[Q] Bluetooth disconnect/sleep on lock screen [PowerAmp] [SOLVED!!] - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I m using ROM AdyScorpiusMIUI-GB[2.3.7].
However I have a few issues and the main one I have not manage to solve is related to disconnection of my Bluetooth headsets when the lock screen is active or being idle for a minute. I dont whether its because of software (MIUI/kernel/baseband) issue or hardware malfunction issue.
I have tried to search for it but have not found any info. If I missed some thread then feel free to direct me to it.
Symptoms;
Headset disconnects when screen goes black.
Turning on the screen (so you see the lock screen) turns Bluetooth on.
Phone;
Galaxy S2
I have tried the following kernel versions;
Androdi : 2.3.7
Baseband : I9100XXKP8
Kernel : 2.6.35.14-Siyah-v2.6.12+
MIUI : 2.2.3
Bluetooth devices;
Nokia BH-503
I hope there is something that can solve this issue or that I just missed some setting since I really like MIUI,
Best regards,
Sauky

For those who has the same problem with me.
Here is the solution :
Problem occurred when im using PowerAmp with Bluetooth Headset in CM7 based Kernel or Custom ROM.
And the solution is :
- Do The "Clear Data" for PowerAmp Application
- Do The "Clear Cache" for PowerAmp Application
Menu (Setting->Program->Manage Applications)

Addes solution here :
Using an application like Wake Lock (hxxps://market.android.com/details?id=eu.thedarken.wl) and starting a service to wakelock the phone 'resolves' the problem on both Stable and Nightly roms.
From (hxxp://code.google.com/p/cyanogenmod/issues/detail?id=4794):
after some research it seems that poweramp doesn't explicitly start a partial wake lock when playing music.
Poweramp uses the AudioTrack class. reading through the api specs it doesn't seem that this class has a method to hold a partial wake lock (or even if it should do it automatically)
It appears that poweramp relies on drivers (possibly the audio driver) on the phone to hold a partial wake lock when music is playing. while that is true for lots of platforms (including samsung using the original firmare and many others) it doesn't seem to be true to whichever audio driver cyanogenmod is using.
I guess there would be two possible solutions, either this wakelock is implemented within cyanogenmod when music is playing or poweramp wakelocks when its playing music and releases when its done.

I seem to be having the same problem with my Bluetooth. But I have the problem when using a Bluetooth headset while making a phone call. The headset just disconnects about 5 min. into the call.
I'm running CM 7.1 and have power amp installed. Clearing the cache and data settings for power amp did not solve the problem. Inevitably about 5 to 6 min. into the call my Bluetooth just disconnects and I have to hurry and pick up the phone turn Bluetooth off and continue the conversation on the handset.
I really like the CM & MIUI ROMs, but this is a dealbreaker for me. I love power amp too much, and I need blue tooth. I guess I'll have to go back to one of the stock-based ROMs
Sent from my nanite enhanced neurotransmitters directly to XDA

I have no issue with a phone call so far.
Have u tried installed and running "Wake Lock" above from market? (hxxps://market.android.com/details?id=eu.thedarken.wl)

MW600 connection problems

Hi,
A couple of weeks ago, MW600 was working as expected. But at the moment, I've got connection problems. Is anyone experiencing anything similar, or do you have any tips?
I have tried restarting both the phone and the MW. The radio function works perfectly. I have tried renaming my phone.
Here's what I'm doing:
* Turn on MW
* Turn on bluetooth on phone
* Search for units -> pair the two units using code 0000 (starting from scratch, just in case)
* Phone states that MW is connected to phone and media sound
* If mediascape is playing, I hear ~1 second of media sound
* After 1-3 seconds, MW makes a sound (5 descending tones) -> the phone briefly states that MW is connected to media sound only -> the phone goes back to stating that the two units are paired (no connection)
What do you think?
Mine doesn't do that, so it's quite odd.. Do a full reset of the MW600 (manual here: turn off, press and hold down power until pairing indication appears, press power and call buttons simultaneously until headset turns off), delete it form the phone and try again. There's no reason for it to do that.
I found the battery life to be a bit short....10 minutes of streaming music and it shut off, all this after overnight charging.....I have repeat this 'issue' Friday night, Saturday and Sunday only to have MW600 dead at the office now
My runs 12-15 hours! Without any Problems.
Same, I can use mine for at least 4 days (about one and a half hours a day) before it needs recharging - are you using the right charger?

