Using Bluetooth with hotspot on - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

This might just be asking the phone to do too much, but when I have hotspot on, the phone will constantly disconnect and reconnect with the Bluetooth in my car. I just figured I'd post about it in case anyone has any experience with it tho. Anything that can be done or is it just overloading the phone maybe? I'm running rooted deodexed NK4

i have the same problem as some other people do as well. There's no actual fix, afaik, although the gingerbread roms seemed to have fixed it for me.
You can ask in the appropriate Q&A for your ROM.

in his defense - although I could be wrong, I found that it has nothing to do with one particular rom. I had this problem on stock eclair and many of the custom froyo roms. Once I ran GB, the bluetooth was more reliable.
I'm having the same issue with stock 2.2.
I found a quicker method to fix it.
I downloaded a Bluetooth widget that toggles Bluetooth on and off - this seems to reconnect with my Jeep after the toggle:

I'm sure there are a ton of widgets out there; but, you may want to give that a try!
Thanks,

I also ran into this as after chatting with Samsung support it turns out that the Galaxy line is set to never auto connect to any bt device even if the connection was already there.
I had trouble with disconnections from my car deck (jvc kw-xr810) when it was trying to share contacts. Once I set the phone to deny contact sharing and set up a separate phone book in the deck, it connects perfectly and never drops.
It's not a perfect solution if you want your whole address book access accessible from the car however.

I use tasker for this. I have a task setup that as soon as I turn my car off and BT disconnects, toggle BT off and back on. I noticed that as long as BT is toggled off and back on, it will connect and hold it the next time I use it.
although, I have since turned that task off because GB roms seemed to have fixed the BT issues with my car. I rarely have this problem since switching to gingerbread.
Captivate stock 2.2 intermittent bluetooth problems
I have a stock Captivate with 2.2 android and I'm using a Motorola S10-HD headset to listen to music while I'm at work.
The bluetooth will randomly disconnect causing the music to pause. Sometimes it will reconnect on it's own several seconds later and I am able to continue listening by clicking the play button on the headset. If it doesn't reconnect on it's own then I have to turn off bluetooth on the phone and turn it back on. This will cause it to reconnect but the problem may occur again.
I have switched to listening to music on my Galaxy Tab 10.1 and haven't had any problems so it must be the phone.
Is there anything that will correct the problem?
Is this a defect with my phone or just a design problem with all Captivate phones?

Bluetooth Constantly Drops

This is nothing new to my device, but am just now looking into it. I have it "installed" in my dash and use it to stream media through BT to my car stereo. Unfortunately, the BT on my n7 is very inconsistent. It works fine when connected, but will disconnect quite often. Sometimes it disconnects when I change tracks or when it changes tracks on it's own. Sometimes it disconnects when wi-fi drops. Sometimes it disconnects out of nowhere.
The fix is to turn BT off then back on. Obviously, this is a huge pain. I'm using Tasker to somewhat circumvent the issue although I'm sure I could use it to do more.
Any fixes out there for this? It's not my head unit in the car either. Every other device works flawlessly when connected through BT.

Well 4.2.2 did have issues with Bluetooth, I haven't experienced them in my n4 though.
For ****s and giggles you could try a 4.1.2 rom

Thanks for the reply. I had the issues with 4.1.2 as well...At least whichever version of android it shipped with.

[Q] Bluetooth Auto-Connect with Car Stereo

Has anyone else had trouble getting the Moto X to automatically connect to Car Bluetooth?
My previous phone (Galaxy Nexus) worked fine, and so did my tablet (Nexus 7) when I tested it. The Moto X only connects if I toggle bluetooth off and back on again or if I select CAR MULTIMEDIA from the Bluetooth device list (I have a Subaru Outback). Other phones always connected automatically as soon as I turned the car on.
Does anyone have a fix or a workaround?

Mine is autoconnecting to my Kenwood HU.
Maybe try deleting all previous pairings on BT unit, and then re-pair the Moto X?
As a workaround, you could get an NFC tag and stick it on the dash or somewhere, and program it so when you tap the phone against it, it forces the BT connection.

I did a full reset of the car stereo settings, and I've removed and re-added a number of times. I had been trying to figure out the Trusted Device thing and I only later realized that it only comes up if you have a screen lock other than "slide".
NFC could work, but that's not much easier than just toggling bluetooth. My goal is to have my phone connect even if I don't take it out of my pocket like my old phone did.
I don't know if the issue is specific to Subaru and Moto X or not. My Galaxy Nexus was running 4.4 and worked fine, but I think Moto and AOSP use different Bluetooth.
EDIT: I just tried poking through the options in the car again. It has a setting where you can pick if the connection is initiated by the car or the device, and I switched it. So far it seems to be working!

