I haven't, as I'd probably say I'm in the same boat as you are right now

Occasional and bad stutter but 90% okay...

I'd still like it fixed!!
[Xperia Z5 General] vaderag:
I've noticed the primary issue occurs almost exclusively in service changes; mobile, 4g, WiFi.

Let me explain...

I start BT and leave the house. Partway down the road I lose WiFi... Stuttering for a minute or two.

I get the train and it goes through a tunnel. Stuttering

I head underground, stuttering. Couple of mins later being underground is no issue

It's the change that does it.

All my music is local btw
[Xperia Z5 General] vaderag:
I retract my comment above. Yesterday in the car it was awful. Had to turn the damn Bluetooth off it got so bad. Gonna try disabling throw if it has any kind of positive effect. Still working for you guys?
[Xperia Z5 General] mrbubba999:
Updated with official EE software the other day, went to use the Bluetooth this evening and I've never heard it this bad, could not make out any music, just constant skipping!

Hope they roll out an update soon and EE allow it through
[Xperia Z5 General] fr500:
Ugh, well it seems I'm not alone at least.

I'm very bugged about this issue. The phone is almost $1k with the taxes we have in Ecuador, and a flagship handset shouldn't have this issue.

They offered me a replacement at the local Sony Center but my brother's Z5 does the same and it was bought in Canada so it's unlikely a hw issue.
[Xperia Z5 General] millicent:
I think Sony mobile knows about it but there's no fix yet. You can try to use different speakers or headphones as some work better than others. Or downgrade your fw to lollipop until an official fix.
[Xperia Z5 General] saintdragon7:
Im pretty sure Sony is aware of it, but refuses to admit the problem. I contacted sony many times and all i get was to perform a repair via Xperia companion. did it, reinstall all apps, wasted 3-4 hours, doesnt work.

If the next update doesnt solve this simple problem im leaving sony for good. cant believe i bought their flagship Xperia Z5P so that ill have to use AUX when driving.
[Xperia Z5 General] millicent:
Hehe, I feel your pain. Am using wired headset now cause the cracking noises became too unbearable this morning.
[Xperia Z5 General] saintdragon7:
Lets hope Sony will start rolling out the fix very soon
[Xperia Z5 General] vaderag:
I'm planning to eBay my phone in the next few weeks once I've found what I want to move to - predominantly for this issue.

I also have other problems with this phone, namely inability to format an SD as internal storage and the atrocious power drain when the screen is on. Battery is lucky if I get 6 hours from full... I think this is really poor show from a flagship phone
[Xperia Z5 General] danw_oz:
Google will need to fix it first, since the issue is in the base OS
[Xperia Z5 General] vaderag:
Not according to the rest of this thread and my other mates with Android phones. Sony themselves seem to have indicated it's an issue with their FM radio interference
[Xperia Z5 General] Xaviez:
I've bought an HTC one a9 partly because of this problem with the Z5 and it does not have this issue, so it's not a marshmallow wide problem, it could ofc be base os having a conflict with certain hardware though.
[Xperia Z5 General] bartolo5:
I have a Nexus 6P with the latest FW, and while it's true there are BT skips every very now and then, it's nothing like my Z5 which is not usable.
[Xperia Z5 General] danw_oz:
Mine is usable, either close all apps with the close all button fixes 95% of stutters on mine, for the other 5% a reboot fixes it for about a week.

---------- Post added at 07:28 PM ---------- Previous post was at 07:26 PM ----------

So why didn't they fix it already with the .163 or even latest .185 firmwares. Chances are they could maybe implement a work around by say giving more priority to bluetooth at the kernel level.

Try a google search bluetooth stuttering (or similar) with marshmallow, huge percentage of phones considering how few a even running Marshmallow even to this day. Google even has it one their MM bug list still to fix.
[Xperia Z5 General] bartolo5:
I don't spend $600 on a phone so I have to babysit it, specially when virtually every other phone in the market, their bluetooth works just fine without hackery. Gee, even a $150 Moto G has perfectly normal and functioning bluetooth...
[Xperia Z5 General] millicent:
It appears Sony is working on an update to fix this issue amongst others. A Sony community manager said to expect it in June: http://talk.sonymobile.com/t5/Xperi...r-after-marshmallow-update/m-p/1125949#M18615
[Xperia Z5 General] vaderag:
Hope they sort it out!

