Blue tooth issues

I was trying to sync my g2x phone to my uconnect on my dodge. It dials but completely mutes the call. Then it s shutdown the bluetooth on my phone. I tried out on my wifes g2 and would reboot the phone when I tried to shut down the blue tooth. I had to reformat her phone to stop that. We have 2 g2x phones. Again will sync but crashes after that.

I can't even get mine to pair with my Subaru BT. It see it, tries to connect then says incorrect pin but doesn't even prompt me to enter one. Its like there is one already stored for it, but its never pairs since day one...not sure what's wrong. I've factory reset once too. Hmmm

I think there is a problem with the blue tooth in these phones.

Its connecting fine to my Samsung headset. I currently am using the bluetooth to watch a movie.

I just got the G2X myself and so far I'm blown away by it except for the BT issue....
I use my phone with NO ISSUES on my Jawbone Era, but the SYNC in my F150 doesn't like it.
It's strange, the phone drops the BT connection yet still shows (icon at top) that it's connected. But under settings it's not.
Once this happens you would think you could stop / start the BT but nope! Gotta reboot the whole phone.
Anyone have any resolution to the issue? Hoping that the new GINGERBREAD once released will resolve the issue.
I've noticed that it seems to be related to data though, seems that my SYNC trying to sync the contacts is when it flips out... I'm going to disable the contact sync and see if it stays attached. I'll post my results soon...

Works in my Infiniti, better than the G2 did. Do your cars try to find the phone or does the phone have to find the car? Mine's the latter. When pairing, the phone actually pops up "Invalid PIN" and then a second later it pops up a screen that allows me to enter the car's PIN. It's as if the phone's sending a PIN without me entering it. You might want to try setting the car's PIN to 0000 or 1234 and see if one of those two codes are what the phone's first trying to transmit.

I can go either way, find the car or have the car find the phone.
I'll try using default codes 0000 1234 as you suggested... Mine does connect and pair, but then later on just drops the car like a bad habbit and I have to reboot the phone for any BT device (headset or car) to reattach. Almost like a service gets locked or something....

Does anyone have a fix for this?

Less issues with the G2x on my 2010 Ford Focus with SYNC than with my Nexus S. It seems it doesn't always reconnect properly upon start up, even though the car thinks they're connected, but that is only streaming. Phone calls always work fine. The Nexus S had all kinds of problems if you had WiFi turned on.
*sigh*
My iPhone4 had almost zero with the BT, but every time a major iOS release came out, I'd have some connection issues. However, Ford would then release a SYNC update and everything would be fine again. I'm guessing that NO ONE is following the BT standard as closely as they should, and that causes issues.

The phone does seem to be half finished.

I have a 2010 F150 and I'm having the same issues with Bluetooth and this phone.
Initially it attached fine and downloaded my phone book but now it disconnects and leaves BT on the G2x in a funky state.
I'm kind of hoping that Gingerbread will have an update, but I don't know I want to wait that long. I'll be touching base with the T-Mobile store about this.
If you have any updates with your truck let me know. I'd be happy to only use this for the phone for a short period of time.

I synced my phone to my car on the first day w/o any issues.
The car's phone setup menu did not find the phone. I had the option to either choose a fixed pin or a random pin. I chose a fixed pin and then went to my phone to search for the car.
It found the car in seconds and I paired it with the phone using the pin I inputed initially from the car setup.
I was able to download my phonebook with no issues and it only took about a minute or less. It couldn't download my entire phonebook, but that was just because of my car's inadequate space. I'd imagine with a 12.5GB hard drive in my car that wouldn't be a problem, but oh well.
Also, phone quality is great, reception is great, the quality on the other end is great as well. The best thing is that the G2x actually notifies me during a call if I have an incoming call/text/email...something my G1 couldn't do while paired to my car.

What kind of car? The various head units have different Bluetooth implementations. My Infiniti (and I'm assuming Nissan's) work fine. We've heard that Ford and Subaru don't.

I don't know if those of you who can't connect have tried this but it might be worth a shot. Change the name of the phone in Bluetooth settings. Turn Bluetooth off and on and/or reboot the phone until that name sticks. For some reason, it would either go back to "T-Mobile G2x" or show that the phone had no name until it finally stuck.
The Bluetooth profile/stack in the phone is buggy. It'll either drop the profile completely or randomly drop a device. If I reboot the phone sometimes they come back and sometimes they don't. The profile for my car didn't show in settings but the car connected to the phone anyway. It will sometimes play phone sounds through my speakers or headset and other times it won't with none of the settings changed in any way.
I hope either an update or Gingerbread help stabilize Bluetooth.

Acura. So yeah it seems Infiniti/Nissan and Acura/Hondas are fine. Before I got the Acura I had a Nissan and it was able to sync my G1 w/o issues as well.

Yeah the bluetooth on this phone is a little funky when trying to connect to my kenwood kdc-bt945 system, whereas the nexus s worked much smoother.

