Galaxy Tab freezes with bluetooth accessories [SOLUTION]

Just wanted to throw this out here in case anybody else runs into this problem. I just purchased a bt keyboard, worked fine for a few days, then suddenly my tab started to freeze, even after rebooting. System panel would show full cpu usage, and it took minutes to simply scroll, but the time and charging indicator worked in real time. After some searching I found some troubles the tab had with bluetooth devices. To the point, I found that after opening pandora for the first time since I had the keyboard that the bt media setting was enabled, turned that off, rebooted, and its been at least 5 hours and haven't had a problem since, usually only took a few minutes to freeze after powering up. As a side note, I'm sure other apps/settings may cause the same problem.

I use(d) bluetooth headset and my freezing problem was with any and all music players. I have Pandora installed, but is it only the setting in pandora that's the problem or all music players?

It could be any apps really. For me it was pandora, I'm using poweramp for my music and I know that has bt disabled. I would just check any media apps for bt settings.

Thanks
I noticed that the 'Bluetooth' was the cause of my GT-P1000 freezing issues.
But I didn't know that some apss could also cause this!
I will try to uninstall Pandora and see if the BT issues has been resolved.
It's annoying coz I often turn the BT ON coz I used it as my primary phone number

So since you changed the BT setting in Pandora, have you had any freezing issue at all? My device started freezing like mad and I couldn't for the life of me figure out what it was. I first deleted unnecessary apps, no effect. Then I formatted the memory, followed by a factory reset when the format didn't work. The problem persisted! Two constants in the equation are the presence of Pandora (which I did not realize uad a BT setting) and my Apple Bluetooth keyboard. I finally put two and two together that it had to do with my keyboard, so now I'm a bit wary of even pairing it again lest I smash my Tab against the desk in a fit of freeze induced anger.
So I am interested to know if yoir correction of the Pandora setting seems to be a permanemt resolution.

Notice the typos above? That's because I'm not using my Bluetooth keyboard. Haha

Helps alot, thanks.

Yep. Pandora. As soon as got my new Jawbone ICON Hero bt earpiece I decided to try it with my media players. with XiaaLive it was fine. Audio was nice and clear. Starting and stopping the app was smooth. However, when I tried Pandora, audio was fine and starting the app was fine. But every time I tried quieting the app my US T-Mo Galaxy Tab would get super slow. Everything was going in slow motion. Folders would take 20 to 30 seconds to open. Even pressing the Power button took about 15 seconds to show the "Shut Down" screen.
After a reboot, everything was fine again. And I left it alone until the next day when I tried it again. And sure enough. Upon quitting the Pandora app everything got really really slow again.
So, using Pandora and a BT device seems to be the issue.

I find that on the odd occasion my back button or home button becomes dead. This usually fixes itself immediately when shifting to another screen or something. A minor inconvenience.
Other than that I've not experienced anything else.

o2 v1.27 firmware

I had a weird issue in the car the other day
I was using the USB plugged into a Fiat 500 which has the Blue & Me system. I wasn't particularly bothered about having sound through the speakers, I just wanted to charge.
The stereo turned on anyway, and I was having random directions given through the stereo, with the Highlight Video music in between!! And then the ACTUAL directions coming through the phone speakers. I just turned the stereo off but it was really weird
Martin

I've had problems with random restarts and WiFi not connecting/WiFI settings freezing. Not allowing WiFi to be switched off during sleep seems to have cured it.

HTC One M7 speaker
I got my new HTC one the othe day from Harvey Norman and I have noticed that the bottom one of the two speakers cuts in and out and if you press on it then it works, but this is for all audio has anyone had this issue or know why it is happening?
Thanks

I got my HTC One last week and the wifi signal is really weak. When I am at 5mt from the hub (virgin media) I bearly have a signal.
My boyfriend's Xperia Z (with known wifi issues) has more signal at the same distance.
Anyone else experiencing this?

Phone in pocket after call
I am surprised no one has reported this annoying bug:
1) Have the phone in the pocket
2) Listen to music via the provided headphones (same if you use bluetooth)
3) Someone calls you and you answer via headphones button
4) After you or the other party hangs the phone, the phone turns on in the pocket.
VERY annoying!!! Please report this bug to HTC (I already did)
Otherwise I just LOVE this phone!!!

