So I decided to fix it.
- Heat up the screen with a heat gun on low or a hair dryer on high. Make sure you keep on moving the heat source in figure 8 and keep the heat source around 10 inches away from the screen. Do this for around 5 minutes, the phone needs to be hot, uncomfortable to hold, but still you should be able to hold it with your bare hands.
- Protect the screen and back of the phone. Clamp the top of the screen. Wait for the phone to cool. Release the clamps.
This worked wonderfully for me, the screen is now flush with the body, I can't feel it when I run my finger on the edge between the screen and the body.
