The phone still has a lot of memory space, but when I use Bluetooth to receive files, it says there is insufficient storage space and cannot be transferred. What's going on? How can it be done?

After Bluetooth transmits things, the things you receive are stored in the SMS folder. The reason you mentioned is because the way you save SMS messages is to store them in the memory of the mobile phone. Generally, the memory of mobile phones is relatively small. If the thing you receive is larger than the body memory, the reception will fail due to insufficient storage space. All you need to do is to change the storage method to memory card in the SMS settings.

In addition, if you save it to another folder on the memory card (memory card) after receiving it, then delete the files received in the text message, and then change the original storage method from the memory card back to the phone memory. , because there will be a slight delay when using a memory card for text messages, and the speed is not faster than the memory that comes with the phone.
