First, the IOS7 system version has been improved, some of the parameters of the IOS6 system have been modified, resulting in the developer for IOS6 or lower version of the system is not fully compatible to iOS7.
The solution in this case is to wait for the developer to upgrade the IOS7 system development package, after the release of the IOS7 official version, I believe that very developers will also update their own products, as long as you upgrade the corresponding program can be resolved.
Second, there are too many open applications, the iphone memory capacity overload causes the program to flash back.
The workaround in this case is to close the application from the background.
Third, if the background application is closed, after reopening or flashing, this is the system inside the cache too much.
The solution in this case is to reboot the iphone.
Four, use 91 assistants to repair the flash back function
Connect iOS device to computer, then turn on PC 91 assistant, click Software Game-no jailbreak or user software-software flash-back repair
