Vibrator not working on iPhone 4S
Hello everyone !
After changing the screen of an iPhone 4S that was dropped, I check all the different part. And I notice there is one thing which doesn't work : the vibrator.
I did not know if it's my fault, so I disassemble again the iPhone and I check if the motor contact (two little springs) are aligned with the contact motherboard, it seems good, I cleaned them with alcohol to be sure.
I reassemble the iPhone, but the vibrator still doesn't work... :/
All of the other part are ok :
Volume buttons : OK
Mute toogle : OK, when I switch, the iPhone display me a popup
Headphone jack : OK, when I plug headphones, the sound is ok.
How to be sure it is the vibrator motor that is defective ?
Is there a simple way to "test" this part, for example branching an alimentation on the two little springs ?
I just want to be sure it's not a faulty cable...
Is this a good question?