Think it's a hardware bug for the Ford stuff? I'm thinking it's not, I'm thinking that it's actually a software issue givin the profile weirdness.
Perhaps one of the gods here will have a rom out soon with better BT drivers / managment in it then what's on stock. I wish I knew more about rom cooking cause then I could work on whipping up a batch of gingerbread cookies.
I miss my Sync and now debating on taking the phone back under remourse and going back to my Vibrant 3G.
Other than this BT issue I love my phone.

Given that someone else is having SYNC issues with this phone maybe I shouldn't return it under remourse for another one but simply wait and see what happens. Any thoughts??

Have you checked on Syncmyride.com for SYNC updates? This fixed a few issues I've had over the past 2 years with my Focus.

Bluetooth problem with your car? Please read

Do you have a problem with your bluetooth on your Samsung device working correctly with your vehicles bluetooth? Does it get disconnected? Does it not even pair? Does the problem seem to be occurring with the phonebook being downloaded? If you are encountering this or any other bluetooth related problems with your Samsung device. Please post the following like below:

I'm in contact with a software engineer at Samsung, we need to get this issue PROPERLY resolved. This issue is not with our car manufacturer (as Samsung like to put the blame on them), but instead with Samsung. Numerous models of their phones do not successfully pair or only temporarily hold a pair with vehicle installed bluetooth kits. I believe this to be a problem with the Bluetooth Phone Book Access Profile (PBAP) on Samsung devices specifically as all other model phones successfully pair with my vehicle.
Please post in this thread if you are encountering or encountered any issues!

I have 2011 ford fusion but I think the problem is from the cars not supporting the phones I had this happen with a droid x a Samsung fascinate a htc Thunderbolt and an iPhone 4 since I got the car a few weeks ago. Ya im a phone addict so what. anyways now it's happening with the charge exact same issue with each phone and ford has said with each one that it is the sync software that is picky about the phonebook.

No major issues here: 2011 Infiniti G37x
The only quirk I've noticed, but I've noticed it with all phones I've tried connecting, is that the Handset Phonebook doesn't download until you do one handset phonebook voice search. Could just be Infiniti.

No problems pairing with my pioneer avic z head unit.

BMW - Samsung Charge Phone Book BlueTooth Workaround
Fix for this is counterintuitive. When you start your phone or restart bluetooth go to Settings>Applications>Running Services. Look for the Service "BluetoothPbapService". tap it, then hit stop. This removes it from the list. The phone pairs and uploads the phone book without problems until you either stop and restart bluetooth or turn your phone off. I am looking for a developer who can automate this process with an app without rooting the phone. Hope this helps.

OK, so here's what I've figured out. My initial response regarding the 2010 M3 being perfect was premature, though I have figured out where the issue lies. When my Charge connects to iDrive the first time, everything works, as it holds the connection and the phone book downloads perfectly. It's on repeated reconnections when I get back in the car that the signal will drop after a few minutes. Only when I reset the Bluetooth radio within the Charge does it again hold the signal. My guess is that the Charge is caching some information that it shouldn't be, which is causing it to disconnect after a reconnection. Again, if the Bluetooth radio within the Charge is reset, the connection always holds perfectly.
Hope this helps.

Drops off all the time on the phone. Intermittantly downloads phonebook and dial history.. The audio portion works "most" of the time but also drops off. System is called "handsfreelink" in the car.
IT'S DRIVING ME NUTS!

Guys. Follow Doc's post in disabling the service PBAP in your Running Services. This has fixed the problem for me as of now. No problems with connections. You must do it each time you power cycle the phone though

For rooted users:
go to /system/app/bluetoothpbap.apk and rename to bluetoothpbap.apk.bak. reboot your phone and pair again with your car.
This worked PERFECTLY for me, it works exactly the way it should now and the phonebook/everything is all good.

[Q] oneplus one bluetooth problems

i've seen this being discussed a few times but with no resolve.I bought 4 oneplus one phones altogether.The first two were for me and my daughter bought a week apart.
These have worked flawlesly and both have been rooted both connect to the bluetooth in the car with no problems.
I then ordered one for the wife and the brother (family thing going here) they both arrived at the same time and both failed to pick up any signal...
I updated them through wifi then the phone aquired a signal with no problems.But here is the problem, both of that phones will not connect to the cars bluetooth..
everything on all the phones match up from the android version to the baseband so i can't get my head around why there is a problem.?
i hear that its a problem with cm ! but why are some working and others not?
are there any roms that are not cm11 based that i can flash and see if it is the software that's causing the fault or should i wait to see if there are any updates to fix this common problem?
It's the brother's phone thats the problem,he was a long time apple user and i convinced him to change to the opo now thats jumped up and kicked me in the butt...
if this is the wrong place to post this question i do appologise,not used to posting on forums.!
thank you

bluetooth problems
well here is an update if anybody is interested.I installed multirom and mahdi rom,bluetooth connects no problem now

I'm having the exact same issue. I had a Chinese OnePlus that connected easy-breezy to both my BMW and Acura cars. I got a new OnePlus just last week which has not been able to connect/pair at all with either car. The phone can not find any BT devices.
This is back breaking here in the anti-cell phone+driving Northeast.

