It’s simple to remove apps on iPhone on your home screen. However, iMessage apps aren’t displayed in the primary screen. they live and breathe within the Messages app and the removal of iMessage applications is actually a shady method that not all iPhone users are aware of.
Then, open the Messages app on your iPhone and then create an entirely new message or start an existing conversation (opening any message will work).
Tap the app bar located at the bottom (or just above that keyboard) on the screen of the Messages app. Follow the steps to the right side of the bar of apps until you can see the three dots “More” at the bottom on the listing of applications. Click it to display the IMessage applist screen.
Scroll down and locate the app you want to remove from the Messages app. After that, swipe left on the app to show the delete option to the right of your screen. Click on the Delete button then the application the will be deleted off your iPhone.
It’s the sole method to remove iMessage apps from your iPhone. If an IMessage app is included with an app that is regular on your iPhone and you want to delete it, you might need to remove that app from the homescreen too.
