Under normal circumstances, the iPhone can't download software in the App Store, which is caused by network reasons. Because Apple's App Store app store server is abroad, the software can't be downloaded when the network is not smooth.

So if we want to solve the problem of not downloading, we have to start with the network. Generally, the speed of wireless network is fixed, but we can start with the network DNS service address. The quality of this DNS service address will directly affect the speed of internet access.

& gt03

The next thing to do is to manually specify a DNS address, so that the iPhone can access the App Store server smoothly, which is like bypassing the traffic jam and finding a new route to reach the destination when there is traffic jam.

& gt04

First, please open the settings application on Apple iPhone, as shown in the figure.

& gt05

Next, in the setting list, please click on the column of wireless LAN, as shown in the figure.

& gt06

Then please find the currently connected wireless network in the wireless LAN list, and then click the information icon on the right to enter the wireless network and property setting interface.

& gt07

Next, in the properties of wireless network, click the DNS column under the IP address bar, delete the original DNS address first, and then manually enter the address11114.

& gt08

If there is no accident, you should be able to download the application software normally by opening the App Store in the future. If it still doesn't work, there is an alternate DNS address, 8.8.8.8. You can try it.
