Taptic Engine Motor weak vibration
I have Changed Back Housing on an iPhone SE2020 which previously was bent. After that I have fitted back everything and I have tested vibrator motor but it is very weak. It makes very tiny sound or vibration but it is not normal.
I have tried an 2 good iPhone 8 Taptic Engine but it is the same problem.
Every other function of the phone works perfect except this.
The board has no damaged components on it.
Any suggestion how to diagnose or move forward? Thanks
Es esta una buena pregunta?