I worry that they say sound quality improvements tho - it's not an issue with the quality of the sound, just the continuity of the sound!! I'm sure i'm picking holes and that's entirely what they meant, but we'll see :)
[Xperia Z5 General] bartolo5:
Advertising for Z5 should have read:

Xperia Z5 32 bit DAC/ 192khz with UHD Sound!!!*

*audio stops for 1 second every 5 for processing
[Xperia Z5 General] vinogradov88:
I'm not 100% sure but I think I may have fixed the issue by installing the Xperia Beta APK from APKmirror and updating to the last patch. The FM radio app now doesn't have any options at all, I also revoked any data usage from it just incase. Worth a try if you're still having this issue.
[Xperia Z5 General] vaderag:
The only file I can find there says for Z2&Z3- is that the right one?
[Xperia Z5 General] vinogradov88:
apkmirror.com/apk/sony-mobile-communications/xperia-beta-program/xperia-beta-program-1-1-2-release/xperia-beta-program-1-1-3-android-apk-download/

Thats the one I installed. I don't think it forces any phone.

Although the email I got said it's "closed" my phone had a system update when I went into the "about phone" settings.

I'm on t-mobile , not sure if an update came out over the past few days because I checked before the weekend and there was zero system updates.
[Xperia Z5 General] bartolo5:
32.2.A.0.224 released today, seems to greatly help with the bluetooth stuttering for the moment. Let's see if it holds up.
[Xperia Z5 General] vaderag:
Not seeing that update... is that on the beta? If not, how can I force?
[Xperia Z5 General] diemadedrei:
Just flash through flashtool.
[Xperia Z5 General] millicent:
You need to download the new fw thru XperiFirm, then flash via flashtool. Or wait for your ota.
[Xperia Z5 General] vaderag:
Thanks. I'll wait for ota I think, shouldnt be too long
[Xperia Z5 General] millicent:
Me too am waiting for Nordic customized but less patiently by the minute since I restarted already my phone today and the stuttering is getting worse again..
[Xperia Z5 General] bartolo5:
So I've had 32.2.A.0.224 for about 24 hours and the stuttering is still there but it's more manageable. It started happening again after 24 hours... This is probably more livable.
[Xperia Z5 General] chero90:
I'm a few hours on 32.2.A.0.224 and no Bluetooth problems. But after the update the Z5 rebooeted. I don't really believe, that it is fixed...
[Xperia Z5 General] vinogradov88:
I just upgraded as well and seeing an improvement. My earlier fix lasted a few days and requires resets (it was on and off). This seems much better.
[Xperia Z5 General] saintdragon7:
received my OTA this morning, i hope this will fix the bluetooth issue, including the battery life. :D
[Xperia Z5 General] langeveld024:
Anyone who uses bluetooth Internet tethering?

I'm having continuously disconnect and reconnecting on my tomtom navigation since this update.

Anyone willing to try to reproduce this?
[Xperia Z5 General] jackq:
For me nothing changed after update, still BT reconnect all the time. Crappy ****.
[Xperia Z5 General] saintdragon7:
the update doesnt fix the bluetooth problem....its better but no way good enough...still skipping every min
[Xperia Z5 General] vaderag:
Haven't had my update yet, but disappointed to hear that it's not fixing this...

Let's make sure we keep on at Sony. I may sell my phone before they actually fix it, but nevertheless, let's keep on at them!
[Xperia Z5 General] herasymcuk:
The bluethoot iussue is not fixed!!!!
[Xperia Z5 General] ricodredd:
Just a comment here but I've never had much of an issue with Bluetooth on this phone as regards "skipping". However, I do notice it sometimes when my phone's CPU utilisation spikes like during app updates or coming off airplane mode and hitting the network for updates. Launching big apps can cause momentary stuttering too - sounds kind of like static.

Now, my phone really doesn't have much installed on it but I've seen screenshots of people on here and elsewhere having 100-200 apps installed! Maybe there's just too much load on the phone's subsystem to maintain a coherent Bluetooth connection and that's the root cause and opposed to a faulty Bluetooth radio or whatever.

