Apple 5s App Store can't install software how to solve

Problem failure

Can not install the new app. Download the software, the App Store shows "open", but the program can not open, the desktop does not have a program icon, from the "set a general usage" in the program icon, but no program name. What's the situation? Now almost all new installed programs are like this, the installed program can be updated normally. The first discovery of this problem is found a commonly used software icon disappeared, thought is mistakenly deleted, the download directly show "Open", the description has been installed, only to set a dosage to find the program after deletion, but no longer installed, and then other new programs are like this. I tried to log off my account, reboot, reset My network settings, and I did not resolve it.

Problem Solving method

You can do this in several ways:
First, click Settings-General-access restrictions, first turn off the "Install application" option, and then open, the background application refresh also turned off, testing.

Second, click Set-General-description file, go to the point "remove", test (if no "description file" option is not valid).
Third, restart the machine, the method is to hold down the home key + open the key, to the device appears logo let go.

Four, mobile phone connected to the computer with itunes installation update, to see if it can be successful.
Five, if not resolved, it is recommended to enter the DFU mode recovery device (remember to back up).
