touch id doesn't work after battery replacement
replaced the battery. no problems. afterwards, though, as soon as the phone starts, says it can't enable touch ID. when i try to enable it in settings, i get an immediate failure. double tap also doesn't work to bring the screen down. otherwise phone working fine.
Is this a good question?

force touch works. took it to a ubreakifix store and tried replacing entire screen - didn't work. visually inspected the cables and motherboard - no damage.

Paul, probably something on the board is damaged because of corrosion or there could be a short circuit. Disassemble device, clean board of any corrosion, with magnifying glass also check all solder joints for being,poor, cracked, burnt.
