Can we diagnose somehow that it is hardware issue? I have used following codes in Diagnosis:

*#232331# - BT RF Test Mode

*#232332# - BT Audio

*#232333# - BT Search Test

*#232337# - Bluetooth MAC Address

First one tells me that RF testmode is on, second gives me nothing... Third displays Search Failed!!! message and fourth just same code...
[Windows Phone 7 Q&A, Help & Troubleshooting] rustemka71:
On my omnia

*#232331# - RF Test Mode ON!

*#232332# - Nothing

*#232333# - Search Fail!!!

*#232337# - 0x78471D364188

I've tried the codes and I have the same results as you have, sigh.

My bluetooth dont work with wifi.

And without wifi sound is choppy.
[Windows Phone 7 Q&A, Help & Troubleshooting] japmeet:
wifi or no wifi, my bluetooth never worked :(
[Windows Phone 7 Q&A, Help & Troubleshooting] svarog84:
We all have similar results... Can anybody confirm is it hardware or software issue?
[Windows Phone 7 Q&A, Help & Troubleshooting] rednex2:
joining the club of dissappointed Bluetooth-Users. Same problem here, same results in diagnosis-mode. Absolutely no connectivity. Omnia7 searches for other BT-devices but cannot find anything and cannot be found by any other device. Just contactet the samsung-support (Germany) yesterday - waiting for an answer.

Update1:

Answer: We don't know about a general Bluetooth issue with Omnia7. Try to buy a product from our compatibility list.

Update2:

I bought a Samsung HS3000 BT-Headphone, for the samsung-customer service guaranteed compatibilty, but nothing changed. Bluetooth ist still "searching".

Trying to get a replacement.

Update3:

something happend a week ago. Since than, the "alphabetic character-tiles" on the screen with the list of all the installed apps appear like "border in theme-colour, background in beackgroundcolour, character in theme-colour". . .(seems to be an update or something) and:

even my bluetooth started working again (only if wifi off, ... of course).

It now finds my MW600 Stereo Headset. And connection is established.

BUT: I can't listen to music. I can read the title of the mp3 on the headsets display, turn volume loud on both devices, but no sound at all. hmm ?!
[Windows Phone 7 Q&A, Help & Troubleshooting] pieryx:
Hi,

I sent my phone RMA and the solved my problem updating the firmware (that's what they said). I could connect my phone to any BT device. After window-break it stopped working again.

No way to wait 30 days to repair it again (RMA).

Maybe the problem is related to something the window break modifies.

Any expert?
[Windows Phone 7 Q&A, Help & Troubleshooting] japmeet:
you mean to say that jailbreak breaks the bluetooth? well i have a dev account but regardless of the unlock status, my bt has never worked, i've given up on it
[Windows Phone 7 Q&A, Help & Troubleshooting] pieryx:
I'm sure RMA push new firmware (radio drivers) to the phone. Firmware we won't never get available. Zune updating the phone we lose BT again. It's a shame
[Windows Phone 7 Q&A, Help & Troubleshooting] japmeet:
let's hope the DFT rom fixes that issue. Can anyone using DFT on omnia 7 confirm if their bt is working? (like not working before DFT but working after DFT)
[Windows Phone 7 Q&A, Help & Troubleshooting] japmeet:
Guys, my Bluetooth Hardware and Software version is 0.0.1 can you guys (who's bluetooth is working) post yours? It'll be helpful in knowing what's causing the problem.
[Windows Phone 7 Q&A, Help & Troubleshooting] stevenmu:
Hi all, I have been having this same issue for so long as well. Hopefully we can find a solution.