You press the buttons on the MW600 itself, not on the phone. Read the manual that I linked to, it's all in there.
hmm anyone else have problem with the ringtone playing thru the mw600? when the phone rings. i can hear it ring on the bt headset. but it's like play a bit.. then i hear a beep.. then it plays a bit more.. and beep it's like intermittent
The beep means, that the headset is changing from the mediamode to the telephonemode.
Update... The problem above came back. If seems related to using bluetooth and wifi simultaneously. Whenever I'm using BT and enable wifi, BT gets a lot of problems and usually shuts down. Does this happen to anyone else?
Also, in the past I could use the buttons on the headset to change songs etc. That doesn't work anymore, even after resetting the headset etc. Is anyone else experiencing this?

Update... Problem keeps coming back. My supplier suggested that BT and wifi might interfere. I'd be very surprised if a "smartphone" cannot play music over bluetooth and surf using wifi at the same time. My supplier promised to check it out and get back to me... That was ~2 weeks ago.
Is ANYONE else experiencing the same problem? Can you listen to music over BT, then enable wifi, connect to a network, and keep listening to music over BT?

I have wifi on 24h/day and most of the time i don't have any problems but sometime they get disconnected and i have to turn off/on BT and everything runs fine after.
I will have to try without wifi
Bluetooth and Wireless LAN (WiFi) both uses the same frequency space (~2.5 GHz)
Most of the times Bluetooth should be smart enough to adjust the frequency to co-exist with WiFi devices.
If your area are crowded with other Bluetooth devices and WiFi access-points, the Bluetooth set might having trouble settle on one quiet frequency, and might just sit there trying to switch frequency all the time, never finding a good frequency to settle on.
To help those poor Bluetooth devices along the way, try to change the WiFi access-points channels to create a free channel where the Bluetooth devices can settle on.
Also check if your WiFi access-points have a "Co-exist with Bluetooth" option, and enable it. It will however reduce the frequency-width and therefore the bandwidth slightly on the WiFi, but Bluetooth devices should work with less interruptions.
Connection problem with s60
Hello!
I have an MW600 as well - using with an s60 symbian nokia (6650 fold).
It works corectly when using in bt mode and listening music from the phone, but it alwways lost connection when turm the handsfree to radio. When listening radio, zthere is no connection, no way to get the calls or answer.
Do somebady have the same problem or somebody know how to solve it?
I did reset on mw600 and paired again, but i have the same problem.
รก
i haven't had any problems with my MW. i always stream music from my pc via wifi to my X10, then to my MW via BT, witch is connected to a Reciver for party.
have you tryed restarting your MW after pairing.
My problem with this headset is that it doesn't:
1) caller name not displayed on incoming calls
2) Music/Mp3 tags not displayed on lcd (using Poweramp)
3) why does the phones itself rings not the headset just some beeps. Embarrassing when phone rings and then answer on headset.
Resetted but not solved any problems.
Wildfire running Wildpuzzle 0.8 with kernel 4.1 overclocked
Ok I m using mw600 stereo bluetooth headset with CM 6.1.3 V4.4 rom for 2 days now. The pairing is easy but the issues that I am facing are;
* phone has crashed/rebooted couple of times while pairing/ unpairing.
* besides first fact, it pairs without any problems and very easily.
* I have used it with mixzing and doubletwist media players. In both cases the music lags and sometimes the lag/pause is about 2-3 seconds long.
* incoming call shows phone number only, no contact name.
* voice dialing works.
* when I m listening to music or not listening to music on incoming call the headset converts to phone mode fine but after the call is finished, the headset doesnt reverts back to media mode that is, the music doesn't plays again and I tried connecting and disconnecting again but only way to make it work again is restart the headset.
* battery is so far ok for the headset. Infact I runned out of my phone battery while I was trapped in underground and listening to music.lol
* even the headset is connected, if I play youtube video, the sound comes from the phone speaker. In order for it to come from headset I have to play some music from using my headset controls and then play the video and then pause the track. This also happens with music app aswell sometimes. Like the headset is connected and if I play the song using my phone, it will play through phone speaker and I have to pause it and play it using my headset controls in order to listen through my headset.
So far its oki but its annoying the laggy music thing. It only occours in music playback, I spoke to my mate on phone for couple of hours using this headset and both ends could listen loud and clear.
i also paired it with my inspiron duo tablet and its working flawlessly....so anyone have any work around of the above mentioned problems? anyone facing the same problems? is it because i am using custom ROM? i am ok with the headset not showing song tags and stuff but music being laggy is not acceptable...because thats what i bought it for!
Any help would be much appreciated?
thanks

