Touch ID problem - IPhone 7

Hey guys, does this happen to you guys as well and why does this happen any solution?

I would leave my fone turned off for 2-3 weeks and when I turn it back on it won't recognise my fingerprint. This is the 2nd time this has happen. Occurs when I leave my fone turned off for 2-3 weeks then turn back on to use.

Anyone else get this issue?

 

Yes of course. Sometimes I have to go away on a trip and leave my iPhone 7 at home turned off for about 2-3 weeks. When I come back home and turn it on it won't recognise my finger anymore. This has happened 2 times now, whenever I leave the fone turned off for 2-3 weeks.

 

Well first I have to unlock it with my passcode when first turn on in order for Touch ID to be active. After doing that I will try unlock my fone with Touch ID and it would not recognise my finger.

 

Yes it's still registered in settings. If I re register them again it will work. But I'm just curious why after 3 weeks of no use and back to use again it won't recognise my finger. Does it have to do with my fingers or something like the prints changing or something to make the Touch ID not read it?

 

Hmmm I don't know it usually always happens to me I don't know if it is my fone Touch ID problem. Or could it be my finger print changing over the 2-3 week period as I smoke and sometimes it leaves brown skin on my fingers due to the tar and skin being thick etc.... could that be the case . Really wanna know and solve this issue.

 

Still doesn't sort out my question or anyone have similar experiences? Cannot figure out if it is my fingerprint itself or my fone.
