Problems setting up Touch ID

My friend's finger print suddenly stopped working on her iPhone 6S. When she went to redo it, voiceover kept saying, "make sure your finger is covering the entire home button. She did a few scans and then it told her to try again. She repeated these steps with no luck. Any suggestions?

Hello. Sorry for hearing that, but I had the same problem using an iphone 5 S. Iphone 5 S and SE are using the same generation sensor so after a while it seems that it is mal functioning. I was able to solve it but it tooks some tries. I was lucky and a few monts after that problem I changed the phone.

Hi,
Touch id is very finicky in how it works. If your finger is wet in any way, or is in gloves, it won't work. If your fingers sweat, touch id will not work and you'll run into this. I've switched to face id and will be sticking with it for the future as it is much better than touch id. However, in your friends case, either her fingers are wet, or the touch id sensor built into the home button is dammaged and they'll have to replace the home assembly. Sorry i can't be of more help than this.

My friend's 6S is used. I had this issue when I had my 7 and I was able to finally get my finger print to work. What should she do? She doesn't have a lot of money to replace the home stuff.

I've had this issue a couple of times. Substances like sunscreen and bug spray, when transfered to the home button because of finger contact, render Touch ID very inconsistent and disfunctional most of the time. Tell your friend to pour some water on a tissue, squeeze out the moisture and give her phone's home button a wipe-down. Oh, and cleaning the screen isn't such a bad idea either, since phone screens are VERY dirty from constant usage.

On my 6S, if my fingers were really cold, sometimes the touch ID would act up. Also, as previously stated, lotions and oils on the fingertips can cause it to act up, as well. If all else really does fail, then she may need to replace the home button assembly or the Phone itself. Have her keep working with it in as many ways as possible, as she may just find the solution without updating or repairing the phone. Unfortunately, equipment does just ware out sometimes.

My iPhone SE first generation is having problems with touch ID. I’ve cleaned the screen and the home button several times. Run through other troubleshooting steps including resetting all of my settings. And rolling new fingerprints.
The new fingerprint will work for a while and then start to fail after a couple of hours or days.
Just tried troubleshooting with an Apple agent but somehow we were not able to send diagnostics. So, my next step is to go to the Genius Bar and have them check it.
Couldn’t find replacing the home button in the pricelist.Replacing the screen is really expensive. I probably won’t bother. I’ll probably just buy a new phone and give this one away. Trade-in value isn’t very much, especially if there is damage to something like the home button.
Tried some tips from this page https://www.makeuseof.com/tag/iphone-home-button-working-fix/amp/

If there does not appear to be any damage to the home button, I will upgrade from iOS 13.7 to iOS 14 doing a factory fresh install.
By the way the agent wasn’t able to share my screen either. probably some setting I didn’t have right.
