[Q] 4.3 Bluetooth Audio Quality - Xperia Z1 Q&A, Help & Troubleshooting

Is anyone else's music through bluetooth terrible with the 4.3 update? Any ideas on a fix? I've tried various ftfs and full restores to no avail ;(

What do you mean terrible? I'm using MW1 with 4.3 and everything is fine, with less power consumption.

Mainly constant crackles/distortion on highs (cymbals, etc.), running through both a DS220 and a Sony BT stereo. I've experienced it on a lot of other phones/devices over the years but never on something made by Sony I've looked through some threads on generic issues with 4.3 BT audio but I just wanted to see if others were having the same issue with this specific firmware first. Do you know which update you're on?

I'm using a Sony SHB20 headset and i'm on 4.3 update 14.2.A.0.290 and I have the same problem. The sound is terrible... It's like a crackling sound... Can't say if it's because of this update, becuase I didn't try my bluetooth headset until this update, but the problem is definetly there.

Yeah, mine definitely sounded great before the 4.3 update - with my limited knowledge I've tried replacing the a2dp and bluetooth .so files from other .290 firmware and even the 4.4 z ultra firmware with no luck. Not even sure if it should work anyhow.
Did you unlock your bootloader or root?
There is another thread for this on Sony's site that hasn't been active since last week also but may be good to keep an eye on (can't post links since I'm a n00b)

Yes here I have same Problem before the 4.3 update the sound was fine. Now its Bad as hell hopefully somebody can fix it because I listen a Lot of music over Bluetooth headset. Im on a generic Europe 4.3 Firmware rooted and unlocked Bootloader. Sry for my bad english coming from Germany

Possible temp fix?
There's an app on the play store called "xperia z1 bluetooth media fix" that you might try. I haven't listened enough to tell if it works very well but from the test I did earlier it seems to sound a little better, but to me it's still not quite as good as I remember on 4.2.2.
Let me know how it works for you.

I've tried this app too but I Don't here any Differenz But I search on Google and found out that the Google nexus Devices had the same Problem with 4.3 Firmwares... There was a fix for it but it wont Work for us. Bluetooth fc's After I try to replace the 2 files(audio.a2dp.default and Bluetooth.default) in system/lib/hw. So maybe a dev could take a look @ these 2 files and edit them for better quality because I cant open them and I dont want to break my Bluetooth

Bluetooth A2DP quality on 14.2.A.0.290
Acknowledged. I have exactly the same problem. I use two headsets : MW600 and Smart Wireless Headset Pro and both have this problem. I can say that the problem was due after upgrading to firmware 14.2.A.0.290. On firmware 14.1.G.2.257 everything works perfectly. Yesterday I installed several times 14.2.A.0.290 and 14.1.G.2.257 and accurately shows that 14.1.G.2.257 everything is OK, but on 14.2.A.0.290 like 64kbps .
As mentioned above, a topic about the Nexus 7, a similar problem. There it is treated by replacing 2x files. It would be great if someone knowledgeable would look at it all. Because wait for a fix from Sony can be very long ...
I found the topic at Sony, who cares - and vote for the issue. Maybe then Sony will release an update. Bluetooth A2DP quality on 14.2.A.0.290

Link to the files you're talking about?

so here the file from my Xperia Z1 C6903 14.2.A.0.290 Central Europe:[URL="https://www.dropbox.com/s/24zwvp1tkjeeafu/Bluethoot%20files%20Xperia%20Z1%20290%20firmware.rar"[/URL]
For now i Switched to SlimKat 4.4.2 Rom because of this issue with Bluetooth.But if you can fix the Problem this would be great !!!

No one can help? :crying:

Hi, I am facing the same problem.
I have a SBH 50 headphne, and the audio quality is worse than with my Xperia S. Plus I get constant reconnection, it get disconnected and it connects a minute after. I think this may be related to the throw feature.

Weird Problem, Audio related

I got these ibeats earphones, worked fine on my sony Z until today.
I thought it might be the earphones but these work fine when connected to other devices(different phones,laptop etc)
So I thought it might be the Sony Z
The free earphones that come with the phone work fine, infact I have tried multiple different brands of earphones just to make sure and they work fine
But
As soon as I connect my Sony Z up with my ibeats no music comes out of them, infact it comes out the phone speaker.
Never rooted or flashed my phone, all standard
Only thing recently changed is that my Z got the 4.2.2 update last night, they been working fine since April so i don't understand. Since I got the update I listened to some music on my way to work, no problems, on my way back home that's when the the fatal weirdo problem occurred. I would appreciate any help or suggestions to amend this?

u r saying this happens only with ibeats earphones? thats weird..
this appears to be a software related issue.. do u use any apps lyk smartkey or smart connect? if yes then check the apps' settings.
additionally, r u using walkman app or any other app for listening music? try to check in the player settings too.
hope this helps...
hit thanks if u feel i have helped u in any way....