[Q] ICS XLPQ Bluetooth streaming problem.

Hi all,
Since i've installed the official ICS rom on my phone i have one major issue.
When i stream music over bluetooth to my car hifi it lags, well it's worse then lag i cannot even hear the music it's like constantly stopping and playing like if someone was spamming the start stop button. I never had this problem with GB 2.3.6.
I somewhat found a workaround but it's rly annoying to keep doing this to hear music. What i do is just when i connect to my car hifi i start playing with the volume rocker buttons so i can hear it trough my car, when I'm doing this i press the play button on the music player then it works fine until i stop the car or go to FM and go back to BT
This is definitely software related because the workaround i just described makes it work again :S. I don't want to go back to GB do you guys know the cause of this and do you maybe have a fix? Is this issue solved in the newer version of ICS XLP2? All i saw is that all of them have the same kernel so i did not upgrade.

I'm having exactly the same problem. I've never used 2.3 so cannot say if it's a 4.0 problem but it certainly looks like so..
I'm running resurrection remix 10 and use it on a Toyota TNS510 system..
Just a notice that this seems fixed for me now.
I've upgraded to the 4.0.4 Rom found here: Click!
Next to this i'm using the app "doubleTwist"
ICS talks a different language then gingerbread when it comes to A2DP, especially for the play/pause commands, which seem important to me..
Has anyone made reference to what the cause of the bug is in their code logs???
I did not find any solution for this problem. Some apps like poweramp have a solution internally which reduces my problems a bit. But when i use tune in for instance i still get hickups. Im using F1GalaxyNexus AOSP rom at the moment.

[Q] Audio Stutter when in lockscreen - wifi connection disconnection

Hi,
I've search the forum for a problem similar to mine but don't find anything that matches quite right.
When I listen to tracks (headset) and keep the phone on, there is no problem. If I put the phone in my pocket then when the lockscreen activates I start to hear stuttering. It does not matter what audio app I'm using, it can be the stock player, or my podcast player - of which I've tried a few -all with the same problem.
After some further testing I came to the realisation that this issue is not only related to lockscreen, its related to wifi as well. When I'm traveling on the London underground which is now becoming wifi enabled, everytime I enter/leave a station the audio playback starts to stutter. If I push the power button to reactivate the screen it starts playing perfectly again. The stuttering only occurs when screen is locked or device is sleeping or whatever we call the mode when it turns off the screen.
When I leave the house while listening to music, I get exactly the same problem, as soon as I get out of range of my wifi connection it starts stuttering. Once again reactivating the screen immediatley fixes the issue.
When I turn wifi off during my travel there is a noticible improvemenet to the amount of stuttering I get, but not always completely gone, which leads me to believe it might be related to any connection / disconnection including 3g. Or maybe that the wifi issue is incidental rather than causal.
The sound resumes normal playback after anything up to 10 secs of stuttering. It really makes listening to music or podcasts while traveling to/from work quite irritating.
I had this issue with 2 different builds - the original stock build from T-Mobile - and is still the case after using Odin to upgrade (downloaded from here) to
baseband: I9300XXDLID
Kernel: 3.0.31-368423
Build: JRO03C.I9300XXDLJ4
Phone is not rooted.
Does anyone have any ideas, suggestions of fixes for me. Would really like to listen to tracks without having to keep my phone in my hand and draining my battery unnecessarily.
Thx for any help....