Problems charging phone and file transfers.
Ive had my HTC One for just over 2 months now. Havent had any issues besides the back button not responding. But just the last few days out of the blue, i am unable to charge my phone using the provided htc micro usb cbale that came with the phone to charge my phone. Keeps saying to use supported cable or doesnt detect my phone at all. It wont even charge through the wall power point using the adapter and cable provided. Ive attempted using other micro usb cables from previous devices and still no luck. Only way to charge my phone is using the extend battery pack.But have to restart my phone before charge otherwise it wont detect usb connection.
I also unable to copy and transfer files from my phone to pc also due to the usb cable and detection issue.
Has anyone else here experienced the same issue?
If so,how did you resolve the issue?
ive contacted HTC Support and still waiting on a response.

Sounds like you have accidentally bent some pins in the connection, potentially hardware not software related. I'd return for exchange.

2G connection issues
I have no idea whether its my ONE's problem or of the connection provider........ I cant use my 2G connection, it connects and disconnects at its will........Is there any way to test whether my ONE has any problem?

Strangeness with touch screen sounds
I may be the the only one.... but I like a click sound when the touch screen is presssed for a command. This works alright on my Sensation (pyramid) but not on my new HTC (M7).
There is sometimes a very very faint noise about a second or more after touching the screen for a command, kind of a delayed reaction? Anyway no amount of tweaking volume controls or using any sound mod produces a decent loud click sound. I revert any tweaks after experimenting with them.
Setup; HTC M7ul - ARHD ROM (12 currently)
Any information on this would be gratefully received!

This has been annoying me for the past week...
When I make or receive a call people tell me that they hear me far away. People cant tell its me on the phone! Gonna try to clean the speakers with a toothbrush but this phone is fairly new, bought it in September...

Push Bug (Whats app, sms), htc stay in standby
Hey,
I'm new here and i hope, this is the right forum for my problem
I bought me a htc one a few days ago, and i've already root it, unlocked the bootloader, set it s-off. my recovery tool is twrp-2.6.3.3, and i have the ViperOne 4.3.0 with ElementalX-m7-10.10.1. for the rights management i use LBE_Security, exactly this Version: LBE_Security_RC_5.1.5446_A1_EN_VI_1st_12.20.2013.
Sometimes, 2-4 times/day, if i write with somebay via sms or whats app, and my handy is in standby and i get the message, my handy vibrates and the LED blinks green, and when i try to unlock it, with double2wake or logo2wake, my handy vibrates, but my display still is black, like it is still in standy. Music works, i can turn the volume higher or lower, and i can keep klicking the power button or double2wake or logo2wake, but my display didn't react. It only vibrates, wenn i click use double2wake or logo2wake. i have to click the power button and the lower-sound button to reboot my handy.
First i thought, maybe it is the kernel, because i used undervolt 800 and max cpu 1890mhz, so i install viper new and the kernel new, but without undervolt etc., everything stock. But the bug is still there. i have the same bug, if i start the camera app and close my htc via the power button, but without closing the camera app, the bug is there, too. this is something i can live with, but not the problem with push messages.
And i don't know how to contrain the apperance of the bug. yesterday i installed everything new, and i install lbe security master, too, but i think, i forgot to give him superuser right, because today apps pushed me things, but they weren't allowed to do this. maybe it has something to do with the bug, but today i realised it and set lbe as a superuser and then the bug appeared again. before that the bug didn't appeared. maybe it was coincidence, i don't know.
all i know, is that the bug has something to do with sms and whats push, and i'm not 100% sure, but i think it's not the fault of the kernel elementalX. Maybe it's LBE or Viper Rom's fault, or may something else.
Do somebody please help me? This bug is very annoying me and i don't know android very well, it's my first android phone.
And excuse me for my bad englisch, i am from Germany and i wasn't good in englisch in school

Sounds like you've set your minimum frequency/screen off to too low, increase it to around 800Mhz and see whether you face the same problems again.

There's a fix for the camera bug in Venom Hub/Addons/Other

Thank you for your answers
@spiralOut
Thank you, this add-on fixed the camera bug, I hope, it fix the other too
@n1234d
Do you mean the undervolt option during the elemtalx kernel installation? Because first I choose 800kHz, now I choose stock, I think the stock is higher than 800, right? And the bug still appeared.
And what I forget to say: I used the swift option from HTC, that i can write with swiping on my keyboard, maybe this has something to do with the bug, now today I deactivated it.

