Any tape or adhesive for touchscreen?

Hi

So, I got my LCD and Touchscreen replaced today. The mechanic was like a beginner. He replaced it and works fine. Touch is perfectly fine. There is small bug left which is disturbing me. Go thrugh attached pics of my mobile first. The touchscreen is not properly installed it seems. On one side, it is coming up. Shall I use some tape or adhesive. Any help please..?

Please see all 3 images one from each side. A little press around home button is required.
