I have been having what would seem like a hardware issue with my S4, where the bluetooth connection is spotty and drops in and out frequently. It happens on all different bluetooth connections, and i want to say it's hardware bc if i leave the phone alone it is usually better and doesn't toggle in and out, when i pick the phone up and move it around it cuts out much more.
is there any way to fix this? i have no idea how to swap out the bluetooth hardware or if that's basically built into the MB.
thanks for looking

I believe that this also affects other HTC models, but I'm puzzled by it:
If I go to the communications menu and switch off the phone receiver, the GPS also seems to stop receiving. Enabling Bluetooth seems to bring it back to life, but enabling WiFi doesn't.
I don't always want to have the phone receiver working when I'm travelling using GPS, so it's rather annoying.
Does anyone know the reason why this happens ?
Are there perhaps some common parts of the Qualcomm chip that are shared by the GPS and phone and/or bluetooth ?

So I bought this bluetooth headset a pure beauty it self.
(Blackbeat903)
I have found out that my bluetooth signal is not strong at all.
The signal is supposed to reach 3 meters across. but as soon as I put it in my pocket, it begins to loose connection and I miss parts of calls/music.
I tryed to find out waht the problem is, first I thought it was because of programs in the background, that was not it, I even turn the mobile upwards in my pocket cause the transmitter is located in the upper part of the mobile.
But I geuss its just because the bluetooth is not strong enough to transmit trough human tissue? Now I can imagen that more poeple had this problem so is there a program of is there a way to boost my Bluetooth's signal range?
Greets.
It's just the way bluetooth is, you cannot simply change power class of bluetooth unit in HD2.
Well I didn't know about that.
But you can amplify allot of signals or sounds. So I thought it does not hurt to ask around.
Hello!
I have a problem with delayed and cut off notifications over my bluetooth hands free device (Parrot MKi 9200). I can experience it on almost every ROM despite ROMs with Tytung's kernels.
Everytime my copilot live 8 says something like "In 500 meters turn left" it takes a little while (maybe one second) for the phone to establish the bluetooth connection to my handsfree device and all i can hear is "..eters turn left". The only ROMs without this issue are those using Tytyng's kernels. They work just perfect. And yes, I know the workarounds like letting the phone play music all the time, but this doesn't work for me, for i listen a lot to the radio or use the SD Card in my Parrot for playing music - so this is not a solution for me.
I tried to find out more about this issue, but all i could figure out was, that this seems to be an android problem. Due to power saving issues Android would close the A2DP connection and reestablish it, once there is a signal comming up. Please correct me if I am wrong on this one.
However, since Tytung figured out, how to get this thing done right it must be also possible on other kernels and smartphones. Is there a way, maybe to change some settings or a working app or some kind of bluetooth drivers, to solve this issue on other ROMs or even other android phones?
Thank you in advance for your help
Don't know of any app, but just by playing blank.mp3 in music player could help you(it holds bluetooth audio connection-stays on all the time)
your sound cuts are because of low power bluetooth mode, try asking kernel dev to disable it?
I have the same problem and it would be nice to have a buffer application which buffers sounds for Bluetooth for a second and transmit them when the connection is active.
Sure it's an old thread... but has anyone tried this?

Should at least fix the problem for the navigation commands...
Thanks, will try it
OK,
So I'm trying to get some help regarding this issue. I will continue to try different ROM's and what not to see if it can be resolved. I'm simply at a loss to where the issue lies though, however as of today, every custom ROM has been giving me trouble. My plan for today is to flash a stock ROM via Odin and then if that works go for Imperium, however I'm hoping with your help I may be able to solve it on something like CM12 or what not because I prefer the flexibility of a proper custom ROM.
OK, so the issue I have:
I have a car head unit which has bluetooth built-in. Music plays fine through Bluetooth, no jitters or issues. However, when I try and call someone and I'm listening to the radio or something non-Bluetooth, the phone does not send the signal (?) to the head unit to switch to Bluetooth. This means the call will be made via the dialer app and while the audio IS being routed through the bluetooth channel, the head unit does not know about it because it hasn't received the signal to switch to Bluetooth. I can switch it manually to Bluetooth and make and receive calls, but this isn't convenient at all and probably quite dangerous when I'm driving a car. The same applies when receiving a call.
Here's the thing, if I go into Bluetooth, select CAR KIT and go configuration, if I disable Media Audio, then it works fine! The phone correctly sends the signal to switch to Bluetooth and the head unit does so. The call goes through and it all works fine. This is repeatable.
Therefore, the issue I'm having lies in the fact both Media and Phone Audio are enabled at the same time. Has anyone else had this issue and does anyone have a suggestion to fix it?
Before someone suggests "just disable media audio". My answer is no, this isn't convenient at all. I use Bluetooth media quite a lot, and simply disabling and re-enabling it everytime simply isn't an option.
So far, I've had this issue on:
CM12.1 Optimized
CM12.1 Nightly
Mokee ROM
DirtyUnicorns
CM12 Nightly
I'm yet to try a stock Lollipop ROM. I know for a fact however, that stock KitKat DOES work.
I really could do with some help here, so any suggestions would be awesome.
all the roms you have tried are aosp....aosp is not designed for the s4 as its not an officially supported device (its not a nexus) so things like bluetooth and the camera will always be broken as the required stuff needed is proprietary to samsung
go back to stock and your problem will be solved

