I received a brand new Galaxy Note 4 from Sprint a few months ago to replace a problematic LG G2, but didn't activate it until last week (it sat in it's box prior to that and wasn't even turned on). At first, it worked great, but recently it has been losing Bluetooth and 2.4 GHz (I think) WiFi connectivity every day or so (usually when I wake up in the morning), and the only way to get it back is to restart the phone.
Has anyone heard of this? Or have any suggestions on troubleshooting or resolutions?
Thanks very much!
Three things to mention:
1) I did the tap & go to transfer my data from my old LG G2 (running some version of Android 4.x - I can't remember which one specifically) to my Note 4, but that was a week or so ago and the problems only started in the last few days.
2) The Note 4 came with a version of Android 4.x, but I updated it to Android Lollipop - again, this was done a week or so ago and the device seemed to work with no issues after doing it.
3) I am using the Samsung Gear 2 watch with the phone via Bluetooth but it seems all BT connectivity dies when the above issue happens (such as no ability to connect it to my car BT, etc.)
Thanks for any assistance!
Have you changed the visibility timeout to never? Then keep Wi-Fi on during sleep? For the Bluetooth problem, which I had also,I did a factory reset and haven't had as many problems since.

Thanks for the info. I haven't ever made any of those setting changes previously, which is what leads me to believe something is wrong. For Bluetooth visibility, it is set to "2 minutes", but wouldn't this just be when a device is initially connecting to my phone, and not when a device is already connected? And for WiFi, it is set to "Always" for "Keep Wi-Fi on during sleep", so this is already set per your suggestion. Basically, things used to work fine, and now every night it seems to lose BT and 2.4 GHz WiFi. Per suggestions on another forum, I did a cache partition wipe, but this doesn't seem to have helped. This morning I woke up, and the device had lost it's connection with my 2.4 GHz WiFi network (wasn't even seeing it), and had connected to my 5 GHz WiFi network, and while it still showed connected to my Samsung Gear 2 watch, I don't think BT was working since I tried to connect it to another BT device and it failed. I then restarted, and it worked fine (until tomorrow morning presumably). I'd prefer not to hard reset, especially since there's no guarantee doing so will fix the issue and it won't just re-occur, and because it'll take me a lot of time to back everything up, hard reset, and then restore data, settings, and customizations to my device.
Any other suggestions or thoughts? Thanks!
I just wanted to say that my connectivity timeout is set to two minutes as well. I use my BT everyday for my headset and my head unit in my big truck and have had no issues.

Thanks for the info! This is so frustrating - just started using this device, and already it's broken...lol! Anyone have any other good thoughts or suggestions on what I might be able to do to resolve without a hard reset? Thanks!
Any other thoughts/suggestions? I'm open to Anything at this point!!
I spoke with someone at Sprint Tech Support, and they had me turn off WiFi Power Save Mode using *#0011# (and then choosing WiFi from the three dots menu) to see if this would help resolve the above issues. It didn't, and now even after re-enabling the power save mode, things have gotten worse. Now, every time I leave a location where I'm on WiFi (such as my home), my device's WiFi never refreshes to auto reconnect to other WiFi SSID's elsewhere. So even if I leave my home and arrive at an office where I've previously saved a WiFi connection, the phone stays on 4G/LTE until I manually turn off WiFi and then turn it back on a minute or so later. And I still think the 2.4 GHz issue (above) is happening as well.
WiFi is basically useless on my phone now - anyone have any ideas at all?
Thanks!
I believe I have narrowed it down to the phone as the feature works after I reboot the phone. I noticed this when I got in the car and only the Media Audio led was lit on the receiver. When I go to the bluetooth menu on the phone and select the paired device (car receiver), Phone Audio is unchecked and I cannot re-check it. I have tried deleting the phone from teh car receiver and also the device from the phone and repairing and setting it up. It will connect and cannot select 'Phone Audio'. I also noted that after a reboot, bluetooth feature is turned off and needs to be turned back on. Once I turn it back on and click the gear on the BT device, I can turn on and off the Phone Audio and it will work for a while.
This is an 'all of a sudden' development as I have been running the same firmware and ROM for 9+ months. I am S-off and am running firmware 3.35.401.12 with the ViperOne 4.3 ROM. I have upgraded programs from the play store, but cannot figure out what might be causing this. Can anyone here help me fond a solution?
Thanks!

So just to clarify, you're using BOTH phone and media Bluetooth connections to the one single bluetooth media AND voice enabled head unit in the car?. One receiver?.
Do you have any apps running that will disable things when battery power gets low, like snapdragon battery guru?. Does your rom have any such features built in?.
Make sure both devices bluetooth lists are clear of old devices that no longer have access on resonable terms. Just to make sure its not scanning for another device as a primary.
Make sure you car audio system is running the latest firmware. It can usually be updated via cd/dvd/sdcard.
As mad as it seems, make sure the time is correctly set on both devices.

