is too small, the internal storage space of this phone is only about 20 to 30m or so, uninstall the program installed into the internal space, and you're done! Remember to add extra points when you're done!

Try doing a factory reset, but back up important information.

You may not receive an SMS or verification code for the following reasons:

1. You can check whether the mailbox is full, and if so, please delete part of the information;

2. If you still can't receive it after deletion, you can change the phone or change the card to test whether it is a hardware factor;

3. After ruling out the above reasons, you can try to test whether it can be received at another location to see if it is the cause of weak local signal.
