What should I do if I can't open the iphone6 SMS and flash back?

There are several possible reasons for this situation.

First, it may be because the mobile phone has not been turned off for a long time and the system is wrong. You can try to restart your phone.

Second, if the problem still occurs after restarting the phone, you can use some third-party auxiliary tools to repair the iPhone6 flashback. The specific steps are as follows:

1. First connect the computer with the original data cable of iPhone6. Take the PP assistant as an example, open the PP assistant, wait for the successful connection with the iPhone, and click "iPhone" in the left pane;

2. Then in the right pane, click the "Click Repair" function;

3. Then wait for the software to fix the flashback problem of the iPhone, and then you will be prompted to fix the flashback successfully. Click "OK".

In addition, it is recommended to download the software in the App Store, and generally there will be no flashback and no repair problems. After all, the App Store is a self-contained app store in the iOS system, which is more compatible.