I guess booting in Safe Mode and re-testing (if you haven't already tried) is something to consider? Maybe monitoring CPU utilisation during skips might direct you to some app you have interfering?

Not really a solution I know but maybe a sanity saver? :)
[Xperia Z5 General] RyTekk:
On the first and second MM update, I got stuttering while playing audio via bluetooth, never had a disconnection while playing or idle (for 2 hours). On third update, the stutturing has gone, I played music for 1 hours and just got a very little stutter. And did you guys do a fresh install? I know it's too complicated but just report bugs when do a fresh install.
[Xperia Z5 General] saintdragon7:
Thanks for the comment, however i only have 82 apps installed, most of the memories are used for Android OS. I am a sony fan boy, most of my gadgets are sony. The bluetooth issue has been around for months, so ya i constantly check my phone's utilization, just because you dont have a problem with your phone doesnt mean other wont have. We all bought its flagship phone, so ya we expect it to play music via bluetooth without any problem just like other cheap android phone. My last 3 phones are sony, Sony makes damn good phone, but they messed up on this one. if its bad why cant i raise my concern? I really dont understand your logic here so yeah sanity saver is not a solution or helping anyone here.
[Xperia Z5 General] ricodredd:
Likewise, just because this didn't help you doesn't mean it didn't help others....
[Xperia Z5 General] vaderag:
New update came through last week and first opportunity to test bt this morning. Absolutely, 100% still as rubbish as it was before. Tried flight mode, still the same. So this is not being interfered with by other radios, it's just crap. Time to sell up maybe?
[Xperia Z5 General] millicent:
I gotta test some more, but from what I can hear it's at least much better. Where previously it'd skip or stutter now there's a small pause. I can probably live with that if it doesn't get worse.
[Xperia Z5 General] vaderag:
I wish I was getting that... do you still have throw disabled per above? Never did that, but maybe that's the ticket...
[Xperia Z5 General] odl:
it will get worse.. just give it some time.. ;) few days without reboot and you'll see.
[Xperia Z5 General] millicent:
I am almost stock customized Nordic 224, only disabled/removed a few apps, but not throw. I am refraining from install anything non stock and testing in google music.
[Xperia Z5 General] millicent:
That'd be a shame if it happens again..
[Xperia Z5 General] ricodredd:
I haven't experienced any BT problems really - just a rare stutter when the phone is under load doing something else. I've just twigged that your headphones are aptX ones and mine are not (Sony SBH60). Throw is enabled on my Z5 too. I wonder if aptX is a common cause?

E6653 Customized DE .224
[Xperia Z5 General] millicent:
I spoke too soon. It's definitely not fixed on 224.

It worked fine yesterday after clean 224 install on my sennheiser aptx and Sony soundbar. It also worked fine this morning for a while on my telme aptx headphones. Then, at first I got these very rare, small pauses. I said, well if that's as worse as it gets it could be bearable. As I continued to listen, these small pauses became longer and more often. Now, my bt music listening thru google music play is a constant noise experience interrupted by actual music.

Cannot believe I waited so much for a fix and then we got this. Guess my mistake for choosing Sony when I was quite happy with previous samsung and htc phones.
[Xperia Z5 General] vaderag:
It's so ironic. Just moved my wife from Windows Phone to Android - got her an £85 Ulefone... does literally everything my Sony does for a fifth of the price, and guess what... the Bluetooth works
[Xperia Z5 General] millicent:
I just left my comments with regards to this issue at http://talk.sonymobile.com/t5/Xperi...after-marshmallow-update/m-p/1103796#U1103796. Suggest you do the same. Who knows, Sony might actually fix it sometime..
[Xperia Z5 General] bartolo5:
Milicent, I admire your resilience with this issue.

There was someone in those forums from Sony Sweden saying that a fix to the BT skipping is actually on the way, no ETA.... I'm not sure if this a cultural issue with the japanese or what, but there's no way other companies would let an issue like this linger for months like Sony is doing. Apple would have fixed this in days, and bluetooth music playback is such a common use case that's hard to grasp why Sony is not picking up their feet.
[Xperia Z5 General] vaderag:
So true... makes no sense and clearly is a widespread issue...
[Xperia Z5 General] millicent:
I am definitely disappointed in how Sony addressed this issue. On the other hand, as a dev myself, after so many years I should know there's no bugfree software.

