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.

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.

I'm having issues with my car bluetooth too. It works fine initially, but every couple of days I have to delete my phone and re-pair it for it to connect again.

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.

I'm getting sent a new one since I've been having these problems

I had Bluetooth issues on an old phone, and when I flashed different roms the issues were fixed. This leads me to believe that it's software related

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

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?

Choppy Bluetooth?

Just wondering if anyone else is having issues with their bluetooth? Mine seems to be ok for a while then starts cutting in and out to the point I can't listen anymore. Seems to happen every time I use it and with three different radios. I plan on visiting the Sprint repair shop but wondered if I was missing something?

Having the same issue, I've already tried deleting the bluetooth cache, un-pairing/re-pairing and even went as far as to boot into recover and delete the entire cache.
Nothing seems to fix the issue, still cutting out like a champ. Starting to consider going back to the note 4.

Same problem here when I connect to my cars bluetooth radio. Also the network connections seem to be all over the place as well..

Give them time, they had some similar problems with the S6 Edge and got them fixed relatively quick.

Yeah I can hold the phone a certain and replicate it often ... Usually blocking the bottom right antenna spot

Same problem here. I've had similar issue with the Note 5 but it wasn't as bad as on the Note 7.

My Bluetooth reception is a lot better on my 7 than note 4.. I haven't had any choppy or cut off music with my bluebuds x. On my note 4 i would get it all the time

Mine has been VERY choppy. To the point that I dont even bother with Spotify in my vehicles anymore. And thats my main source of music!

Ditto. Ford sync system in my 2015 super duty. I thought it was my trucks problem. Par9ked my wifes s5 and no issues. Pandora is my main source.

0 problems here, pairing 4 different types of headsets, 3 vehicles and even my computer and gear watch streaming the sound through either. I mainly use pandora and sometimes just the music app or youtube. My data is what seems to be very touchy on this phone, where on my n5 I still get more bars than the n7 in the same areas.

I have the same problem, so does my wife's Note 7.

I had the same problem then I went into the settings for advanced location services and turned off random bluetooth scanning and wifi scanning. Now it works perfectly.

Gonna see if that helps thanks!

I have no issues with Bluetooth whether it's in my car, through my wireless headphones or using my Gear 2. I'm loving this phone. The bluetooth connection is actually better on this phone than my Note 5.

Also...Nearby device scanning. I shut that off as well and it has helped. Still, I'm getting occasional dropouts, but it's tolerable.

Yeah, i can replicate by doing this as well... and unfortunately i use my right hand to hold my phone and it covers that spot sometimes.

I agree with you. It's better than having those 2 settings activated. It still sometimes has its hiccups but not as bad.

Agreed. I'm still having far too many dropouts/interruptions/skips/pauses etc.... to call it a final release. I listened to music that was on my device and still experienced the dropouts/interruptions/skips/pauses. Has anyone else experienced Pandora speeding up toward the end of a song?? Almost like the song is sped up to compensate for the delays/interruptions??

Meh...

No chop here, just got my N7 today. Tested on Klipch R10B, KMC3, Groove, UE megaboom, Lexus Infotainment and Harmon Kardon Aura, Braven BRVX

Phone drops call, will not dial out until rebooted

Two times this has happened to me. I will be talking and about 3-5 minuets into the conversation my side goes dead, I can not hear them, but it shows as connected to call. I hang up, try to redial, but it will not actually dial out, just sits on the dialing screen. After I turn it off and back on it works.
Anyone experience this, or heard of it? AT&T Variant.

I've experienced something very similar; as with you, it randomly happens after a couple of minutes of conversation. I have also noticed once this happens all audio on the device is muted (will play tracks in the music player or video but no sound). once restarted all is well again. Does this happen on your device?
Furthermore, I have experienced the device restarting on a couple of occasions mind call. unsure if this is related or not?
international Dual sim variant

I experienced the same after setting network to 4G only. Switched back to auto and havent had this problem so far again.
The other side of the line hears lots of noise when this happened to me. I did call my own number the second after and got the same.
Fingers crossed this was the thing for me..

same for me....after call drops no audio at all...
only reboot fix the problem
it happened at least 4-5 times
i noticed that this problem occures whithin low signal area.

It happened to me yesterday after I got in the underground parking from our office. I tried to call someone from my car after I got out and it showed the message "Call failed". Strange that my former iPhone 7 Plus had the same issue. I am on Vodafone Romania.

i am experiencing the same issue. Every 2-3 days my S8+ mutes it self while on call and i have to restart. I am on Cytamobile-Vodafone Cyprus.
I removed my SD card, changed signal from Auto,2G-3G and 2G with no difference.
This only happens while on call and maybe on low area singals (cannot be 100% sure).
Seems like a software issue but Samsung has not said anything regarding this issue yet.

Try to install the 'Soundabout' app.. With no further settings, Just install it. Its something like all sound to be diverted to another output source... 4 days with this app, no symptoms

I can confirm that Soundabout doesn't solve this issue..... The problem always shows up in my office, where i have a very low signal spot.
It happens about two times per week and always needs to perform a reboot in order for the sound to work again

its realy annoying

Has anyone tried resetting the phone to factory defaults? Let us know please

I did first: factory reset, same problem.
Second: on support they replaced microphone, same problem.
Third: replaced board, same problem after few hours.
Problem is always the same: I can hear them but they can't hear me. If call back again everything is ok and working.

i think its factory fault they changed whole motherboard and the problem still happening most times, i have 2 phones same problem and signal full bar on both sim, waiting Samsung answer

My S8+ drops calls like crazy... What an expensive piece of crap.

There have been reports of Samsung's fps software causing unrelated modules to periodically stop working until reboot (modules such as iris scanner or WiFi internet connection).
As an experiment, try turning off Fingerprint Gestures and all fingerprint security functions in Settings, as well as deleting all registered fingerprints. Then reboot and see if the call-dropping problem goes away.

Spoke with some people today and seems that in Cyprus all of the users that reported this issue are with Cytamobile/Vodafone. Noone of the MTN and Primetel users are reporting related issues.
Seems that the issue is with Vodafone?? I noticed that in most of my calls the sound is clearing like switching to HD Voice so maybe this has something to do with it? With MTN and Galaxy S7 Edge i did not have that.

Hi,
Since my phone got updated to G955FXXU1AQF7 the issue seems to be resolved. I have been using the phone for 5 days now without any issues whatsoever. i will update if anything changes.

Battery, Storage, Pairing, App Problems etc...

Ok, given an S3 Frontier as a gift. Was fun to fiddle with. The previous owner had no issues. I immediately paired, updated etc.
I've had so many problems. Some Days the watch lasts for 2-3 days, but 95% of the time it'll be dead within anywhere from 5 to 8 or 9 hours. I've turned off all tracking, and Hr settings etc, tried battery saving mode and to no avail, I cannot sort out the battery drain problem. Updates and resets. Nothing works.
I have also noticed the storage on the watch fills itself up even though I don't install anything on the device at all. I've also noticed on some occasions after I've reset the watch to try and fix my battery drain, that the galaxy watch up won't even pair with the device and I'll end up having to uninstall and reinstall the app on my phone to do it again.
I've noticed the watch pairs with my phone fine but once the storage mysteriously fills up I find that trying to use the app with the watch in any way is pointless.
I've gone through threads upon threads on official forums and here etc and I still can't figure it out.
I've sent through a service request, I've told them I don't have proof of purchase due to it being a gift. I'll see how I go?
