Hi all,
After a screen replacement (owner said, phone has a genuie battery replaced a few days before), when touch id is active, home button gets crazy hot. I thought, backplace flex damaged and replaced 3 back-plates, still no success. I have a faulty backplate, when I install it, home button works without touch id and no overheating.
What may cause this ?
Thanks in advance

Touch ID or various components that are connected to the touch ID chip on the home button flex are damaged causing a short circuit and heating up. Looks like it’s going to have to have a replacement home button with no touch ID to fix that.
That is usually pry damage on the home button flex.

Thanks for the reply.
As I said, when I install a faulty backplate, home button works without touch id and no overheating. It can be a solution but I want to try to recover the phone before go that solution.

Problem with iPhones and home button replacements are that they are married to the board which can cause the error 53 code after replacement. If a third-party repair shop replaces the home button and you’re running iOS 9, Apple automatically bricks your phone.
Once your iPhone is bricked, there’s no way to unbrick it.
This is all pushed as a security issue but the storage for the apple touch id is with a coprocessor and not on the board, icloud, apple database or anything like that. Great in that sense but horrible that 3rd party repair shops are pretty much locked out of doing certain repairs all because of a greedy/poor implemented security function.
For hot home buttons, it is a known issue in the Apple community on model 6’s. Many simply recommend a hard reset on the device, I doubt this is your solution but I figured Id add some input into the whole discussion regarding touch id / et al.
Thank you Apple for all of your wonderful and innovative designs. /sarcasm/

I mean you´ve replaced the flex cable and it still didn't work.... I really don't know by this point.
