This is the phone running memory RAM is insufficient.

Mobile phone memory is generally divided into running memory RAM (solidified on the main board of the mobile phone and cannot be expanded), body storage memory ROM and extended memory SD card. By default, the mobile phone is stored separately in the order of running memory and body memory, but it needs to be manually set to be stored on the SD card, which is why there is still room in the mobile phone memory, but it still indicates that the memory is insufficient.

Mobile phones have been used for a long time, especially iQiyi, Q Q and WeChat. When watching movies and small videos online, many caches will be stored in the mobile phone and cannot disappear automatically. Over time, a lot of rubbish will be formed. Too much software installation will also take up a lot of memory, resulting in insufficient memory in mobile phones. The only solution is to clean it up:

(1) Download and install mobile phone management software, such as Cheetah Cleanup Master or 9 1 Mobile Assistant, to further clean up cache, system and uninstall residues;

(2) Unused software needs to be uninstalled and cleaned to release memory. You can release memory space by "moving software to SD card" through 9 1 mobile assistant or cheetah cleaner;

(3) Set the mobile phone browser, and change the download location to SD card;

(4) Enter the photographing state, enter the camera settings in the photographing interface, and set the photo storage location as "SD card".

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