The Bluetooth itself is fine. Audio quality is fine. Call quality is fine. It just seems like a tiny little thing that's causing all these issues for me, because if it could trigger my car head unit to switch, I wouldn't even dream of stock. Also the camera seems fine to be fair?
I'm not keen on going back to stock.... at all, so I'm thinking Imperium. It's a shame though because apart from this BT issue, CM12 is fantastic on this device. Takes a 2 year old phone and makes it feel like a brand new phone.
I really hope someone can fix that Bluetooth bug in CM12.1. I may even look myself, it must be something pretty small from a coding perspective because as I said, the functionality is clearly there as evidenced by the fact it works with Media audio turned off.
Regardless, thanks anyway
Changing the modem did not solve my problem.
When did you try the Optimized and the nightlies? There have been a lot of fixes lately regarding bluetooth.
I got a new MOTO 4G Play to replace and older Samsung. I like it except for one thing. I have to unpair ("forget") the device and then cycle the radio on and off a couple times and then turn on the adapter and then pair and connect to get it to work. I have to do this each time.
I've contacted that adapter mfg and moto they both point to each other. They even said a new pone won't likely fix the problem. No one is actually interested in solving the problem. I'm sure there are plenty of others in the same situation. The adapter mfg says it is a problem with moto phones.
Are there any bluetooth radio hacks or other versions. I don't know what radio I have or how to find out. I'd rather not go with a complete custom ROM at this time.
Any suggestions on what the problem could be, how to fix, how to address compatibility problems when both mfgs say the other is causing the problem. Is there somewhere to officially complain about BT compatibility issues? Is BT an industry standard or a specific company that licenses it?
It seems like I should have some recourse here, but, so far I've spent a lot of time going in circles dealing with level 1 support people who only fill in forms or read off lists as well as time and money spent on phone calls, being put on hold, etc.
While Bluetooth is an industry standard, there are different versions (3.0, 4.0, 4.1, etc.) which transmit data in different ways. There are other standards as well, such as A2DP. But for all of this to work, both devices need to be able to detect each others' Bluetooth MAC and store it long term. If one device forgets it has that knowledge, then it won't recognize the others' BTMAC at all.
Changing to a ROM isn't going to fix this (Lineage is notorious for killing BT when you change from cellular to WiFi, and to this day it still isn't completely fixed). What I recommend is going into Apps, looking for Bluetooth Share, and clearing its data. Then try re-pairing to the device.
I tried clearing the data as you suggested as well as during a hard reset and that doesn't work.
I do have a sequence of steps that works pretty consistently, but, I have to do it interactively. I'm wondering if I could just write a script to do these steps. Some of them like the pairing and the connection take a little time and may need some timing steps. Ideally it could access a signal when the connection is made or not made etc. I could just set it in motion and go about putting on the seatbelt, starting the car, etc while it is working.
I have no idea what commands the different things I interact with use. It involves forgetting the connection, cycling airplane mode on and off, pairing and then after they are paired connecting. Any ideas?
Some people on the Moto forums suggest disabling Bluetooth Scanning. It seems to work for some people; others report no change in their connection after turning it off.
I'm running LineageOS, and as the previous reply stated, my Bluetooth restarts when changing between WiFi and cell data. I tried Bluetooth scanning on and off, and neither seemed to fix the Bluetooth restarts.
