Iphone prompts that there is not enough memory to receive SMS, but the memory of mobile phone exceeds 7G.

This is the phone running memory RAM is insufficient.

Mobile phone memory is divided into running memory RAM and body storage memory ROM. By default, the mobile phone is stored separately in the order of running memory and body memory, which is why there is still room in the mobile phone memory, but it still means that the memory is insufficient.

When the mobile phone is used for a long time, especially watching videos online, many caches will be generated, and some caches cannot disappear automatically. After a long time, it will form a lot of garbage; Too much software installation will also take up a lot of memory, resulting in insufficient memory RAM of mobile phones. When the memory of the mobile phone is insufficient, the only solution is to clean it up:

(1) Call up the folder where the media is stored, and send photos and videos to the computer;

(2) If you have seen a file with no preservation value, delete it if you want;

(3) clear the memory. Download and install mobile phone management software, such as cheetah cleaner or 9 1 mobile assistant, to further clean up cache, system and uninstall residues.

I hope I can help you, and I hope to adopt it!
