Home button stuck and won't push in

I just replaced a screen for an indivdual on his 6s, everything went well. Aside for the home button being stuck and unable to press in.

I had this issue on a phone I bought of a friend and it turned out the little metal dot on the bracket had broken off and i used a new home button bracket and it fixed the problem.

I figured this may of been my isssue but the home button bracket looked fine, took the home button of his phone a couple times to see if i could figure it out and no luck, i ended up putting the screen on still and just turning on assistive touch for him.. Charged him 20$ less for the repair unfortunately. I could click the home button a bit like if i pressed decently hard which I knew couldn't be right.. It was basically stuck in place.

I read someone say on another post its an issue with third party screens and the glass or something, and if i loosen the screws a little bit it may fix the problem.

Is there any info some of you may have? Those who have experienced anything similar on an iphone 6s repair.

Thank you !
