Possible Bluetooth Fix G2x - Works so far

Okay.. I know. This is my first post, but don't use that to determine the validity of the information.
I've been on here for months, just didn't have anything useful to contribute until now.
Switched from rooted Gingerbread MT3G to G2x - was pretty excited till the bluetooth issues set in.
Didn't have the random reboots like everyone else. I think that happened once in my pocket... not thing to write home about there. This damn bluetooth was killing me though. Like a bad toothache badly in need of a root canal. Every time I picked up the phone I was reminded how beautiful but flawed this is.
So my search began. Poured over LG forums, T-Mobile and Google searches, compiling information. It became clear that this didn't seem like a hardware issue. The crappy Andriod 2.2 shipped with the phone was the issue. To me it seemed like this wasn't fully tested before shipping. Has sold tens of thousands of these phones and were largely unaware of the issue - the techs were surprised when the reports came in - mainly from US based customers on T-Mobile. In my quest I stumbled across an app that reported to fix a similar issue on a few other phones and gave it a shot, and it worked. So real simple here you go:
1. Root your phone, if you haven't already done so. I did with a heavy heart. Was waiting to do so but this issue was driving me nuts.. I used these scripts to Mac and Linux (I'm a unix guy):
http://forum.xda-developers.com/showthread.php?t=1048309
2. Download, from the market, and run, the following app:
>>>> Bluetooth Fix Repair <<<<
That's it!!
Here's what I did to test:
a. Left headset on, power cycled phone
b. Left phone on, power cycled headset
c. Out of range disconnect on head set, then moved back in range - successfully placed call.
d. Received call from a fresh connect, force range disconnect, then reconnect - successfully received call.
e. Disconnected headset from phone menu, then reconnected, placed call successfully.
f. Left headset and phone on for hours, multiple disconnect/reconnect - successfully placed calls.
I'm using a Blueant Q1, with the Blueant app from the market - BTW.
All seems to be well so far.. Give it a shot

What were the issues you had? My bluetooth seems to work fine, except the volume seems low and of course it helps to drain the already short battery life -- sorry, don't mean to be adding another battery rant!

My battery life is fine. Lasts the whole day and then some. Check the running apps and kill the unnecessary tmobile apps and anything else that you don't need. Another way to save battery is to drop the data rate down to 2G. Settings --> Wireless & Networks ---> Mobile Nets --> Use 2G. I know, defeats purpose of having 4g, but it works fine for email and IM.
Bluetooth issue:
Bluetooth disconnects and doesn't reconnect. Only way to resolve is to power cycle phone. Sometimes it would indicate that it was connected where it wasn't. Multiple folks have the same issue. Doesn't seem to matter whether it's a headset or car bluetooth.. same issue.

Wish I had the time to get into the ROMs. Don't know how you guys do it..

Returned the original G2x today and got another. Well, bluetooth is jacked on this one also. You know, I shouldn't have to be messing with this damn thing I paid $300 for. It should work.. The right thing for T-Mobile to do is recall the G2x and replace it the new dual core nexus for affected users. This phone is a piece of shyte.

The BT fix was short lived My bluetooth must have disconnected half a dozen times today. Very frustrating.

I have a Blueant Q2 that collects dust because it is useless trying reconnect it every time it disconnects (far too often) while I'm driving, what's the point? Bluetooth is a fail on the G2X.

So the damn bt issue is still not resolved.

ICS fixes the BT issue... but how? And can it be done for previous versions too?
I have tried the ICS CM9 and it seems to fix this BT issue. Not sure how it happens. Can one of the developers comment and maybe implement the fix in their ROM as well?

It works in the SK ICS builds.

I know it is an old thread but would like to share my experience here.
My only desire was to have the bluetooth not disconnect without announcing the disconnect. I saw this issue in GB 2.3.3 and below and saw it fixed on 2.3.4 and above, only to see another issue (no mute via bluetooth) crop up.
I have, however, by sheer luck and burning hours at it managed to fix it for 2.3.3. Haven't tried to see if it fixes the mute problem yet. I am satisfied with Weapon G2x 3.0 R1 .
Here is the link to my post. http://forum.xda-developers.com/showthread.php?t=1590523. Note that you will loose everything in the internal SD card so be prepared. It seems that the disconnect problem has its root in another partition (other than /data, /system and /cache). I have been problem free for almost 3 weeks now.
Will try with 2.3.4 and above later to see if the mute issue gets fixed too .
Try at your own risk and post results as you find. The reference thread in the post can be used to create an out of the box G2x with T-Mobile ROM so no chance of bricking (I believe this phone is unbrickable ).

All these new roms are amzing however, Hellfire Sandwitch and Pheonix both have this damn Bluetooth issue. I go to make a call and no sound comes to the bluetooth except some static and then it goes away. I hear nothing. I switch to speaker phone and I hear the dialtone on that. What the heck is going on with the bluetooth on these roms? Both ICS and GB share the same problem. I'm using that fix posted on the forums that makes any rom work with the new march 2012 BB update.

check the irl too?

