Contrary to the iPhone 6P, which had Touch controller IC's on the logic board which had a tendency to die when the phone is repeatedly flexed (i.e. Touch Disease), the iPhone 6S series (6S / 6S+), has all of the digital logic to control touch functionality built into the screen assembly.
So unless there is a power problem (still possible), the most likely solution to your problem is to replace the screen assembly. If your phone is under warranty, then you should return it to Apple for repair. If it is not, then you should look up some well reviewed, local third-party repair shops. they can put a new screen in to see if that solves your problem.
If you want to try it yourself, the you can get a replacement screen here and a repair guide here.

Yes. But only the screen i took it to apple the first time, but this time i took it back to see if they can fix the Situation they told me they can't work phones that have aftermarket parts Which by the way i had order a battery from fixit.com so there was no way they could see if it was the screen or the phone
Hey so Yesterday i took that Screen off that i thought didn't work Cause it didn't respond. so i tested that screen on My sisters iPhone to see if it was my iPhone or My screen. so it was not my screen cause it worked.......So whats really wrong with my phone if its not the screen?
