Earpiece sound fault

Hello

I am hoping that someone wise and experienced could assist with this problem that I think is off my own making.

Phone: LG G3
Rooted: No
Android: 5.0

Today I replaced a broken screen and digitizer and the earpiece now appears to be broken. The screen is working fine and has full functionality prior to the break.

The sound however was not working at all - calls or video playback. After opening up the phone again and re-setting the earpiece video playback was working although calls were still faulty. I then checked to see if it was working with speakerphone and it was. Tried resetting again thinking maybe one of the two prongs still was not connected - no improvement.

As it took me 3 weeks to get round to repairing it there were 40 apps to update so not sure if something in this has conflicted and stopped it working but that feels like clutching at straws rather than the likely answer that I have broken it.

Anyone know a possible fix please?

Thanks

Xperia Z3 earpiece speaker issue

Hi,

As the thread title says, my Z3's top (earpiece) speaker has a buzzing/crackling (similar to sound through a fm radio) sound when any sound is played through it. It also sounds a little quieter than the bottom one.

Anyone faced a similar issue? My phone is under warranty - will it be able to be fixed or is it a software issue?