No haven't done that. Not sure how you mess with the irl. I know it has something to do with baseband. But I don't think it has anything to do with Bluetooth?

[Q] SE Mw600 problems

So I had the SE Mw600 for my nexus one and it worked like a charm but after pairing it with the sensation. No buttons work. I just the the audio and nothing else works. I did some digging and it seems to work for the desire I wonder what is the difference? Anyone have an idea of why it wont work? or have it working?

It is working here as it should.

Works fine here too. I finally see Caller ID with gingerbread powered Sensation

Works here as well. Paired up fine. I could adjust the volume and stop, play and forward like when I had it with my N1.

So its just me... maybe I should factory reset the phone and see if that helps thanks for the answers guys.

Woah really? A factory reset for the phone just for a bluetooth pairing? Have you tried other options?
Like unpair and remove the headset from your phone and reboot. And for safe measure reset the MW600 as well.
To reset the MW600 headset
1 Make sure the headset is turned off.
2 Press and hold down POWER until the pairing indication appears.
3 Simultaneously press and hold down POWER and CALL button until the headset turns off.
Have you also tried other bluetooth headsets and do they work properly? I just don't want you to go through a full factory reset and have to restore everything in creation if you don't need to. GL
EDIT: And like with my n1, the tracks do not appear on the MW600 (but the caller ID function works) because it's a Sony Ericsson thing. But all the other buttons work without an issue.

Well I have tried everything. I reset the mw600 and unpaired it. I paired it again with my nexus and it works fine.
I haven't really tried other headsets because Well I don't have access to them. Except my bluetooth radio transmitter thing which works fine.
I searched around every other forum here and elsewhere trying to see if anyone had the same problem or similar but nothing. I've tried all the free players that they said worked and what not but really nothing works.
The really odd part is that the sounds comes out fine but none of the controllers work. which kinda make it useless in the gym.
I'll try to reset the mw600 again and pair it again and see if this time it all works this time. I know the factory reset seems a little bit too much for only the bluetooth thing but since I'm the only one having the problem I think it is the phone. Idk I'll wait a little bit more and do some more digging before I reset. Thanks for all the help.

I am not sure if this applies in your case, but are you on a non-US Sensation? Not sure if the others are using the US tmobile sensation or not. But I am using the Tmobile branded version here. Again, I am not sure if it's relevant in your case.

yeah mine is a Tmobile US sensation. for my luck after struggling with this thing all day yesterday today... I dropped my phone and I cracked my screen. This isnt my week at all. Called HTC and they are saying it will be 160 dollars to fix... Well at least that will take off my mind from this for a while.
*UPDATE* after factory reset to send my phone for repairs... I tried to pair my phone again with the mw600 and it worked fine... I guess there was just something wrong with the phone settings.

I use my MW600 with my t-mobile branded sensation and all works fine. I use it with xiialive and can skip stations fine and everything. The names don't appear on the display, but again like kpj says, it's a se thing.

Actually its not a SE thing but its a Bluetooth stack problem android uses a 1.0 AVRP version called bluez and track name support is only in AVRCP 1.3/1.4.
I found all this by doing some more research on the topic. So when we get an upgraded Bluetooth stack we will be able to see the track names. SE payed for the upgrade to enable this feature apparently.

Can we get the new stack with a custom rom?

yes. However, I've gone from one version of a rom to another and lost the functionality...and the chef could not explain why.
AFAIK, any rom that is remotely based on a stock one will not support song info.

[Q] Bluetooth commands HTC Desire HD plz help!

Hi everyone, I hope I am not wasting your time with this question but I have just gone out and bought a Q2 Blueant headset and I have a HTC desire HD, on the side of the box it says it works with android and the guy at the shop said it works great..........the thing is if I say phone commands it says this phone is not supported, I have installed Vlingo and it does not pick up on my voice unless i speak into the phone and it just does not want to use the headset even though in the box the headset comes with says to use Vlingo with it!!! I don't get it!!
I have made sure the voicedialer.apk works and it does but not through the headset either, is there something I am missing? its driving me up the wall!!
Cheers for any help everyone.

If anyone can help at all it would be awesome, the people at vlingo are just emailing me what info they have on their site even though I asked them not to do that.....probably why they are doing it and blueant still won't get back to me. Someone else has to have tried to use Bluetooth.....

Have you downloaded the blueant app? I have the Q1 and the T1 and they both work without issue. Also are you on a custom rom?