Issue with phone getting stuck on bluetooth for audio

Hi guys,
I've been having this weird issue for some time, and it seems to not be related to any roms that I run, since it has happened on multiple roms. Here is my issue: I connect to my car's bluetooth to use things like Pandora, Music, hands-free calling, etc. When I disconnect from my bluetooth, however, my audio still thinks it is connected to a bluetooth device, which I can tell by when I adjust the volume since it has the bluetooth icon instead of a speaker. I have tried turning bluetooth on/off and closing apps and whatnot with no luck. I even tried stopping the music app and turning off bluetooth before I shut my car off, still the same thing.
Do you guys have any suggestions, or has anyone else experienced this? Normally a reboot will fix this, but my current rom locks up sometimes when I reboot, which is a pain since I have one of those Neo Hybrid cases on my phone.
Thanks,
Steve
I had a similar issue with my s3 last year. I believe I fixed the problem by going to settings> application manager> all (2 swipes to the left), scroll down to "Bluetooth Share", then clear cache & data. Hope this helps. You'll have to pair your Bluetooth devices again.

Bluetooth Audio issue

I have this little problem with my new Huawei.
(I have a Mate 10 Pro, couldn't find a section for that specific model)
Whenever I connect it to my car or Bluetooth headphones, the audio from my phone will randomly switch from my car speakers or my headphones to the phone speakers. The only way to get it outputting audio through the Bluetooth device again, is by reseting my Bluetooth connection. However, it does this every time and its driving me insane.
Can someone help me with this? Thanks in advance.
Hello
Try to remove all bluetooth devices associated on your phone.
Then associate Bluetooth with your car
Do not try to associate other devices for the moment.
Then try to listen music from your car to speakers of your car
If it's ok, then associate other devices and try again to watch if all is allright
This is a known bug that has been around since release, there is nothing you could do to fix it.
This is by far worst Bluetooth implementation I ever saw in android
On top of Your problem mine stops sending call logs to the car randomly and restart or re pair are only option to mend it
So strange ! I'have never had problems with bluetooth audio with my car !
Except if decide to receive the conversations sound on my Bluetooth smartwach.
Android don't like to have 2 bluetooth devices connected for sound at the same time
All the top cell phones are having blue tooth issues...just google it. It is not unique to this phone.
I have the same phone and issue and this is still not fixed ! Has someone found a workaround?
My mate 10 Pro works fine in my car, no issues at all. It works fine on Android Auto too. Yet in my parents' car, Android Auto won't work at all; I just get a black screen.
I guess these problems are often between two specific pieces of hardware rather than a general fault with the phone, so quite difficult for manufacturers like Huawei to fix everything. But if I had my parents' car, I'd be pretty pissed!
This is a known issue with EMUI and it has to do with EMUI killing processes in the background in the name of battery optimization. If your music player is in the background or your screen is turned off, EMUI will situationally kill or freeze bluetooth/audio related processes.
If rooted, use either Titanium Backup or Service Disabler to freeze/disable the Power Genius app. This app is responsible for EMUI's battery optimization measures (but the battery life on my Mediapad improved when I disabled it). If not rooted, you might or might not be able to do this via adb.
Other solutions include plugging in a charger, or leaving your screen on.
(edit - you have to reboot after disabling Power Genius, merely disabling it will not immediately change anything)
