What should I do if my iphone7 phone flashes back? How can I fix it?

The first type: update the application.

There may be bugs in this version of the software. You can search this software again in the AppStore. If there is a new version, just update it directly.

The second type: reinstall the software

If you don't see the upgraded version of the software in the AppStore according to the first method. Then there is probably something wrong with the software in your hand. You can uninstall or delete the application directly, and then download and install it again.

The third type: insufficient memory

In fact, the operation of the mobile phone needs a certain amount of memory space, so generally we will not run out of memory space in the mobile phone. The more complex the application and operation, the more memory space is needed to run.

If neither method can solve the problem, then the possible running memory space is not enough to open the software. At this time, you can try to delete some files that occupy a large amount of memory in your mobile phone to make room for running. Generally speaking, the above three operations can solve the problem of flashback. But there is another situation that is more troublesome. I hope you won't meet. That's a cell phone malfunction. It cannot be repaired by itself at this time. It is best to send it to Apple's professional organization for inspection and maintenance.