Thanks for the reply,
Yeah I have tried 2 custom roms now android revolution and core droid, I just want the headset to do more than answer and decline calls, I want full hands free feature with this thing, I have already gotten a $350 fine for using my phone so I bought the q2 which says it does all this and then when I say phone commands into the headset it just says this phone is not supported, I have gone through all the settings I can think of and nothing!
If there is a Rom you know of that will work perfect then Ill install that, I don't care what rom I am using I just want to be able to do my work while driving and any email I send to blueant or vlingo gets me nowhere.
EDIT: Yeah I downloaded the blueant app, it has done nothing for me unfortunately

Not real sure to be honest. I use it only for phone calls. I don't even have it read texts as that can be trouble causing. One of the main issues that when the screen is locked nothing will work till it is unlocked. What you are wanting may not be possible at the present time. Ill test a few things out on my end and see what I can find. But no promises

Cheers mate,
Ill be interested to know if yours works.
I did just get this email from Vlingo also.
"Hello
Thank you for contacting Vlingo Customer Support.
Our most recent 3.5 patch seems to have corrupted Vlingo's Bluetooth compatibility. We are currently investigating this matter and work to reproduce the issue you have reported to us. I regret that I am unable to provide you with a concise solution to resolve this matter at this time. Nonetheless, please be aware that our QA engineers are aware of the problem and will be testing to identify the issue. We hope to resolve the problem in a timely manner. If we are able to repair the issue, we will deploy the fix in a future version release.
We appreciate you brining this issue to our attention and apologize that our recent 3.5 build has caused issues with Bluetooth. Please let us know if you have any questions or concerns.
Best regards,"
But why my headset says my phone is not supported I still don't know.

One of the biggest issues I have found is the lock screen. Once locked it doesn't allow any commands untilled unlocked.

That wont bother me too much, when im in the car its connected to USB and it will be unlocked most of the time.

[Q] Bluetooth Unstable

I don't think this topic has been discussed before (I did do a search before posting a new one). If it has, please remove it and redirect me to the correct thread, thanks!
So, here is my problem: I have a HTC Sensation 4G phone and I was trying to pair it to my car (Chevrolet Orlando 2012) using bluetooth. The car told me to do a search on the phone and once it has found it, enter the code provided. So I did all that and it seemed to worked out fine. It said the pairing was successful and it was ready for use. Then, things started to get a bit weird. Every now and then, and I am talking like every 10 to 15 seconds or so, the bluetooth will automatically turn off (unpair itself) and then 10 to 15 seconds later, it will pair itself again. While it is unpaired, it will switch over to the OnStar Handsfree Calling Service. Does anyone have any idea why this is happening? My brother has an iPhone 4S, and my mom has the LG Optimus, and they both worked fine, no disruptions at all.

Does anyone have any idea what the problem could be?

Thank you for the reply, but no, I haven't installed any custom roms before since I don't even know how. I am currently running on Android 2.3.4 and HTC Sense 3.0, software number 1.45.666.5

I have contacted GM about it and they are saying that it's a problem with a lot of phones and they are working with the manufactures to rectify the problem. They have no time frame nor are they very willing to contact you if they solve the software problems. My husband just got a 2012 Toyota Yaris and his HTC Sensation 4G works perfectly! My brand new Chevy Cruize does the same exact things that yours does. Please post if you find out anything more, and I will do the same.

[Q] Bluetooth Question

Ok, so I have an issue with my One X that I didn't have on my Galaxy Nexus. I was able to leave my bluetooth on (on the Gnex) all the time. When I got in the car, after a few seconds or so, it would connect. I never had to think about it. This was on AOSP, CM, or AOKP. No matter the build, it always worked this way.
With my One X, it never connects automatically. I feel like there's a setting I'm not seeing that I need to enable to allow it to act this way. If bluetooth is on, I have to manually tell it to connect to the stereo. Sometimes I have to shut off the bluetooth radio, turn it back one, etc etc.
This is on Sense Builds, AOKP, or CM.
Anyone have any insight? I feel like this shouldn't even be a thought. I should be able to just leave it on and never think about it.

Wrong section. Q's belong in Q&A. Let the mods know so they can move this thread.
Its not you, its the phone, or specifically the Bluetooth stack. Certain combinations of phones and Bluetooth devices (like your car stereo head unit) just don't play well together. Its the same on my car, which is a 2012 Subaru Impreza with factory head unit (which I understand is made by Kenwood). It work fine (mostly, sometimes the steering wheel controls to skip tracks won't work) once its connected. But it won't auto-connect and has to be connected manually every time I start the car. For other people's car stereos, it may work just fine.
There is nothing in Settings that will fix this. Further, I've messed with some of the system files to see if that would help (which some have pointed out has worked on other devices), but no good. I've also hoped that HTC would have fixed the problem with one of the firmware updates (as they sometimes update the BT stack when they update the firmware). But I've tried various builds, including the recent Sense JB firmware's, and the same problem persists.
I've reported the issue to HTC back when the phone was originally released in May. HTC support walked me though the usual steps of factory reset, update firmware, safe mode. But of course, none of this worked, and they logged the issue for further investigation. Aside from a change in the BT stack by HTC, I don't think there is much that can be done.
There are various apps and toggles and such that may make your life a bit easier (and others will likely suggest). And I'm using one now called Speed Enabled Bluetooth. But really, they are just half-a$$ed workarounds at best, and not a true fix. I wished the thing would just work like its supposed to.

As I already said, its dependent on the car stereo. Some will work, some won't. What make/model car, and is it the factory stereo or not?

My car is also a 2012 Subaru. its a wrx impreza, so we're in the same boat. guess its time to start looking into an aftermarket headunit.