Xperia T no sound after unplugging headphone

Hello
I've rooted my xperia t to install a custom mod on it. But I haven't had the time for it to install it. Recently I started to use my xperia to listen to music more, and when I unplug my headphone, my xperia sometimes thinks my headphone is still plugged and doesn't play any sound through the speakers. So I've missed already several times my alarm. I use the standard in ear headphone of apple, the ones you get free with your ipod.
So before I install a custom rom, I want to know if this is because I rooted my phone or it is a common problem and how to fix it? I already googled it, but I didn't find anything useful. Can anyone help me?
Thanks
Greetings

Hello, this does happen sometimes on my phone too!!
This is not because of phone being rooted.
My phone is rooted too.
All you have to do, is re-plug the headphones in the socket and then take it out and this should make the speakers work,
If not, you can always reboot the phone.

Yes, I've figured that out aswell, but it's annoying. Sometimes I forget to check if my sound works, I set my alarm and it doesn't go off. AFAIK, it's a software problem, so wouldn't be there anything to fix this problem? Wierd, sony never released anything to fix this problem as other people have the same problem aswell. Now I'm afraid to install a custom rom on it due to warranty, as maybe I will have to bring my phone in to fix it.

Same bug exists with Xperia V

Yes, this same bug exists on my Xperia V as well. However, one would suspect it could be a hardware fault, mainly because if it was present on every Xperia V/T phone out there, there would logically be a LOT more uproar about it.
If anyone knows whether or not the actual cause of this, do let me know. Some people are pointing to Sony's Smart Connect as being the culprit, but I have tried both disabling all its features, and also editing the headset and headphone profiles to FORCE (=add actions) sound mode to normal and volume to a certain point upon removal of headset - no help. In fact, on my phone not even plugging the headset back in and out helps, I seem to always need to reboot.
Official response from Sony is "we cannot reproduce the problem". But it is relatively widespread.

Just to let you know, and I'm not 100% sure about this "fix", but so far so good.
I downgraded Smart Connect via Google Play ("uninstall", so all updates gets removed) and deleted all headphone and headset events in the old version (the Music on the go and Music at home events). Been using the phone for a day without the bug appearing now - so if you're willing to part with Smart Connect's features, this might help you too.

Hi thanks for the heads up. I'll look into this after my exams. Yes I'm willing to delete smart connect. Never used it and I should even look it up to know what it means

Two days ago I downgraded Smart Connect. Looks like that's the fix. I still haven't had the issue since I downgraded Smart Connect. Thanks for the tip!

This bug seems have been solved in coming JB 4.3 update (I'm using the leak for a while and no longer such bug)

Basically it's not a software problem and I know it's very annoying... The problem is in the jack hole itself,
Don't ever try to do a factory reset because this won't fix that bug
You can either clean it "hardware fix" (hard method),
Or download this app on Google Play here #adfly /1d8wfk# {sorry, the site is preventing me from putting links} "software fix" (easy way but you may have to open the app every time it is terminated by a ram accelerator like clean master or something like that)
Hope this works for you

Bluetooth is a load of s#!t, much worse than before.
I use it in my car, so I only switch it on when I'm driving.
The Bluetooth toggle option now takes longer to get to; a hassle when you just wanna get going.
So, I figure I'd make use of the Quick Throw widget on the lock screen. What a joke! You have to swipe down on the widget to first expand it, then tap on it, then input your screen lock unlock pattern (or equivalent). That then turns on WiFi and Bluetooth, and it searches for your saved paired devices. Seems to take longer to connect, too.
Last time I used it, though, I had to manually select my car for it to connect. When it finally did, I soon realised that for whatever reason my music was playing in order instead of shuffled (via the Walkman app), as I had it when I last played my music (after the update).
Also, whenever a notification came through (from Facebook), the music stopped completely. I had to press the play button on my car twice (as the first time registered as "pausing" the music, even though it had already stopped), and then when the song started playing once more, it was back at the beginning again!
Oh, and when I finish driving now (meaning my car is not running, along with its Bluetooth), the damn music continues to play, making me have to manually turn it off.
Argh. Kinda regretting updating, but it's early days and so I'm hopeful that I can find some workarounds.

And what about the re-mount reboot fix what would happen to it in the KitKat Update? This would do a bootloop for Link2Sd and folder mount users
And About rooting how will we root ? Will the CM Kernel work with the super SU zip?
There are many questions I can'T answer

I don't know if my comment is effective against this issue, but, just in case you guys don't have any idea about this
A Bit of A Problem, I Think

Why do we always get less features?
First, Sony decides to cut "Profiles" feature in 4.3. Then we discover "App-ops" is missing too.
And now no ART for 4.4. Add to that, the SD card restrictions!
Why Sony?

