I ask a technician to replace my battery because it drains too fast. Now before the battery was replaced the Touch ID is working perfectly then when the battery was replaced the Home Button is working but the Touch ID does not. Only the battery was replaced. When I try to register a fingerprint again it doesnt scan my fingerprint as if it’s turned off or something I uploaded the image below
