Let's take a look at a slow chart on the App Store.
App Store Cotton doesn't even have it.
1, cleaning up the cache
You can empty the cache by clicking any of the buttons in the bottom five buttons 10 times in a row in the App Store.
Another 10 consecutive clicks of the same button after the phone will be white screen a few seconds are normal phenomenon oh, screen a few seconds after it will automatically return to the App Store home page
2. Network Reason
If the NIC is not connected, you can turn off the App Store page and disconnect the WiFi, then reconnect the WiFi and open the App Store for a try.
3, change your network DNS, if it is WiFi can be changed DNS.
Apple Exchange DNS
The first step: Open the Settings application.
Step two: Click on "Wireless LAN" to enter the Wi-Fi list and select the Wi-Fi network available on the connection.
Step three: After connecting to the available Wi-Fi network, then click the "Show Info" button (letter "i") to the right of the Wi-Fi network name.
Fourth step: Scroll down in the details section of the Wi-Fi network to find the "dns" option section.
Step Fifth: Next, enter the DNS values you want to change on the keyboard that pops up. In this example we use the 8.8.8.8 provided by Google.
Additional suggestion: If you think it is slow to open the App Store, you can set DNS to 8.8.8.8,4.4.4.4