That out of the way, I actually do suspect this issue might be less widespread as it seems. How can I explain otherwise only 30 pages of posts on sonymobile's relevant thread. I mean, there are many more people, I assume, that bought z5 series and also listen via bt? So, it might be that there's a very specific hardware defect or even a software customization (remember how at the very beginning of this thread I was asking you to post your complete configuration) and Sony engineers are having a hard time reproducing and consequently fixing it. How else can you explain them, say, being able to reproduce the problem, fix it, then not testing it for a few days to make sure it's alright?

In conclusion, my guess is this is a quite rare issue that, lacking the capability to reproduce, the devs are fixing it 'blindly' in a kinda reverse engineering mode if you will, based upon the various stacktraces we've given them.

I guess sony will still finally and perhaps silently fix it someday, even with the 'rare' occurrences it's becoming more and more embarrassing, so there's that and, yeah, still hoping to fix my phone;)
[Xperia Z5 General] FYLin21:
I think it is a lot better in 6.0.1 with my JBL Charge 2, but it still skips very occasionally. It's really bad if you have the gallery app and are scrolling slowly through the photos.
[Xperia Z5 General] vaderag:
Thing is, I don't think most people post on the Sony forums... I mean, I only did coz you asked ;)

Also, in can understand it doing it while scrolling photos etc (I'd still rather it didn't, but I could live with it), but when it does it still with all apps closed and flight mode on, then that's an issue.
[Xperia Z5 General] TobbeSwe:
If we want Sony to change things up we can´t comment on the official forum, they need reports directly to them through their chat or email or facebook.. And their can´t be only one or two who contact them, it has to be more then that before they even do anything about it..
[Xperia Z5 General] vaderag:
Agreed. Just posted on each FB wall and twitter account...

Don't suppose much will come of it, but gotta try!

---------- Post added at 12:16 PM ---------- Previous post was at 11:26 AM ----------

Got responses on both Twitter and Facebook - it's been fixed in latest update. I have tried to correct them, but if that's the party line we're screwed...
[Xperia Z5 General] millicent:
I have tried to reply to Sony's twitter account in the past on this very matter. they either ignored or removed my question, I guess there's some moderation work in there too.

I have created this reddit thread if you care to join:

I just got an OS upgraded pushed to my Xperia Z5 today and the stuttering issue went away. In the highlights of the fixes was BT audio.

Model: E6652

Android 6.0.1

Kernel: 3.10..84-perf-g4a67e86

Build Number: 32.2.A.0.224
[Xperia Z5 General] vaderag:
Yeah, that's what we're all on. It's not fixed...
[Xperia Z5 General] 56kz2slow:
Yeah, it was a false positive. Yesterday no issues during 4 hours of listening to music using Google Play Music. This morning, it was in the 3rd song before it started (better than first 3 seconds of first song I guess). It's less frequent, but still present. Happy about the improvement, would be much happier if the issue was gone.
[Xperia Z5 General] saintdragon7:
Just received an update, hopefully this update will finally fix the problem. Its been so long ready!

PS. any Z5P user here experience faster battery drain since Android MM ?
[Xperia Z5 General] vaderag:
Dont get your hopes up. While it mentions a fix, it's a negative
[Xperia Z5 General] vaderag:
I have a question... has anyone managed to find headphones that DO work with this phone? I don't mind forking out some money for them, but at the moment I just want some bluetooth headphones that work!!
[Xperia Z5 General] ricodredd:
SBH60 headphones work fine for me. Only paid £20 for them so not high-end gear but they're pretty good.

I've not been having BT problems like many in this thread though so the credit probably shouldn't go to the headphones. BT audio works fine in my car and with a Juicebar speaker I have too.
[Xperia Z5 General] vaderag:
Ah that's a point - buying new headphones wouldnt solve my car :(

Can you post some details about your setup? Which firmware etc you're on?? Rooted?
[Xperia Z5 General] ricodredd:
Stock setup, Customization: 1298-3675 (Customized DE) running 32.2.A.0.253-R3C which came out yesterday.