As it turns out, it *DOESN'T* work. It was a fluke that it appeared to work.
It doesn't matter if it's set to be Car or Device initiated, it does not automatically connect. If I toggle bluetooth or manually initiate a connection from the device end, it will connect and work just fine, however.
Any ideas? Anyone else have a similar experience with the Moto X?
I have a Logitech adaptor in my truck and its behavior is that the phone connects to it fine initially, but when power is removed and restored to the Logitech, it will not reconnect automatically. This is unfortunate as starting most vehicles turns off all accessory power while the starter is cranking.
I have another, cheaper bluetooth receiver that does reconnect, but it does not sound as good as the Logitech (and has ground loop issues).
In my case, the behavior is not limited to the Moto X as I have the same behavior with several Nexus devices as well.

What Android version are you running? If 4.4 - try downgrading to 4.2.2 (I am not responsible if you brick your phone). Google started using new version of Bluetooth stack in 4.4 and it is not compatible with some devices.
I am on 4.2.2 and have zero problem with my car Bluetooth.

It's a DE, so I'm not worried about bricking... But I haven't been on 4.2 for a long time and I'd rather not go back, even to diagnose a bug.
The major Bluetooth stack change (BlueZ to Bluedroid) actually happened in 4.2, so 4.2.2 would have already had it. There have been other changes, though, of course, and I imagine any of them could be responsible for the regression. Glad to know I'm not the only one with the problem, at least.

I think you should be worried about bricking. This is a quote from now deleted thread:
This is a simple chart what can and can't not be downgraded, Thanks to Dray_jr :thumbup:
the only OTA that can downgrade is 4.4 to 4.2.2 Post Cam
here is what we know right now that might make more sense
4.4 to 4.2.2 Pre Cam will Brick
4.2.2 Post Cam to 4.2.2 Pre Cam will Brick.
4.4.2 to to anything will Brick
4.4 to 4.2.2 Post Cam you are ok

Bluetooth won't reconnect automatically

I am rooted but still using the stock ROM. I have two Bluetooth-enabled Pioneer head units and a Bluetooth adapter for my home stereo system with this issue, so I know it's not the other Bluetooth device that's the problem.
When I pair the other Bluetooth device, everything works fine until the Bluetooth device disconnects. I either leave the area with my One, or turn the car off. When I come back home or turn the car on, the One will not reconnect unless I manually turn Bluetooth off and turn it back on again. I don't have to redo the pairing, just cycle Bluetooth off and on. This gets really, really annoying with the car stereos because I have to do it every time I make a stop.
The weird thing is, I had the problem before and it went away when the KitKat update was released. Unfortunately it only worked for a few weeks because I sent my One in for the pink camera issue. I did a hard reset before sending it off and rooted it got back, and now the Bluetooth problem has returned even though it's still on 4.4.2.
Anyone know how to make this go away?
No one is having a similar problem or knows how to fix this?

Anyone having problems with Bluetooth

I previously owned a Sony Z3v and had no complaints. I run and workout regularly so I often use bluetooth headphones while doing so. These in particular http://www.plantronics.com/us/product/backbeat-fit. I'm been having issues since day 1 with these disconnecting. I have to power them down and power them up again to reconnect. Even when they lose connection, they show they are connected but are non responsive. I had not trouble whatsoever with my sony experia.
Anyone else having these kind of issues? I've checked the forums and I don't see any reports. Is this isolated?
I only use Bluetooth when I'm in the shower with the beats pill but it works great for me.

Not entirely related but I have had issues with my original Galaxy Gear disconnecting somewhat frequently when I disconnect my BT head unit or at other seemingly random times that sometimes require me to turn BT off and on again. It's not that huge of an issue usually but BT on my S6 is not perfect for sure.

I am having Bluetooth disconnect issues with my car. Will connect and disconnect repeatedly for about 7 minutes and then stay connected. Very annoying. Have tried several fixes but nothing has worked.
I haven't had an issue with mine when using it for my gopro.
The issue is with Android using Bluetooth 4.0 and WiFi simultaneously. I've had these issues since owning the phone. For whatever reason if you connect your phone to a bluetooth speaker where both devices are BT 4.0, the WiFi will be extremely slow or not work at all.
If you don't believe me, try it. As soon as you connect the device, try to load something like a video or song over WiFi. Or even send a Facebook message. It'll stall. As soon as it stalls, turn off WiFi and it'll magically start working again over cellular data.
No issues here, usually stream to a Bose Color Sound device, getting connection through WiFi
I have issues with mine pretty regularly with my car. A reboot of the phone will sometimes fix it. It's annoying, sometimes it will disconnect from audio but not phone or vice versa. Or it will work perfect, I'll get a phone call and it all goes to crap. The remainder of the drive will generally result in fighting with it. Maybe it will reconnect, but most of the time it won't. Never have I had a phone with so many bluetooth issues.
Had issues with my truck head unit / phone BT. Phone would continually disconnect.
Tracked it down to the Messages transferring to head unit.
If I disabled Messages in the Bluetooth / Allow Access To area, it worked fine, but obviously messages wouldn't go to my truck.
I cleaned all messaging apps, factory reset truck head unit, no fix. eventually factory reset the phone, havn't had any problems since.
