I replaced my iphone 4s screen by my self.
When I was finished and checked the phone I found out that there was no sound coming out of it at all. No sound from either speaker.
(both cameras worked , bluetooth and wifi worked and celural antena worked)
I tested it by making and receiving a call and I found out that neither my microphone nor my vibrator was working.
I tried rebooting and hard reseting it but it didn’t work. That let me to believe it is a hardware problem.
I reopened the phone and made sure all the connectors where connected properly , and they were. (still all those things I mentioned didn’t work)
I probably damaged something during the repair.
What can I do ? Do I need to replace anything ?
By the way I filmed everything with another phone (quality is bad) , so any expert can briefly watch it and maybe tell me where I did wrong.