I don't those apps, What are they for? tried xperia diagnostics and got the earphone to work but only one side was playing so i suspect, its fault or cable issue, which is the reason why this happened, taken back the beats for cash back, using the sony ones for the time being. I only use walkman app, player settings don't have much except to change the equalizer. Asked one the gurus at the store I got and he advised that alot of people with sony phones sometimes have this happen with perfectly works ear/ headphones. very usual.
Sometimes new updates just makes it incompatible with some headphones. Like beats headphones from dr dre. It doesn't seem to work for some Xperias or all Xperias.
There was a thread somewhere, forgot where but there's another way around it if you search it up. Try googling it or sth.
otherwise downgrade it to use those headphones or stick with Sony headphones.
You can try repairing it with pcc or sus, or flash another ftf file.

If you are using SmartKey, disable it. Connect your earphones, play music, disconnect & reconnect the earphones.
This worked for a few people, hope it works for you too.
Interesting, some Apple earpods are also causing trouble since updating with the 4.2.2, i have a Bose AE2 but haven't tested yet (i'm at work) i have a bad feeling about this and i hope my Bose still works. Many people seems having troubles with their earpods/headphone.

What does smartkey do? got my new earphones coming through, I hope with the new set I wont experience any problems. Sony work well but volume sucks on them, is there an easy way to increase the volume on this device? Safety crap annoys me, back in the day walkmans were crazy loud. What ever happened to giving the consumer a choice.

Some great tutorials in the development section for when you're ready. If you're investing money in decent earphones then the improved sound mods will certainly benefit you.
Xperia Z
Its because your beats uses a inbuilt microphone... my Apple earpods also has inbuilt microphones and the Xperia Onyl recognizes Headphones without mics
got the same problem but i must click like 5 times on the headset (play button/answer button for calls) to make it work so the music goes trough the earbuds
try some headphones without micrphones built-in and see what happens then!

Sadly do not own the earphones any more but I do have a new set that works fine, remote and mic are questionable as this was made for apple products but I do not mind , What earphones do you own if you dont mind me asking?
Are those the ibeats from htc? That could the issue because mine don't work either. Htc told me is an issue with the headphones since they are specially made for htc phones.

SmartKey lets you configure the button on the earphones.
You can set it to perform a different action when you press the button multiple times.
For example, you can set it up such that if you press the button twice when music is playing, it skips to the next track.
You can't change the actions, but it is a bit useful.
As for the volume, take a look here & here.

Hi,

I came from HTC and I was sure that Sony have to be better in terms of sound and camera but I am a little bit disappoint. Overall pls help me with volume issues.

You can change settings for Headset, Phone Speaker and Bluetooth Device.
I'm not sure about the volume in a call. Maybe it won't get affected. Can't test it right now.
But the described things, like the speaker will get affected and there are some possibilities to
gain volume. Maybe there are some easier ways.
But one thing is for sure, your overall sound quality will rise if you use this driver.

dont blame Sony. Blame EU. Flash any ROM for a non-eu country.

Many years ago Sony was one of the first companies to comply with new EU limits on the output of headphone devices, designed to protect the user from over loud sounds. I believe it originated in France. With some makes of music player you could get around this by loading another region's firmware.
It's typical EU "nanny state" legislation. What it unfortunately doesn't take into account is a) not all haedphones have the same sensitivity and b) not all listening environments are equally quiet.
I can't say whether the SPs rather poor maximum headphone output stems from this or has another cause. What does annoy me, and the Sony is not alone in being like it, is how I only seem to have 3 or 4 useable levels all bunched at the top of the control, with large steps between them making fine control impossible, whilst the rest of the volume control seems to do sweet F.A....

I tried to repair firmware with PC companion and nothing changed...I have not seen any improvements. After that I put CWM on the phone and burn a non_EU Stock Rom ( I though from Russia)....other bad news...mu mobile data stop working even I put a new APN from Vodafone Romania. Also low volume in call on speaker was the same. The last I revert to a Vodafone stock ROM from Spain and I thing it's working a little bit better but not satisfactory.
I can't listen the other end in a noisy environment.

I'm sorry I'm just an ordinary user with no technical knowledge. I saw on Sony's support forum that they suggest repairing to resolve many issues so I thought I'd give it a try.
All I did was link up my phone and computer, run repair and follow on-screen instructions entirely. Once finished my phone's internal speaker becomes much louder.

android 4.3 f*cked up my bluetooth audio

hi xda,
i finally got the official .569 update (ota) from sony and it just messed up my bluetooth audio quality. theres some kind of scratching as if the headphones were broken but they worked perfectly with the prior firmare and still do with my ipad. i'm using sony mdr-rbt10 headphones. i, unfortunately, don't have a 2nd bluetooth device to check out if it's only that combination.
anybody facing the same problem?
Sent from my C6603 using xda app-developers app
Hi I don't have the exact same headphones, but I have an Sony SBH52, and a bluetooth car system, which sound pretty much the same after the. 569 update..and I use really supersized senheiser cans so I would definitely notice.
I updated through pc companion.
Though I have seen this problem reported on the leaked. 569 firmware page, you might wanna check that

You can flash a different firmware mate it's not official but it does exactly what SUS does so you don't even need to root your phone. Just install flashtool, download the firmware you want to use and flash it with flashtool
This thing scare the **** out me, i have been reluctant about this 4.3 update, but somehow updated my phone yesterday, and the worst thing is that I just ordered my pair of bluetooth headphone and will receive it anytime soon.Hope this update will not mess the **** out of my bluetooth.