One thing I would add is that it worked ok before Nodo. The quality wasn't fantastic, but that was standard for all WP7 phones, they used too low a bit rate. There was supposed to be a fix to increase the bit rate in Nodo, and it seemed to help with other phone models, but as soon as I updated I got the problem that all of you have with the sound not playing/skipping. So obviously something changed in Nodo that made it worse.
[Windows Phone 7 Q&A, Help & Troubleshooting] japmeet:
Hey, thanks for replying. Just wanted to let you know that my phone's bluetooth never worked. It always kept skipping (like a thousand times in a second). Nodo/mango nothing fixed anything. Also I used to have interop unlock & advanced config on my phone. Under bluetooth settings, I was never able to apply changes to bitpool, usejointstereo etc. It always used to give me an error "unable to apply changes". I navigated to the bluetooth path in the registry to find that the bluetooth keys were not present! I manually put the keys there but there was no change (though I was able to use the bluetooth settings in the advanced config after that) Weird.
[Windows Phone 7 Q&A, Help & Troubleshooting] stevenmu:
I think (but I'm not sure) that registry keys can have permissions applied on them, and that this can change from manufacturer to manufacturer. Some keys just won't show up for some registry editors because of this. I had tried editing the entries before too and like you I couldn't see them at all. I think I read somewhere before that there was another registry editor which could access all of the keys no matter what permissions were applied. I'm going to try and check into this further over the weekend, if I find anything interesting I'll post back here.
[Windows Phone 7 Q&A, Help & Troubleshooting] japmeet:
I tried using two different reg editors and I didn't see the keys in both of them but what you said sounds reasonable. Also I had a interop unlock and not a full unlock so maybe that might be restricting the view. Anyways, good luck hunting!
[Windows Phone 7 Q&A, Help & Troubleshooting] stevenmu:
Full unlock could definitely make a difference, I've been thinking of flashing Ceesheim's ROM which has a full unlock any way so may do that first.
[Windows Phone 7 Q&A, Help & Troubleshooting] japmeet:
Okay do let us know what you find! :)
[Windows Phone 7 Q&A, Help & Troubleshooting] GoodDayToDie:
Yes, the policy engine can (and does) restrict access to some registry keys. That's why not all keys can be read, and no keys can be written, from a Sliverlight app directly. ID_CAP_INTEROPSERVICES allows the use of high-privilege drivers to modify the registry, but typically those drivers don't have the listing/enumeration APIs for the registry, so browsing is done using the low privileges of the app itself.

The only ways around this are to either write our own driver (some effort to write, extremely difficult to make it work on a stock ROM), use a per-app elevation of privileges (HtcRoot project, WP7 Root Tools v0.9), or use a fully-unlocked ROM (which means the policy system is turned off, so all apps run with maximum permissions).
[Windows Phone 7 Q&A, Help & Troubleshooting] stevenmu:
It took me a while to get the chance to do this. I flashed Faria's Tango ROM, I went for that one because it specifically mentions bluetooth profiles.

I tried connecting it to my car headunit and the normal problem existed (I could hear calls ok, but music wouldn't play, skipped etc).

Using the WP7 Root Tools registry editor, I was able to see the registry keys listed above, and to edit them. I've tried setting the bitpool and usejointstereo values to to some of the values mentioned above, and now I can't connect to the headunit at all.

I'll keep experimenting and see if I can get it to work, but flashing a new ROM doesn't appear to be the silver bullet that I'd hoped.
[Windows Phone 7 Q&A, Help & Troubleshooting] japmeet:
thanks for the update! though it's not a full solution but it will give some hope to a lot of omnia owners! :D
[Windows Phone 7 Q&A, Help & Troubleshooting] stevenmu:
Ok, I don't know what happened but this appears to be working perfectly now. Earlier in the week I tried again and it let me pair to devices using bluetooth again. I was still getting the sound skipping problem so I tried editing the registry values again, I tried a few combinations that didn't work, but then tonight I tried Bitpool: 81, MaxBitpool: 81, UseJointStereo: 0 and it just worked. Music has been streaming perfectly since. The music quality seems a little flat, but that might be the headunit in my car, I need to fix the screen on that so I can get at the graphic equaliser.

But the main thing is it's working. This shows, in my case at least, that it was definitely a software problem, not a hardware one. I'll keep experimenting with values when I can and see how that effects it.

edit: Looking back through the thread I should have been trying 51 and 53 as the bitpool, not 81 and 83 :) I think by default it was 51, and UseJointStereo was 1, so I'll try with bitpool set to 53 next and see how that goes.
[Windows Phone 7 Q&A, Help & Troubleshooting] japmeet:
Ah, so you tried the tango rom? Well this does sound promising! I think I'll wait for the tango update to roll out officially & then see if anything changes, if nothing does, then we'll have your settings to try out!

Also tell us what changes did the new settings bring about?

waiting for CWM image
[LG Optimus Black] achyut:
@StiflersMom did you get 2 root it???
[LG Optimus Black] ontour:
Tried that and it didn't work. "Global" didn't work either.

Maybe because I'm on V10F PORTUGAL, but I'm downloading the KDZ.
[LG Optimus Black] StiflersMom:
No, didn't install the update cause i'm going on vacation tomorrow. Too risky having a buggy phone and no time this evening for installing and configuring 100 apps. Sorry.

Awesome, will check it out. :)
[LG Optimus Black] N00BY0815:
Installed now i only need to root it... what might be the best way?

DO u think the v10c way might work?

Thanks to all the developers.
[Nexus S General] flodb113:
This is nice. Also, it could be a good idea for roms. The only thing is to redo the benchmarks every once in a while, as the developers keep updating. Great work!

Transmitted from somewhere in space... from my Nexus S... and Tapatalk.

Steve Garen's kernel seems to have the best benchmark results. Anyways thanks for this I was curious about this but too lazy to do it myself.

