What should I do when the software crash? How can I fix the software crash?

First problem

1. As shown in the following figure, the software downloaded using the synchronization assistant sometimes has an Apple ID and password input box,

2. Solution: connect the mobile phone to the computer, and then enable the synchronization assistant "genuine authorization" once:

 

Second problem

1) in this way, we can find [installed] in the synchronization assistant and click to enter

2) then we will see the list of installed software. We can find the software to crash and click [download again]

3) after the download is complete, click Download management in the lower-right corner of the assistant, find the downloaded application in the downloaded application list, and click install to fix the crash.

Experience Sharing: some software we have used for a long time will find the crash problem. I often encounter this problem when I use iphone4s, but it will be okay the next day. I guess this is a mobile phone memory problem, however, I still cannot solve some software crash problems by using related tools. It is estimated that the software's own problems will become automatically ready the next day, and there is no solution for this.