This new firmware contains "improved BT handling" but I wasn't having issues before either:

http://xdaforums.com/showpost.php?p=67710320&postcount=5
[Xperia Z5 General] odl:
you're saying you never had short audio skipping during listening via BT? even after having phone turned ON (without any reboot) and not cleaning RAM for few days?
[Xperia Z5 General] ricodredd:
Well it wasn't perfect, just not problematic either. It worked fine 99% of the time and I have heard the occasional stutter (phone under load, for example) for sure but, overall, no complaints. Weekly reboots seem to be the order of the day for my Z5 anyway.

Put it this way, I installed the new 32.2.A.0.253 firmware about 20 hours ago, listened to 2-3 hours of music since and haven't heard a single glitch.
[Xperia Z5 General] vaderag:
So 253 is a new version... think most are on 224

Fingers crossed the fix it this time!
[Xperia Z5 General] saintdragon7:
Mine was updated to 253 yesterday, to my surprise it's been over 24 hours now, not a single stutter/skip over BT yet. I'm giving it a couple of days more
[Xperia Z5 General] bartolo5:
Please report back!
[Xperia Z5 General] RyTekk:
I think bluetooth stuttering was fixed in 224 firmware because I got that problem on the first MM release, but after I updated to 224, it's gone, I listen to music every by my SRS-X3 about 3-5 hours, so I can tell that the problem is gone 99% (1% is left for unexpect moment :laugh: )
[Xperia Z5 General] tomo100brt:
After about 24 hours I am not having any sound statter over bluetooth on 32.2.A.0.253 firmware even when I am using other internet apps when listening music over bluetooth.
[Xperia Z5 General] odl:
Can you try using more resource demanding apps during playback? e.g. some maps navigation? Also please try to fill RAM with something.. chrome browser with several tabs open, playing some game before listening to the music etc... and don't swipe apps out from recent apps for testing ;)
[Xperia Z5 General] saintdragon7:
48 Hours, still good 0% stutter/skip , and I have tested with many apps opened (RAM consuming apps). Hope the nightmare is finally over :D
[Xperia Z5 General] vaderag:
Fingers crossed - bring on 253
[Xperia Z5 General] odl:
unfortunately can't confirm on my 6633. tested today with .253 and it behaves just like on previous versions. do you still have it working 100% fine? if yes, did you wipe data after update, or kept all settings? I don't want to bother with reinstalling whole phone if that's not the case... ;)
[Xperia Z5 General] tomo100brt:
This is the last report for XPERIA Z5 because now I have XPERIA X Performance. Even today I don't have statter with Sony Stereo Bluetooth® Headset SBH80. This morning I played games and no statter. I did not wipe data, only update through XPERIA Companion. My thinking is that they fixed problem for some accessories (maybe Sony accessories) because my friend uses non Sony bluetooth headset and has statter.
[Xperia Z5 General] tosmaniac:
I confirm Bluetooth issue gone with 253, used plantronics black beat.
[Xperia Z5 General] millicent:
It appears Sony finally fixed this longstanding issue in .253. At least couldn't reproduce it so far on Nordic combined, ota, no-wipe, 3 days uptime. Hopefully it stays this way.
[Xperia Z5 General] vaderag:
Hallelujah! Now just to wait for my update
[Xperia Z5 General] odl:
I'd like to add a comment to my previous statement that it's not fixed for me on .253 - one of the rootcauses is actually fixed - I have my device for 5 days now without reboot and "skips" amount didn't increase over that time (with previous version it was unbearable on that stage already), so I'm getting just short ones once per few songs. Moreover I noticed it happens only when I move (driving car) so it may be related to switching between some cell towers or some signal interferences, but not memory leak anymore.
[Xperia Z5 General] gusbeto37:
Hi,

I flashed 253 some days ago and the bluetooth music issue is gone.

But I still have the bluetooth call issue where the call will still be going on but suddenly the bluetooth doesn't transmit it to the cars audio.

Doesn't look like it's been released yet in any form. Xperia Companion would always have it first so if it shows up on the site linked below you can plug it into your PC and update from there. OTAs generally lag behind, sometimes by quite a bit.

I'm on Customized DE so you could just cross-flash to that regions' firmware. It always seems to be one of the first to receive new updates too.