[Nexus S General] bedalus:
I'm not certain, but I believe the performance of the kernels may be compared directly so long as the testing circumstances remain absolutely equivalent.
[Nexus S General] brenix:
Very cool to see.. Nice work bedalus
[Nexus S General] Wir3start3r:
Thank you!
[Nexus S General] flodb113:
You're in for a lot of work, but I don't think it's necessary to update after each of the kernels in updated, just on a periodical base:p (of course, you have a life and that comes first)
[Nexus S General] steve.garon:
Cool comparison. Tells me that I can improve 2D and 3D score somehow...

Be careful when you read IO scores. There are some tweaks to improve IO that give better benchmark result but poor actual performance while loading app. Benchmark don't tell the whole story. ;)
[Nexus S General] suksit:
I just think there may be some more variables to control e.g. SG kernel runs at 1.1GHz by default :D
[Nexus S General] bedalus:
Thanks, I'll add that to the information in the notes. Cheers Steve!

Great charts and scores, thank you :)
[Nexus S General] tupac19861013:
Cool work u have put in buddy, keep it up.....!!! Cheers....!!!! :)
[Nexus S General] tchaari:
Great work thank you so much for this Benchmark. Adding battery life comparison will make it absolutely perfect but I think it will take a lot of time to be significant (minimum 2 hours for each Kernel at the same conditions I think).

Thanks again for this good work man ;)
[Nexus S General] steve.garon:
Yeah... Adding battery life would just take forever and there is too many variables.
[Nexus S General] tchaari:
Yes but it is not that difficult to do. I am thinking about a full battery charge, flash Kernel and let it idle for 2 or 3 hours. Than just note the remaining battery charge.

Full recharge again and the next Kernel... Maybe just doing it on 3 kernels takes a complete day :D
[Nexus S General] IIIV:
Do any of these benchmark apps actually support ICS?
[Nexus S General] kd.fadi:
thanks

very usefull work
[Nexus S General] :
Okay, this is mainly technical detail for tchaari.

I retested kernels from netarchy, terryhau, peter alfonso, Reddv1, and the stock kernel. All set with ondemand min=max, and deadline. I/O scores improved:

Netarchy -17% to 3%

___________________ = +20%

Terryhau -21 to 0%

___________________ = +21%

p.alfonso -17% to 1%

___________________ = +18%

Reddv1 -3% to 6%

___________________ = +9%

Stock 101% to 111%

___________________ = +10%

It's improved the consistency of the results, as you can see by comparing the stock(ish) kernels.

I will leave mathkid95's matr1x, steve.garons SG, and r_data's Air Kernel, because I'm expecting updates from them relatively soon anyway.

Due to this, I think I should re-do my variability tests, because I was using speedy-4, and I can't remember if it was deadline by default. Also, it was not set to min=max. I may be able to get the variability down further. I will work on this today.
[Nexus S General] tchaari:
Oh ****, I've ran out my 8 thanks today lol.

Well, this is very good dear bedalus. About the updates, you can add Eugene's one... Speedy-6 will be out soon too :)

I hope he will fix the USB/Wifi tethering... Just be sure to switch governor and the I/O scheduler as the others (default will be smartassV2 again I think) ;)
[Nexus S General] :
Yep, as soon as he makes it public, I'll add it. Don't worry deadline/ondemand-mix=max from now on! :)

UPDATE: To reflect the change in the way I test kernels (from always default settings to always deadline scheduler and ondemand with min set to max) I have recalculated the variabilities of the tests using these new settings. They didn't change much. CPU and graphics got more accurate, RAM stayed about the same, and I/O got slightly more variable. Probably wan't worth doing, but in the interests of consistency and scientific rigour...
[Nexus S General] :
Trawled through my own thread to find this. Back on the 16th i finished adding SQL scores, and then incorporated them into the overall I/O score, but stupidly forgot that a lower score is better, so for a week bad scores were improving results to a marginal extent. Only noticed when Franco's kernel got released and scored great in SQL, but the overall I/O score was low. All sorted as of yesterday.

As of today all kernels in the list have been tested in the exact same conditions, including user definable parameters, such as scheduler and governor (see today's earlier post), plus if things like BLD BLN etc. are incorporated they will be deactivated.

Thank you for add my air kernel:)

Could you add SIO Scheduler in kernel features?

Default scheduler is SIO.

[Nexus S General] :
Coming later tonight: comprehensive comparative I/O scheduler benchmarks for bfq, cfq, deadline, noop,sio, and v(r)
[Nexus S General] :
HUGE UPDATE: You don't want to miss this if you are wondering what I/O scheduler to match up with your preferred CPU governor. http://goo.gl/iJXWI

This took a whole day of testing! But I think the results are worth it. Scores are based on a geometric mean of overall performance in I/O and variability of scores (lower variability scores better).
[Nexus S General] :
UPDATE: Three kernels updated, Eugene373 ICUP-3.1.10 speedy-6, and Steve.garon's SG High Hz and Best Colour versions.
[Nexus S General] rosms:
amazing and time consuming job you did mate. really apreciate it. thanks
[Nexus S General] Jamalsid:
Thaks for the great work.

