Why is sound/mictophone/vibrator not working?

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.

I forgot to add that headphones don't work either .

Will they work if I change the charging flex ?

Try disconnecting the charging flex and see if u get headphones working, failing that plug in the charging port and disconnect the headphone flex it's the one connected to the volume buttons and see if u get sound out of the bottom :)

First thing I would swap is the charge port. As this controls all the functions you mentioned (minus the vibrate issue)