Yep, yep and yep.
Battery is full , I do not have battery guru installed. I did not change anything. It just now needs to be rebooted before it will connect to BT Phone Audio. Medial Audio connects and works properly, just as it always has.
I have a single Pioneer Premier head unit that I have used for years with multiple phones. If I reboot the phone before it tries to connect, it will connect and Phone Audio works. When it is 'locked out' (my term), I cannot select the block on the that is labeled 'Phone Audio' to check it. As the screenshot shows, it is 'unchecked' and no amount of touching it will check it. The only way to 'check' it is to reboot the phone. Oddly, it reboots with bluetooth turned off and when I turn it on, usually, it is already enabled (Phone Audio).
Thanks for the help,
Keith
After a little research it would appear that, apart from being right about the max enroled devices allowed is 3, "discoverable mode" is required.
Did you connect the phone to the radio or the radio to the phone?. Which discovered which for pairing?. Try pairing the other way from the way you did.
Can you access any options by holding or tapping on any of the fields in the picture above. Something to do with pbap if you can find it and turn it off, most likely under contact sharing. If not, dont worry.
Try turning contact sharing off or see if the stereo will copy them and store them so you can turn that feature off.
Other than that it could just be an incompatibility between the devices. It is not unknown for car audios to be crap hardware.

I am on teh same page of keithspg
I recently resetted my HTC M9 and as coinsequence I have been obligated to reinstall all BT devices (car, 2 headest, laptop)
It worked well (as in the past) for few days but now I have the same issue : I cannot switch on the audio phone !!!
Below the picture:
I could not find any other solution than to wipe the ROM and reinstall. I am now running viper 6.0. no problems. If you are not soff, you may want to ruu it. If you are soff you may want to wipe and install again whichever ROM you are running.

I am also having the exact same issue. I still have not been able to track down which app is the one causing this conflict. I have also done a factory restore and that seems to have worked for a time but the issue started again. It may be unrelated but... Have you changed the themes? I think that's one of the last things I did before it stopped working. Also restarting the phone "fixes" the issue for one connect/disconnect, but after the bluetooth is disconnected it will no longer allow to use phone audio. I have gone into the settings for the "Paired Bluetoth devices" and I am unable to check "Phone audio". It is not grayed out but it doesn't work either. This issue is driving me crazy, I hate to have to restart the phone every time I get in and out of the car just because the bluetooth wont sync. That being said, I have another clue into the issue. Today I was using the bluetooth in the car while on a phone call and transitioned to my Jawbone Icon when I exited the car flawlessly. I turned off the car, turned on Jawbone (so there wouldn't be a conflict of the Jawbone trying to connect to the phone while it was still connected to the car) Immediately the Jawbone connected and I was able to carry on with the conversation. I was really happy about this. However, when I was done with my phone call I turned off the Bluetooth and turned off the Jawbone. About an hour later I received a video through Whatsapp and when I played it there was no volume. When I pressed the volume button on the phone the volume bar had the Bluetooth symbol!!! The Bluetooth had been off for quite a while now and there where no Bluetoth devices present.
Hopefully this gives some insight into this issue that will help resolve it. Thank you very much!
I have also tried the soft reset and the issue persists.

I have recently had this problem on my stock ROM HTC 10. The HTC Australia website online chat actually gave me a solution which worked (!)
Settings > Apps > ... (menu) > Show system > Bluetooth Share > Storage > Clear Data
New findings on my phone.
I have an M9, rooted, unlocked and s-off. It has a stock ROM. I have had this issue for a while now. I don't know when or how it started. Everything used to apparently work fine. Could have been some update or an app I added at some point in time that possibly we all share. I had been restarting the phone as well to get the "phone audio" to work. That became excruciatingly tedious. I did find that, on my phone at least, placing the phone in airplane mode, waiting a moment for that to kick in, then starting up the Bluetooth, brought it up with "phone audio" checked. Then I would just turn airplane mode off.
Still a ridiculous way of getting it to work correctly. However, if this technique works for others as well, then I am thinking that airplane mode is disabling a service or something that is keeping it from connecting correctly. I will be looking into this as I hope some more savvy folks will be as well. If someone does figure it out, please share.

