Haptic Feedback not working after installing a brand new Taptic Engine
So a customer gave me an iPhone 7 without Haptic Feedback.
I bought and installed a new Taptic Engine but it still doesnt work. After that i swapped the Lightning Connector for a new one, because thats where the Taptic Engine plugs into. Still no Haptic Feedback.
The phone is NOT water damaged and never went into repair before. What could be the problem?
