Force touch doesn work correct after screen replace

Not all the replacement screens in the aftermarket have good performance on 3d touch. Check this test:

Had the same problem, we changed our first 6s screen (a phone we bought cheap with a broken screen) we bought some 3rd party screens with the lcd attached and the 3d touch would work on the left side of the screen but not the right. We bought this phone just to try.. conclusion.. don't buy 3rd party screens.. take it to apple.. Not until the distributors can master the 3D touch at least.

Hi Guys update I've replaced a few 6S screens and it didn't work so being the perfectionist I think I am lol I went all out and tested it many time still noting finally I made sure the screen was really snug and put sticky tape on top and bottom of screen and Viola 3D Touch started working .. This worked for me hope this of some help to any others with the same issue

I also had this problem , was advised by the seller to make sure that the backlight was fully covered by metal LCD plate (Although what this would have to do with Force Touch I have no idea)

Ended up getting the entire phone replaced ......... but will be following this post with interest!

Ok for everyone following this thread here's an update. I received an email today from one of my suppliers saying the following:-

"iPhone 6S 3D active touch function issue is solved successfully by our factory.Our iPhone 6S screens are with sensitive and perfect 3D active touch function."

iPhone 6s 4.7 inch screens with nice 3D active touch function:

Unit price: $118.1 for AAA made by original lcd, original back light, original flex cables.

iPhone 6s plus 5.5 inch screens with nice 3D active touch function: Unit price: $175.5 for AAA made by original lcd, original back light, original flex cables.

So it looks as though 3rd partys have figured out how to keep 3D Touch / Force Touch working properly now! They said initially with the 6S that the 3D touch was causing big problems but their engineers fixed it.

I guessed (possibly incorrectly) that posting the supplier contact information here wouldn't be allowed for some reason? If that's wrong please let me know!

There is so much that has got to be taken into consideration now with the 6s LCD.

On the iPhone 6/5 etc you can have any grade of OCA (different widths etc) and it wouldn't really matter. Glass thickness could be different but it wouldn't matter. Now 3D touch is here everything needs to be perfect. The glass/oca/polarizer all need to be 1:1 original to maintain 3D Touch.

My opinion is don't ever use a 3rd party LCD on an iPhone 6s.

For everyone who says to bring it to Apple store to replace the screen, apparently you haven't tried this yourself. Latest is that Apple tells everyone their phone is bent or damaged in some way (even though it is not). They say because it is bent they will not replace the screen and that you need to buy a new phone.

Which is why all these other companies are charging more than Apple store, because they know that the Apple store will not replace the screens on your phone anymore.

Touch ID won't work after screen replacements tho .. 3D/Force touch works .. Any suggestion ??

Here i found a usefull article Iphone 6 and 6s

Apple’s iPhone 6s and iPhone 6s Plus are the company’s most successful iPhone launch, with over 13 million sold in its first weekend of sales.

I know the solution you all wrong and missleading poor people ,

The solution: when you replace the screen , make sure that the battery have to be perfectly leveld , you can see that the stick that hold the battery its not only for stickin it in place , its also for levelin the battery in perfect height with the screen , if you have even tiny gap betwen the battery and the screen , the 3d wont work for some parts of the screen , try to level the battery with something ot just buy original white stick strip and place it from scratch ,

Thank you please notice me if it helped you -uri kaspi