I don't suppose you have plans to add more schedulers to the list?
[Nexus S General] :
Thanks, I can't add more. Partly because it's so exhausting! Mainly because of technicalities. There aren't any other schedulers available in any of our kernels, and even if a new scheduler got added to a kernel, it would have to include the schedulers I've already done, and I would have to retest them all, otherwise the environment would have changed, and it wouldn't be a fair test!

I think there is also a chance you mean governors? If you are thinking of something like Ezekeel's new Wheatley, that is a CPU governor, different to an I/O scheduler. :)
[Nexus S General] aLNG:
u forgot lazy gov...
[Nexus S General] asphantix:
thanks bedalus for your great work

maybe you could add lulzactive (v2) to the schedulers benchmark? Would like to know how it performs with sio or cfq :)
[Nexus S General] :
I'm pretty sure lulzactive would perform like smartass, they are both versions of userspace. But I'll consider it, and lazy perhaps.

For kernel benchmarks and more, see here: http://goo.gl/mpeHI
[Nexus S General] krasnoff:
bedalus, you're doing great and necessary work!

After all these tests, you already have a strong opinion about the best combination of i/o scheduler & governor?

The best - I mean performance and energy efficiency. I know the answer is not easy, but... what do you personally prefer?

For example, I think the best combination is VR+LulzactiveV2 (tuned to a specific purpose), but may be I mistaken.

Thanks!
[Nexus S General] :
great work, thanks!

btw: Matr1x kernel has an update
[Nexus S General] :
Thanks, but that was done yesterday! :D

For kernel benchmarks and more, see here: http://goo.gl/mpeHI
[Nexus S General] :
Eugene asked me to to investigate v(r), and initially i was impressed, i mentioned the result to Franco, and he warned me that the peak throughput isn't reliable. It's part of the reason i did the study into schedulers. Indeed v(r) didn't do well. I believe (i.e. my opinion :)) the best combination is smartassV2 and deadline. Although conservative and cfq might give some battery savings. I'm hoping to study this soon.

[Nexus S General] mobile_pc:
@bedalus

What kernel are you using as a daily driver? :)
[Nexus S General] :
I'm afraid I can't say! I haven't been using my phone as a phone since I started running benchmarks on it almost continuously! Also, I started this study to help me try to figure out which had the best performance, but I have discovered there is more to a kernel than performance. Some people might not be able to live with that green flash for example. Some might need all the mods and features to help them customise their experience. I think user experience counts for everything. I hope this information adds to peoples' experience. But I don't want to say, "use X because..." or "Y because..." --- I just think that would take some of the joy out of it. I hope that's a sufficient answer!
[Nexus S General] steve.garon:
Completely agree. This is why I like how all the kernel are different! And at the end of the day, if your don't like the kernels available, build your own, this is what I did :cool:
[Nexus S General] :
Update, lulzactiveV2 added to schedulers chart. Winner, sio, close second, cfq.

Lazy coming tomorrow!
[Nexus S General] y3mita:
Indeed SIO-LULZACTIVE are super fantastic COMBO!!
[Nexus S General] simms22:
good question
[Nexus S General] cspader:
hmm wondering why you labelled smartassv2 as winner in the governor sheet. isnt performance the highest scored? thx
[Nexus S General] aLNG:
u cant use it as daily gov (cpu always at max -> huge battery drain)

so almost ideal gov with balanced is smartass2
[Nexus S General] cspader:
oh i didnt know that... found more info in the governors link. THANKS!

bedalus, have a couple of questions for oyu

1) since you used different kernels in governor and scheduler tests.. what can you comment on about the choice of kernel in governor/scheduler performance scores? does it vary much? basically comparing (stevegaron/smartassv2/cfq) vs (eugene/smartassv2/cfq). which leads to the next question

2) since each governor has its best scheduler as seen in scheduler sheet, do you find that the governor sheet is redundant now? ie. the best scoring (realistic) combo right now would be ondemand/sio instead of smartassv2 (the winner in governor)?

edit: another observation

(eugene/ondemand/cfq) is better scoring than (eugene/smartassv2/cfq) while for stevegaron, its the opposite.

hope i'm not missing anything important. cheers n happy testing!
[Nexus S General] :
Really great and useful observations. I'll have a think. But i can say now that i plan to repeat at least one scheduler/governor combo on another kernel to see if the results come out the same.