When they do connect, as mine does, can it send/receive text msg's and emails via the car. Mine works for phone calls and music but no msg's. 2014 Toyota Corolla

same here, just got my OPO not quite a wek ago.
64gig-version, rooted, stock FW, latest OTA.
my BT headset connects just fine, just tried it in the car today, but the phone just does not find the alpine CD-headunit (connected fine with my GNEX or N4 before).
im actually thinking about trying ParanoidAndroid-ROM wich i liked very much on my N4.
any leads?

OK then, I just flashed paranoidAndroid .. Ta-Daa: connects to in-car BT Unit.
ParanoidAndroid by the way doesnt come with the OPO-Lockscreen, but the double-tap to wake up. just enough for me.
cheers!

Weak Bluetooth?

Anybody else experiencing a weak bluetooth connection with the S6? I'm losing the connection with my Garmin Vivosmart in places I've had no problem connecting with other devices. I'm curious about other's experiences on this as a search hasn't turned up much yet.

I have noticed this as well. I could walk pretty far away from my S4 before it would drop. With this S6, I only get a few feet away before audio gives out. Doesn't disconnect, just loses audio.
Also, random loss of audio from time to time, even when the phone is right next to my head.

Yeah I've noticed the same thing with my S6. At work I don't always keep my phone on me and with my M8 I could walk around the whole building without my G Watch disconnecting and with my S6 I can only get a few feet away before the connection drops.

Yes happening with my moto 360 it is annoying and hopefully will be fixed soon

Haven't had any disconnect issues, but for some reason connecting to my car stereo has been a nightmare. It takes like 5 tries before it actually connects.

Same here, takes me 3 or 4 times to try to bluetooth sync with ford sync system. Yesterday it would sync then play for 30 seconds and pause play back. I don't know if its the phone or lollipop as alot of the problems I see are also happening on my nexus 9.

Identical experience. With my S4 and my Nexus 9 I was able to literally get to the edge of my large yard before losing connection with my Vivosmart. Now I can't leave the room since getting my S6. I hope it's software and we can somehow change it, because it's ridiculously bad. I also have had to turn my BT off and back on three times this week because it would crash and refuse to talk to either my Vivosmart or my car. As soon as I toggle the BT on the phone it reconnects to everything. Seems to be triggered by starting my car (i.e. the BT car interface becomes available.) Never had either problem with the S4.

Since so many people are having this problem, it's probably phone related and not just an isolated incident.

Yeah this is one of my only remaining complaints about the device. I can't use my Vivosmart for sleep tracking anymore...it disconnects/reconnects way too many times and the persistent vibes wake me up.
So honest question...let's assume it is fixable by software tweaks. What's the fix in that scenario? Reroute more power to bluetooth radio? Other?

Well I've seen a lot of threads online for other devices where an Android update affected bluetooth range. Obviously there's some sort of software control for this. I'm rooted, and I'm willing to try some things but I don't know where to begin. I'm not an OS / Kernel guy.

i wonder if its what it is connecting to as well as a problem with S6? i have the Motorola Buds headset and it has worked as expected giving me about 100 foot range when talking on it. i also have a 2013 Ram truck with Uconnect and have not had any issues and it connects right away and reads my text etc.. as it was doing with my Note 3 and ATIV.
i havent tried other devices but have a few like a speaker and will see as i use them if i have issues.

Haven't messed with Bluetooth that much on this phone, but I think wifi is a bit weak
Sent from my Verizon Galaxy S6 using XDA Free mobile app

I've had Bluetooth issues. Seems really short range.

Wifi is about the same as my LG G2, but BT is about half as far. I used to be able to get around 15m at work (lots of shelving) but now I'm lucky to get 5m before hearing static and starting to cut out. Sucks because BT is my main source of music at work.

Anybody had better luck after applying the new ota?

I had some issues with mine but i resolved it. I have a 2020 Honda CRV and the first time I set it up everything worked flawlessly. Then a couple months later it wouldnt connect thru the port with the cable. Tried multiple cables nothing happened. Then finally I noticed the Bluetooth wasn't on. Before when I connected to the car port it would always turn bluetooth on automatically and it wasn't doing that anymore. So what I did was turn on bluetooth, reboot the phone and then plug it back in and it worked again. Also make sure you dont have any other phones paired on your car that might be interfering. That happened to me about 3 times when it wouldnt connect and turning on bluetooth rebooting phone then plugging it back in always made it work again.

On my skoda superb 2017 i had problems with AA all the time restarting. charging was ok but i couldnt get google maps navigation on the radio. Then i bought new cable and now it is ok

Tried several tips from all the places, nothing work... S22 plus have the same issues on my car like s22 ultra, but s21 plus is ok...think to stay on s21 plus or so...
From samsung help told me that i must contact google because they ar the producer of app, no way to get an proper answer from google or samsung. Maybe in future updates they solve something.

Does android auto starts and then disconnects? If you have an old pixel phone cable or a thick cable try with that. Also set battery to unrestricted. Do you by any chance have a wireless charger in car and keeping the phone on the wireless pad when trying to use android auto? I have seen issues with aa when I keep the phone on the wireless pad occasionally with my Honda Pilot.

Doesn't connect at all, i dont have wireless charging in car, conection is by cable, messages is "connection failed", calls and media works great.
