New displays touch is not working.

I had bought a while ago a refurbished OEM display for my old iPhone XR. Problem is that new screens touch is not working even though it turns on and shows everything as it should. I was reading long ago something about multiple display manufacturers and that there was an issue that one model was not working properly with others display. I think I have this issue but I have no idea how to confirm as I don't know how to check which model I have nor what display model it is (probably have serials inside though). I am thinking of buying a JH display now because they are cheaper and apparently work with every model, seems also somewhat close to original (hopefully). What I want to know if this is not some phone issue that needs to be fixed or it is just the model problem.

Answer this question I have this problem too

Is this a good question?

I wouldn't put too much stock in internet reports about incompatible screens. You can reasonably assume that if you buy a screen for an iPhone XR, that screen will work on any iPhone XR; if it doesn't it's defective and should be returned for replacement or refund.

As Jesse already pointed out, you should probably try your old screen and verify that the touchscreen works on it. If it does, that points squarely at the new screen's digitizer being faulty, whereupon you should contact the seller about it being covered under warranty.

But before you go quite that far, do as Jesse suggested and get yourself a magnifying glass and check the pins on the digitizer's connector - both the one on the motherboard and the one on the cable. Look for any bent or broken pins; if you find any that are bent they can frequently be straightened out with a pair of fine tip tweezers. Once you're satisfied the connectors look okay, clean them with 90% or higher concentration of isopropyl alcohol, then reconnect and retest.

If it still fails after that, then it's time to pursue your warranty and see about getting a replacement screen.

You could inspect the flex cables and connectors for the display. Make sure they're free of any tears or harsh creases or damage. If the old screen still works, you could try that just to be sure.
