Hi,
I after I replaced my screen at a mechanist at mall, he screen doesn't work properly so I ordered replacement screen from iFixit. After I installed iFixit's screen, it also risen too much and I had to press hard on the screen to activate 3D Touch. I talked with a customer representative and got a replacement, but it has the same problem. I compared my phone with my friend's iPhone 7 plus and significantly feel the screen is risen too much on the right sight. I removed all the waterproof adhesive tape around edges but it doesn't help.
