I just replaced the screen on my iPhone 6s, wasn’t sure how you put the screen back on after finishing everything and it feels like it’s not in properly in some places? The screen also doesnt have a smooth taper to the body, making me feel I’ve not put it in correctly. The screen looks fine and the phone is functional other than that.

There is actually a simple reason here you could’ve bought the wrong type of phone screen or you might’ve broken a clip(s) that hold the screen in place so check the phone if there are any broken clips. If yes you may need to get those replaced if no than you could take a hair dryer and blow on the edges of the phone and try pushing in carefully since heating it will make the glue a little ore flexible good luck!
