Now I am planning on getting the replacement screen where you transfer the camera and other parts of your old screen to the new one. There is only one question, does the new screen have the 3D Touch function?
It all depends on the screen. The “cheap” versions prob wont as its cheap for a reason. The better the quality the better the features! I have replaced a TON of screens for iphones, esp 6s/6s plus and have never seen 3D touch NOT work!
