mlieskyx3,
As you can see, there seem to be a lot of people posting here who are recommending that you take your phone apart and fix the problem yourself. They don't seem to want to tell you that, despite their claims, Apple has made it patently clear that once a phone is opened by an unauthorized party (meaning not Apple and not an AASP), you take a very real and very likely risk that you will not be able to get any help from Apple once that has occurred.
Since you won't be taking your device directly to these posters, and since they have no way to know what your skill or knowledge level of doing intricate hardware repairs on a delicate, complex, micro-computer, they have no way to ensure that their advice will be successful. Their agenda is clear - they are not interested in finding the best outcome for you, they are interested in furthering their "right to do-it-yourself" movement.
If you take a look at the article I posted the link to above, you will see that the author has provided a very thorough and detailed explanation of why you don't want someone other than Apple messing with your iPhone 6 or above device - especially when the issue involves the Touch ID.
No one is disputing that people have the right to make a choice. I'm certainly not disputing that there could be circumstances in which having a 3rd party repair your device is the most economical, and most reasonable route to take. I do take exception to the cavalier way in which several posters are saying that they have done this many times and it has always worked out fine. If you read the linked article, you will see why I am dubious about this claim.
Proceed at your own risk here, and make the decision that makes the most sense to you.
Best of luck with your issue,
GB
