Slightly bulging screen and clicking sound in corners of phone

I recently got a 3rd party repair of my iPhone screen after dropping it as well as a screen protector, however, I noticed that the bottom right of my phone is slightly elevated. If I push down on this corner it can flex slightly back into a more appropriate position. When I apply pressure to the top left and right of the screen it flexes slightly and makes a clicking noise.

Here are the measurements of the four corners of my phone I made with a caliper:

Top left (clicking): 8.62mm

Top right (clicking): 8.67mm

Bottom left (no problems): 8.56mm

Bottom right (bulging): 9.06mm

(These measurements are all with a screen protector)

This has been bothering me recently because of the slight difference in the bottom right corner raises it beyond the barrier of my phone case and has been scratched and cracked because of this. What steps should I take to fix this problem?