I found another thing that might be causing the issue by reading other forums. I made the adjustment on my phone this morning and I believe it to be working at this time. (For now anyway). I think it might be related to location services accuracy settings. There are a couple of ways to get there. In Bluetooth settings when the Bluetooth is off, you might see a link to it on the initial Bluetooth page. Otherwise, I found them under, Settings/Location. I have my mode set to "Battery Saving". But under the triple dot should be Scanning. Here I turned off Bluetooth scanning and things seem to be doing okay thus far. Just seems like it takes a few seconds longer to connect to my devices. However, so far, no issues. I may be speaking too soon. If I find it didn't work, I will correct myself in another post.

Same problem. Either after using my Fiat Car bluetooth system, or after my BLT bluetooth headset, my Phone audio stops and I have to restart my phone.
On my bluteooth headset I only use the "media" audio.
I am using a Samung galaxy 3 watch also.

Thank you!

Thanks - I believe this has fixed the issue for me!

Late post, but just ran into the same problem with my One M8 with final Viper ROM and my newly installed Pioneer BT head unit. Turning off BT scanning on the M8 worked for me as well.
Bluetooth audio and or media check boxes can't be checked
I was able to resolve the issue on my HTC One M9 by turning WiFi scanning and Bluetooth scanning off, updating the Bluetooth checkboxes for audio and media (both of which were unchecked and wouldn't allow me to check them), and turning the scanning back on.
Has anyone been experiencing their bluetooth turning off on its own since the MNF26U update? I've tried re-flashing the factory image and doing a factory reset, but the problem still exists.
I've had the same persistent issue also as of recently. Only things that use on Bluetooth is my Hauwei Watch and State Farm Drive Safe beacon. I haven't figured out what is causing the issue.

I also use a Huawei watch and the drive safe app. I'm gonna install an older version of the state farm app as it recently was updated now that I think of it.

FWIW: I've had no Bluetooth issues. Only things I use it for are connecting to my two cars for phone, and Android Auto (which uses USB and Bluetooth connection).
I am also experience this same issue. Seems when I get in my car I have to toggle my BT back on. I am using a Samsung Gear S3 with my Pixel XL.

Ever since I got the Gear S3, my Bluetooth will restart every single time I disconnect my Bluetooth headphones. It also never routes calls through my headsets unless I go into Bluetooth settings and uncheck and then recheck the phone audio option of those headphones every time I reconnect them. I've tried maybe 6 different BT headsets and it's the same case with all of them.
I have been having this issue since NMF26U as well. NOF26V actually seems even worse. It doesn't go off immediately upon connection or disconnecting from my car, but then randomly wile the BT lite will disappear while it is disconnected from any devices. Toggling it back on works as does a reboot that comes back on with BT activated even though it was off when rebooting. Hard to believe after this many updates that BT issues continue to be an issue with this phone.
Probably background tasks are getting killed aggressively. Despite being "not battery optimized", my VPN app gets killed too, if I don't touch my phone for too long. E.g. at night. And yes, I'm facing Bluetooth issue too.
Strange, Bluetooth hasn't turned off since my first post. ?

I've had this issue and I'm not on the latest firmware. It's happened twice now. Very random, a week between. Maybe it was an update with the Google app, I've noticed a bunch of updates recently
I am having the same issue. The only thing I use my bluetooth for is my car. I have to turn it back on everyday when I start my commute.
I think I found a work around....

This suddenly started happening to me as well and at first I thought it was my Moto 360 watch going bad since it kept displaying "Bluetooth Services has Stopped". After looking I noticed my Bluetooth was off on my pixel and here is what I did after learning a similar experience from my Camera shutting down on my old Nexus 6.
I went under Settings/Battery/Click the 3 dots in top right corner and select "Battery Optimization"/Then select the little drop down arrow next to "Not Optimized" and select "All Apps"/ Scroll down to "Bluetooth MDI Services" and Bluetooth Share". I selected both of them to "Not be Optimized" but you can play around and select one or the other to see if it works for you. Since I selected both my watch has stayed connected now for about 2 days straight and my Bluetooth stays connected and connects automatically like I've set up to my car and other devices. It also works and stays on when my phone goes into "do not disturb mode" also....
I'm not saying this is the "fix" for it but it seems to be working for me....
I hope this will work for you guys and helps!

