Repairment policy- iPhone unfixable?
My iPhone's glass was shattered on August.
The glass was replaced at my carrier's labs with an unoriginal screen without my awareness.
The Touch ID Sensor started lately to function on and off until it completely stopped responding.
I Previously managed to update to 9.2.1 and my iPhone worked without the Touch ID Sensor.
I erased the iPhone and downgraded it to 9.2 and the Touch ID started working again. After couple of days it stopped and never worked ever since.
I updated to iOS 9.2.1 and the iPhone is bricked (Unable to downgrade since 9.2 in unavailable).
I was told by a premium reseller that a glass can not be replaced without replacing the Touch ID as well. And Their policy, as well as Apple's is to change the iPhone to a new one.
Apple representative told me they won't check or fix my iPhone , neither will the premium reseller (Even to understand whether I have original parts or not).
I don't understand, If my iPhone's screen shatters then I must buy a new iPhone?
My brother's iPhone's glass was shattered, he replaced it at a third-part lab and his iPhone 6 works with 9.2.1.
I don't understand if the glass must be replaced with Touch ID
I don't understand if the glass's unoriginality itself can cause iPhone to become bricked.
I don't understand if every time my glass shatters I must buy a new iPhone
I don't understand if I can find out some how whether I have an original Touch ID or not (not Apple nor a Premium preseller want to help)
I don't understand if I can rescue my iPhone, if my Touch ID is damaged or just unoriginal parts
Please help 😟
Thanks for the helpers
iPhone 6, iOS 9.2.1, Touch ID
