C6903 ear speaker problem

[czaknorris]

Hi!
I just recently bought the Xperia Z1 (C6903) and I have a really strange problem. Whenever I make a call or I answer one I have to wait 3-10 seconds before the ear speaker turns on. The other side can hear me perfectly, but I can’t hear them. The problem doesn’t exist when I’m using a headset. After I start hearing the other side the sound quality is perfect and there is no problem until another call. I am running official 5.0.2 ROM version 14.5.A.0.242. I didn't root, didn't unlock bootloader, just did OTA update. Any ideas?

Well... Nothing helped. I tried everything I could without compromising my warranty. I'm going to return my phone and get something else, maybe a HTC.

I might try the Z3 but it's quite pricey considering it's almost the same under the hood as a Z1.

The Z3 it's a lot better than the Z1