[Q] Is anyone getting awful bluetooth reception?

I have a pair of bluetooth earbuds that I use when I'm on the go, and ever since I got my new turbo, they have been constantly skipping and stuttering when I try to listen to music. It's totally ridiculous, the devices are only two feet away from each other, at most! Is anyone else having similar issues?

Hmmm, I wonder if it's motion based. I'm sitting in my room listening to it now and it's a lot better. Unfortunately that doesn't really solve my problem, though.

Rixanu - I think you're on to something... I'll give my "story" and hopefully someone a little more savvy than us can help figure it out.
I switched over from the good ole Galaxy Nexus about a month ago. No major complaints on the Turbo yet as we await Lollipop, with the exception of this Bluetooth issue. I have the Bluetooth paired in the car, and a set of headphones - music and everything worked perfectly on the GNex through the Bluetooth. Now, primarily, it's often choppy (mustic anyway) - for reference, when listening to music I listen via Google Play (all access or whatever they call it now). I figured the choppiness was related to the fact that the music was being streamed since most wasn't downloaded yet, but after very limited experimenting, I believe it must have to do with the physical Bluetooth radio. I had noticed in the past that when the music streams perfectly, a lot of times if I pick it up to check an email, text, etc., it becomes choppy, but thought that was strange since the RAM should be more than sufficient to multitask without choppiness. On my way home from a friend's, I played around and stuck my hand over various parts of the back of the phone, and would press the phone against my pant, etc., and could effectively interfere completely with the connection such that it would be only silent, and not even choppy. Yet, while the music wasn't playing, the track continued to playback on the device and when the music would pick up after I moved the phone, it would be 10 seconds or whatever later as if it had been playing straight through the whole time.
I haven't tested this theory too much yet, but I think combined with your issue, there's certainly something there. Unfortunately, I frequent these parts in order to find answers to these types of issues and don't have the solutions myself.
Do we have lemons, or is this issue prevalent?
I'm happy to provide more info to anyone that can help.
Thanks in advance!

I was having the same problem. It was so bad Bluetooth was completely unusable. I contacted Motorola and they sent me the following steps to try. I worked perfectly. Good luck.
Dear Michael
Thank you for contact Motorola tech support, i send to you the steps you have to follow up to clear the cache for you Driod turbo
Before you do the Wipe cache, please un pair the Blue tooth devices and forget it for the phone, after you do that follow the steps and do the wipe cache.
This will remove any temporary files that may be causing the problem, but will not delete your files or settings.
1. With the phone powered off, press the VOL DOWN KEY for 2-3 seconds then POWER key then release.
2. The device will display different BOOT OPTIONS
3. Use the VOL DOWN Key to SCROLL to Recovery and VOL UP Key to select (I think he meant POWER to select)
Tip: If the device reboots, you may have waited to long to make a selection, you will need to begin the process again.
4. The device will display the Motorola logo and then the Android in distress ( logo with Exclamation mark)
5. Press and hold the VOL UP key for 10-15 seconds. While still holding the VOL UP key tap and release the POWER key
Tip: You can try this step, holding the phone in landscape. If you are stuck on step 6, try a force reboot by pressing the Power key and Vol Down key, and start the process again.
6. The device will display additional menu options (Text will appear in BLUE)
7. Use the VOL DOWN Key to scroll to wipe cache partition and the POWER Key to select this option
8. The device will then perform the partition wipe
9. The device will reboot and start the normal power up sequence

I think Bluetooth stinks. Poorly implemented, stupid pairing issues, and poor quality. I have had very little success with Bluetooth on any device I have had.
Sent from my XT1254 using XDA Free mobile app

Found a Fix for the Stuttering BT issue. It's the dumb kernel on 5.02 that stutters the playback as soon as screen is off. I used a partial wakelock so the cpu stays active after screen off with this app. It works. No more stuttering. As for speakers that require high sample rate I just switched the cpu governor to performance. It's a workaround but the partial wakelock should work especially on bluetooth headphones.

Every time I drive away from my house and the phone loses wifi signal, the bluetooth skips really bad during the transition. Once I get far enough away, it usually clears up again. For my situation, it seems the wifi radio is somehow interfering with the bluetooth signal.
