No Audio after Repair

It's actually doing the opposite, won't recognise any earphones if plugged in, just displays regular Volume/Ringer. It will play audio through Bluetooth devices if that means anything.

That is very strange. Try unplugging the charging port assembly and then turn the phone on again and do a call test. See if you can hear the dial tone after making a call on the earpiece speaker.

If it works there then I suspect faulty assembly as said above.

Thanks for the help, will give it a shot tomorrow!

So it turns out the earpiece was working anyway, just quiet due to the age of the phone.

Would you recommend swapping out the bottom assembly then? just seems odd that the audio jack and speaker would not work when the charging port and microphone do.

Thanks again for the help.

Yeah sounds like the charging port assembly is defective and needs to be replaced, this is assuming it worked before repair.

Earpiece being quiet that should be easily fixed with cleaning the little black filter at the top with cotton buds / fine bristle brush might take a minute or two of cleaning to get it clear again.

Most of the time it can be cleaned without opening the phone, worst case you'll need to remove earpiece speaker, shine a flashlight through the filter from the front of the screen and clean carefully accordingly until you see some clear dots of light going through.