[BUG] Xperia V 4.3 Official Camera

I'm on stock 4.3 fw (SEUS Update). My camera is flickering (green lines) when on low light condition (indoor).
Anyone else is facing this bug? It's incredible.
Did you drop your Xperia V, if yes then that is due to the lens being damaged and some wires broke loose causing the "green lines" you are saying
I suggest you bring phone to Sony and expect to pay since warranty does not cover self-made damages on the phone
mine same problem in 4.1.2 is not there in 4.3 line are there

In 4.1.2 I've got no problem at all. Only with 4.3 camera flickers and record green lines over images.
It's a software problem, not hw.

I can confirm. On a brand new Xperia V (NEVER ROOT/Unlock BL, virgin!) disabling NFC and Image Stabilizer solve the green lines problem.
I can't test at the moment on a rooted Xperia V. Anyone can test and confirm it works also on rooted/unlocked BL device?
^works with unlocked BL as well

It's really strange. It's known to be an issue related to the nfc chip...try (just for test) to disable wifi and bt (and radio) also and let us know.

the xperia v has two microphones on the back and the mic beside the camera records the focus sound really loud i think...

Official 4.4.2 not so great?

Hi, I got this update this week, but it seems to make the UI much uglier and harder to use. Also it feels a bit buggy, the Walkman was randomly playing and pausing on headphones or speaker.
Is it just me?
I'm on UK Generik .290 and still waiting for KK update.... Anybody have the update already?
Sent from my C6903 using XDA Premium 4 mobile app
We know that the KK 4.4 is not so great, users facing many bugs. I didn't update to 4.4 just because of bad reviews.
Make sure you hard reset and wipe the data clean. Usually a upgrade of a software version is recommended to do that.
I haven't had the music player malfunction.
Sent from my C6903 using xda app-developers app
Well the idea of new statusbar kinda sucks because previous was much more comfortable, additionally I experience major camera lag for example when switching front camera to back and vice versa, also phone lags after taking picture and while switching to video. I also experience Force Closes. Touch became less sensitive but as for camera quality I must say that 8MP mode now take great pics even in low light +1.
Excuse my words but after using cyanogenmod and then this... 681 feels like **** more like a broken firmware i flashed cm11 again it is the real KK

That's your Opinion.
Oh, I see. So everyone is having some sort of issue with this update... I hope they fix it, although I fear this is what we'll be stuck with for a long time, unless you go custom.
I've been having problems with the ringtone/notification volumes. This morning the volume was so low, I could barely hear it. Also, there is an irritating 'click' just when there is a notification.
Appears that the official Sony forum is flooded with complaints; it seems that sometimes it rings through the earpiece! I sure hope I'm not stuck with this for a long time. I wish I hadn't upgraded.
Is there any way to revert to the previous update? Or at last change the top toolbar menu back or at least change it? I don't know the term for it...
This upgrade has been the worst for Xperia Z1.*. Problems with sound notifications, overheating of the battery, rapid battery consumption, etc, etc, etc ...
I hope that Sony will soon solve these problems.
Greetings,
Before i flash back the 4.3 which at my opinion is the BEST firmware for Z1 right now , i played with official KK one week and i noticed that the battery life wasnt so great anymore , i had some random overheating problems , the new notification UI its terrible , i had the problem with the sound coming from the ear speaker than the regular speaker , the overall feeling was buggy less smooth .
So yeah i revert back to 4.3 and i am totally happy , loving again my phone , feeling comfortable and reliable .
Cheers
Vatis
I flashed my UK handset originally Vodafone but bought 2nd hand and network unlocked. I used Flashtool to flash CE 1 of KK (681) not had a problem with overheating or any other bugs mentioned at all. I did flashed with full wipe.
The overheating is just happening when i am gaming, but the sound issue is really bad.....cmon!!

toggle for touchscreen
hi, i upgraded my z1 into kitkat and its running very good without any problem (after the update). however today i was in the swimming pool and i was searching for a toggle that can stop the z1 screen from touch underwater, i can remember i saw something like that when i upgraded into kitkat but i cant remember where the option is. badly need to know as the screen responses in a weird way while its wet. pls help me out