Yeah I would be very curious if it works for you as well and hopefully it does. I was getting very frustrated with it but since I changed those settings it seems to be working fine now and I haven't really noticed any difference in battery performance either.... If you don't mind, keep me posted as I'm curious. Thanks!
Had the Bluetooth turn off on my XL before even entering my car (but I didn't see it happen except when I was about to get in the car and noticed no BT indicator). This was approximately an hour after a reboot and no BT devices had been paired though the indicator was on for some period after the reboot. Pretty hard to believe it was an optimization issue since I had run no apps after the reboot. While typing this, the BT icon disappeared again. Add this to getting a Verizon "Server Unreachable" error on my wife's Pixel yesterday and my XL this morning that both needed reboots to remedy. My frustration with this phone is pretty bad today. Both are unlocked BL, rooted with newest SU, running newest TWRP and newest Google version but otherwise stock. P.S. When you see about 4 Google play updates a day for about 2 weeks (with not very many apps installed other than the base) it is hard to guess what my be causing the issue. OK, rant over.
BT has definitely been a PITA since the latest security update. It's completely ruining the music experience on a car I bought days before the update came out. Since the update I constantly have to toggle bluetooth on then off again to get the phone to connect to the car. Then I have to open Google Play Music and start playback manually. This happens several times a day and is very annoying. Had not a single issue before the update.
I am having issues with Bluetooth disconnecting as well. Was bad on previous build but this most recent update, NOF26V build, is worse. I connect to my truck, watch, and speaker system in home and office. Happens randomly without notice. I have tried to test the "do not distrub" theory, after reboot, etc., so far I have not figured out a root cause or time.
Trying the optimized thing for the heck of it. I noticed that only share was listed and not MDI services. I wonder if that is only available on Google phones and not Verizon somehow or only shows if the BT is connected to the device, but I'm not in the car to check.
I too have a gear 3 frontier and since then I have to reconnect my pixels bluetooth, pretty much once everyday. very frustrating lol
Same BT problem
I have been having the same issue with BT switching itself off for about a week now. Never had any BT issues prior to that. Mine is a Verizon Pixel XL. I noticed it when it wouldn't connect to my car, but I quickly discovered that was because BT was off on the phone. I always leave BT on, so I knew something was funky and paid close attention after that. Once I turn it back on it connects to everything just fine and it stays on for the duration of me using it at that time. But when I go to use it the next time, it is off again. It can be a variable length of time in between when I use it, so I don't know how soon it turns off, but it has to be within just a few hours. This pattern suggests to me that something is turning it off, perhaps to save battery, if it goes without being used for a certain time period. I did not knowingly turn on any setting that does that, so it makes sense that an update changed something. I have not tried the workaround/fix mentioned above; I will do it and report back.
Hi guys,
I've updated the phone to the last global beta - 7.12.28 and noticed one big issue and a few other smaller ones. I hope someone might have ideas on how to fix them.
The WiFi turns on as soon as the screen is off. What I've done so far is to make sure no app has permission to turn the WiFi on (using the built in permission manager). I've cleared cache and rebooted the phone several times.
Another issue is the MIUI memory optimization is always disabled, no matter if you change it to something else or not.
And the third one that I can think of right now is the region - it always reverts back to China. Now this has been outgoing for a while, so it might be something with my phone.
What I've done on the phone is to root it and have Xposed install and active. I've also ran Unbloatmi, great script to get rid of apps you don't need. I haven't tried alternative roms like Lineage.
Recently I installed floppy kernel, but the wifi issue remains with the stock kernel too.
I'm open to suggestions
Issue resolved with the next update.
I suggest to you to use global stable. It's old, but global dev is always bugged for this phone. Do what you want, but my experience is bad
Yeah it's always preferred to use stable roms on phones in production environment. But I like to live on the edge And I got into the routine to remove most of the unnecessary apps right after the update. So overall - the phone is quite stable. But now it has the same MAC as my wife's phone. Go figure...
My issue seems to be different from others' as mine isn't just bluetooth losing its connection - it actually unpairs.
In my car (it has an Android Auto compatible infotainment system) it works fine for ages then fails to connect all of a sudden. Then after a while a message pops up on the car's screen saying "bluetooth pairing successful". The phone then asks me for contact sharing permissions. Of course it screws up the smart unlock feature as a result forcing me to set it up again.
On my Huawei watch 2 sport it loses connection and so the wear os app says the watch is disconnected. Bluetooth settings show the watch to be invisible and, as a result, smart unlock gets unconfigured and I have to set it up again. The watch battery discharges very quickly - probably constantly searching for the phone.
I reboot of both devices seems to fix it, for a while.
This is all since the Pie official update.
Does anyone have any fixes please?

No fixes but same problems here
I'm having the same issue also very frequently with WiFi dropping all the time. These two reasons are linked from what I been told. Google telling me to RMA. The pain of that
Mine has done this with my Gear S3 watch since I first got the phone a few months ago, it had me seriously considering returning it for a while. Sometimes it would just disconnect from the bluetooth, but often it would unpair causing me to have to go through the whole set up process again. It did this on Android O, various DP builds of P but so far (touch wood) has been good with the latest version of the Samsung software and Android P.
I'm having the same issues as well and currently searching for answers.
