Unhappy Problem Z2

I have problem with incoming call sound quality, I can hear them but there is some hiss and scratchy sound that I hear most of the time. I have been to my poor agent in Bahrain many times and they have changed the mother board twice but still the problem exists !. finally they have decided to change the full unit, and surprisingly the same problem occurred on the first call !!!. I was thinking that the quality of Sony Z2 is bad however, but my friend has Z1 and I have used it and the sound is very clear. !. I
I took my Z2 to another agent we have in Bahrain and they have tested the phone and they said that there is problem on the speakers. but they can not repair it because of my warranty is under the first agent !. So I took it back to the first agent and they are not willing to repair my phone. I have complaint this to Sony since 23rd Oct 2014 but still no reply ! all what I receive from Sony is that we will investigate. my request No. is 1-2167511972.
Any one can speed up my complaint ! I think Sony you know very well that there are many phones having this kind of problems and you need to act faster to satisfy your customers !. now almost three months passed and I do not use the this phone and also the value of Z2 has gone down !

I'm unsure when this issue surfaced whether it was there before, but I recall some people saying they couldn't hear well.

It's been for repair for unrelated issues and was returned a week later in this month. The issue has got so bad the person said I wasn't speaking English anymore.

The new firmware it came back with

23.0.1.A.0.167, may have made it worse. Such a disappointment from being the best phone ever to not a usable voice phone without a headset (wired or Bluetooth). The microphone can record and perform better with apps however 3g network calls is very difficult to impossible without a headset mic. How can they get this so wrong.

I discovered that the problem of the microphone depends on how high we set the listening volume. More lower the volume during the call, and the caller more we feel better. Try!
I doubt that suppression noises like it was always active

I have Sony Xperia Z1 and after a recent software update about a week ago (01. 06.2015) other people hear my voice braking up constantly. At the beginning of a call for about 20 seconds is OK and than it gets worse and worse! - to be honest it is complete negligence to release a phone or a software update with a such fault. I keep wandering what is wrong with Sony developers. Just wanted to ask why don't we all start writing complains regarding these issues directly to Sony and see if there is a reaction to our emails. Still. sooner or later these problems must be sorted and of course better if we push for their earlier solutions.

P.S. I have just e-mail the problem described to UK Support:

SONY Respond here:

We would suggest that you try to perform a repair of the software using PC Companion. If the issue is related to a problem with your software this will be repaired and your handset will work as intended. To do this, you will need to install PC Companion from the Sony Xperia website. Please follow the steps below to do this:

1. Go to
2. Select Support
3. Choose your handset from the list provided
4. Move to the bottom of the page and find ‘Connect Your Computer’ and Select PC Companion ‘Read the Details for Windows’
5. Select ‘Download’ once you have checked the requirements

To then perform a repair on your handset’s software, please follow the steps below, making sure that at the start of the process the device is turned off and disconnected from the computer:

1. Open PC Companion
2. Start 'Support Zone'
3. Select Phone Software Updates
4. At this point a pop up will appear on screen asking you to connect your handset while powered on, as the software repair needs the handset to be switched off please ignore these connection instructions and click on the blue link which states "Repair Phone”
5. Some on screen steps will now appear for you to follow. Please also connect the handset when you are prompted to do so.
6. When you are asked to connect the handset (still with the phone powered off) please press and hold the key stated on screen for 30 seconds before connecting the handset and keep it held down as you connect
7. The repair process should now begin.

Please ensure your handset is not connected to your PC when performing the above as you will be instructed to connect your handset once you have followed the above steps. Your handset must also remain powered off at all times.
