Samsung Galaxy S3 T999 poor vibration after front assembly replacement
Hello I am a repair shop up in rhode island and ive encountered something ive never encountered before, although the s3 front panel is pretty routine im not sure what happened. the vibration is very poor compared to what it used to be. i gave the phone back to the customer thinking it wouldnt be that big of a deal but apparently it was so i ordered a new vibrate motor and put in a new one and it still was very poor, i told the customer i couldnt fix it but now im thinking.. i was looking at another s3 motherboard and was looking on the bottom side and there are 2 metal contacts for the vibrate, is it possible that those 2 metal contacts arent making a good connection and i need to pry them out a little bit for them to make a better connection on the vibrate motor connections? any input on this matter would be appreciated, i dont have the phone anymore but the customer is extremely upset, im not sure if ill ever get the chance to open the phone up and try but would like to know if i encounter this again in the future. thanks for your help. -pearlcellular
I've never worked on a Galaxy S3, but one thing sticks out when looking at the motors is that it looks like they're held on with an adhesive. If the vibrator motor isn't securely attached to the phone body, it won't transmit it much of it's vibration to the phone itself and may feel weak compared to what it should be. You could try to re-apply the adhesive to body of the motor and then re-install it. This may make the phone vibrate better. As for bending the contacts, you can try that to but be careful as to not break them.
