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):

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?

Bluetooth issues in ICS? Post your problems and solutions!

Hey guys, I'm sure a lot of you are already on one of the ICS roms already. First of all hail all devs who have made our life better before official releases!
However I have seen posts talking about them experiencing Bluetooth problems just like I am right now and mostly mentioning the Music player stuttering and similar issues like that.
My problem is a little different. My aftermarket car deck worked perfectly with all the phones I have connected to, including my GB i727. However after I flashed the ICS my bluetooth connection kept dropping out randomly. Starting with the deck not auto connecting when I get in the car. Then after I manually connect "Phone" in the menu, it will MOST LIKELY disconnect after (on average) 2 minutes with the "Media" still checked (although the connection is not shown on either the icon in the status bar or the display of the deck). Weirdest thing is, sometimes it actually keeps on working after it connects.
I didn't think that would be a problem for me because I don't use Bluetooth earphones and I use my iPod instead of my phone to play music in my car. So I even disabled my Holo Music and my Google Play... I'm on Sean's SKY ICS 4.2D
I am just wondering if bluetooth misfunctioning is a common problem on all current ICS roms for our i727 or is it just the rom I am on right now? Because I drive a Manual car, the hand free in the car is actually very needed for me. So spread your wisdom on the bluetooth issues please!
Thank you!

my jvc car radio doesn't work at all with bluetooth sense updating to sky I c s. The stock I c s leak seemed to work pretty well however. Now the phone vibrates as if it's going to force close then disconnects the bluetooth within seconds of connecting every time.
Strangely, the radio does continue to play for a few minutes even though the radio and phone both say the device is disconnected. All kinds of weirdness going on here! I am going back to the stock leak as soon as I have time to reinstall all my apps for the millionth time.
On a side note, my monster bluetooth speakers seem to work flawlessly with all the roms i have tried. Seems I need an exterminator as I am over run with bluetooth bugs!
I am a programer. I wish I had the time to work on these and help develop these roms. The developers here are some truly talented and generous folks! After finals next week, I will try to devote some of my time to helping out this community which I gain so much from. Thanks to all of you guys! I can't wait until cm9 is in beta/release stage! That will be a dream come true!

Yep, same isdues.
Tried many things but nothing.
It worked, still does only on sky ice update 6, but the phone does not deep sleep, that's the problem so can't keep using that.
Hope official rogers will fix it.

Same here.

Bluetooth crashes almost immediately and the phone buzzes.
I use bluetooth for playing pandora or internet radio.
UCALC worked perfectly.
UCLD2 is where problems started for me.
I've tried both fixes listed in the SkyICS thread.

Hi
My problem with Bluetooth is pairing to the car auduo. The phone can see the device, recognizes the type and tries to pair, but after putting a code I get a connection refused error. Previously worked with stock and custom 2.x.x rooms. From is now a 4.0.4 one.
Any ideas/suggestions?
Solved by replacing Bluetooth.apk to 4.0.1 found at androidforums

Works fine in my Cayman S

Bluetooth is finally fixed for me in CM10.1. No more Bluetooth Keep Awake. No more hassle of disconnects.
VW RNS 510

Hi guys,
I have found in other forum, and it's working for me.
Break connection between car and S3, and delete devices both in car and phone.
Now try to pair them again but don't let car system to access contact and data in phone.
After I did this my connection is stable.
Guy who suggested this believes that Samsung sends too much data ( all accounts data)and car system freezes).
Hope this works for you too

[Q] Jellybean Roms & Bluetooth

Hello,
I have had some issues with Bluetooth on jellybean ROM and not connecting to my radio correctly to play music from my phone it never seems to connect and send the music to the radio just stays on the phone and was wondering if anyone else had had similar issues. Bluetooth works the way it should when i go back to ICS Roms, when i get in the and the radio is on the music will switch from the phone to radio with out problem might take 30 sec or so but will switch over
thanks

I know on AOSP there has been numerous bluetooth issues with different devices. I'm not sure if its because it's AOSP or JellyBean. More than likely its the same problem you're running into. What ROM are you running? Scan thru it's thread to see if there are any fixes, if not ask in the thread describing the device you're trying to connect.

thanks for the reply .... the latest one i was using was CM10 ....right now im using SynergyROM and all is working ok .... yeah i tried to post in the rom i was having trouble with but im blocked from posting since i don't have enough post undender my belt i guess lol

Yeah, I didn't notice at first, I was on my phone. You need 10 posts to reply to a thread in the dev forums. It's not very hard to come up with 10 quality posts tho. There's so much general discussion.
I do know for a fact that CM10 was having issues with car bluetooth's along with other devices besides earpieces... it's the ROM I've been running and following. I didn't pay too much attention to the bluetooth problems tho as my earpiece works fine and I don't have a car to hook my phone up too lol.

yeah i just started using it more so now ive notice , about the only time i have ever use bluetooth

[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.

My Touch 4g and the ELM 327 interface for OBDII data - BT compatible ROMs?

I've been cruising on cyanogenmod 7.1 for about 2 years now, and since the auto store no longer reads OBD II codes for customers, I decided to purchase one of the $10 Bluetooth ELM 327 devices off ebay, and use the Tourque app to read the data from my car.
The app works great, but it only works if you have a notification pop up asking to pair with the device, and I've only been able to get BT to work with this device so far with a 4.2.2 ROM --> http://forum.xda-developers.com/showthread.php?t=2204963 (only JB one I've tried). The other ICS ROM's I've tried so far along with CM 7.1 just won't connect. Has anyone else found a good ROM that works, or a way to trigger a bluetooth notification?
Basically, I turn on Bluetooth in all the ROMs, it detects the device, I select the device, and it says "Paired but not Connected" If you long press or hit the gear symbol, the only option is to "unpair". Pairing with other phones works perfectly fine, but with this device the option/notification to connect never comes up.
Anyone know of any ROMS prior to Jellybean that work with similar BT devices? .. Dunno if there is a way to trigger a notification; I do like JB, but once everything I need is working, my #1 goal is then responsiveness.
Any ideas/insights/experiences are much appreciated.

Have you tried any Sense roms?

Well, as it turns out, after I did a complete wipe, and was trying cyanogenmod 7.2 out, I was able to connect..... in fact, I'm able to connect on good ole 7.1 as well, and mytouchUXv3... which I didn't want to uninstall- seemed to have a snappier ui. I have no idea why I was unable to connect yesterday, but on whatever ROM i've tried today, if I start bluetooth, then run the torque app, then go back to the bluetooth app with the torque app running, and select pair/unpair/pair/unpair, it connects pretty soon. *scratches head*
One reason I stick to cm 7.1 is that I've read of many users experiencing diminished battery life with cm 7.2

Just to confirm, it ALSO works well with Vipertouch 2.1.4.
Buddy of mine passed me his cheap ELM ODB II Bluetooth unit, (he could not connect to it, since he had some chinese S3 knockoff phone).. Worked perfectly first time.
Paired no problem, and connected using Torque Pro and read quite a few of the sensors on my honda without an issue.
Thanks to all the devs for keeping these older phones alive..
