You open this article, therefore, I believe you know why I’m writing an article with a title which can’t be understood by users of iPhone 8/8p/and versions before. It always says “Double Click to Install” on the screen, but click what? You will find the answer here.
How to install apps on iPhone X?
If you double tap the screen after seeing the notification, then the download won’t continue. In the computing world, click is used to denote the action of pressing a mouse button. On smartphones, it also means to operate a physical button or switch on the device, something that could make a “Click” sound, even if it doesn’t. Therefore, when you want to download an app on iPhone X:
1. Open App Store
2. Search name of the app you want to download
3. Tap the button GET, and see “Double Click to Instal”
4. Double click the Side button
5. Enable your iPhone X to scan your face for FaceID verification Some Advantages of Face ID Over Touch ID
6. Automatically start to download the app
Still can’t download any app
You know the correct operation, but you still can’t download an app. Maybe there are some problems.
Close And Reopen The App Store
It may be because of a software glitch within the App Store. Therefore, close and reopen may fix the problem.
1. Swiping up from the bottom to the center of the display until you see the menu of the apps currently open on your iPhone X
2. Then press down slightly harder until the red minus button on the top left appeared
3. Tap minus button to close the app or swipe up the app and off of the screen to close.
4. Tap the app icon to reopen it.
