Stock B29 A2017U forgets Bluetooth devices - ZTE Axon 7 Questions & Answers

I've had my phone for about 3 weeks, and twice it has just forgotten my paired Bluetooth devices. The first time, it happened while it was connected to the device. I heard the disconnect message on the headset, and I thought that the phone had just rebooted, but there was no reconnect. When I looked at the phone, the headset was gone from the paired list. The second time was today, when I turned on my car speakerphone. It went into pairing mode, and sure enough, my device list was empty. I had just used the headset a couple days ago.
Is this a know issue?

Bluetooth woes

Thought I'd fire off a thread to see if anyone else was having issues with BT on their x10's, this stems from an issue I was tracking originally shown by the Wiimote controller app (http://forum.xda-developers.com/showthread.php?t=672884 from about page 21 onwards) where by bluetooth on the phone and effectively the controller would lock up and both would need resetting before they would work again (turning off the bluetooth on the phone would work but then not allow it to be switched back on again untill the phone was rebooted).
I then also tested the BT by trying to do a large file transfer (700mb) via BT from my laptop which was unsuccessful even after several attempts I was never able to get past about 5% (small files <10mb seemed to be ok as I've transfered photos etc accross with out issues), this however didnt result in a complete lockup of the BT it just stopped transfering after a while and would eventually time out (although i did have to unpair and reset both on one occation as the laptop started to fail transfers imediatly before even actually trying to send).
Has anyone seen similar?
Yes, I have had some BT issues, just like you I had BT crash and had to restart the phone to be able to start BT again.
If I remember right, I was just connecting my MW600 headset to the phone, and already had my macbook associated to the headset.
Playing around trying to make the headset work somehow crashed BT (forcing a restart of the phone)
And another problem i´ve had is that sometimes you are unable to reconnect the headset and having to restart BT in the phone to make it work again.
BT also crashed once when I had it connected to my car, in the middle of a conversation, again forced to restart the phone to be able to start BT.
Yeah, there are some issues to iron out...

[Q] Bluetooth Pairing issues

My issue today is that my bluetooth will not pair properly and remember its configurations. My initial pairing on my phone with my car's flexsmart X3 works perfect, however when I turn off my bluetooth on the phone or turn off my car and turn it back on the phone will still see the flexsmart and it will say it is paired but I get no sound. Upon further investigating I find that in the options setting that neither the call nor music tick box is checked. If I try to tick them it will think for a few seconds and then gray out and do nothing again.
I never had a problem with my note 2 or my temp replacement evo 3d remembering these settings. All I would do with those phones was pair it once and then any time I hopped in the car I would just turn onm,y phone's bluetooth and go. Now with my note 4 I have to unpair and repair the devices each and every time which is a huge pain. Once I have initially paired the bluetooth though it will stay connected without any interruptions. Also pairing for me is really fast and only takes a minute or so. My problem is that again instead of my phone remembering the current device settings that it is paired with, it will forget to associate it with calls and data after I turn the bluetooth off and then later back on even though the phone will still remember it is paired with the car bluetooth.
I have read a little bit that this is due to samsung note 4 using a newer bluetooth standard than its predecessors. Is there anyway to circumvent this issue by maybe rolling back the bluetooth drivers or something? I even thought about creating a tasker profile to help with this but still I would have to physically press the search button on the flexsmart eachtime.
First world problems I know but it gets a tad annoying having to unpair and repair my phone each and everytime I hop in my car to go somewhere if I want to listen to my music. Any and all suggestions would be great.
Also right now I am on a sprint network rooted stock 5.0.1 if that helps any

XT1572 Bluetooth: Phone audio won't turn on without reboot (after updates/recharge?)

Hi all
I'm having this strange (but really frustrating) Bluetooth bug on my Motorola Moto X Style (XT1572) with Android 6.0. I already tried restoring the Phone to factory settings and without any extra apps but the issue persists. It just suddenly started happening (about a month ago).
Nothing has changed in the bluetooth devices that I use with my Phone. I connect my car using Bluetooth and if I'm not in my car, I use a Bluetooth hands free kit to make and receive my Phone calls.
About a month ago my bluetooth started acting weird. When I'm in my car and want to make a Phone call, it starts the call on my Phone but then my car says that something went wrong and the call couldn't be initiated, although the call is continued on my phone. I do receive my text messages on my car and can also sent them but I'm unable to make/receive Phone calls.
When I receive Phone calls, they don't come up on my cars media. However, my Phone says its using Bluetooth for the call and the bluetooth connection is up. When I'm having this issue, I can not disconnect the Bluetooth connection with my car on my phone. It refuses to disconnect and I can not switch to any other Bluetooth device. The same goes when I'm having the issue while connected to my other Bluetooth hands free kit. In the advanced bluetooth settings of the bluetooth connection on my Phone, I also noticed that when the issue occurs all Bluetooth functionality is checked (eg. 'Media audio'), except 'Phone audio'. 'Phone audio' is not checked and it refuses to check it (however it's not greyed out). When I tap on 'Phone audio' in order to enable it, you see it getting checked for like a few microseconds and then it instantly gets unchecked again.
The only remedy I found is to power off and start my Phone again. Very frustrating if you want to make a quick Phone call and that you have to wait 5 minutes each time or if someone is trying to reach you but they can't hear you and they keep calling back while you try to press the power off button and drive your car . Why do I even have Bluetooth .
I've noticed that when I keep my Phone powered on at night and let it charge, the issue is present. If I recharge my Phone while it's powered of, pull out the power plug and then power on the Phone, there is no issue.
It seems to me that it has something to do with the update process...
Any idea how I can solve this issue?
Previously I did had other bluetooth issues like sudden switches between the phone's speaker and the bluetooth hands free (without any clear reason), it would just switch the bluetooth audio off and on again. So imagine, I'm calling someone with my hands free kit and suddenly the sound is gone. I grab my Phone and hear the other person talking, I continue the conversation using my phone's sound, then the sound is gone again and I need to continue with my handsfree. Other times when the phone said it was using bluetooth audio, it actually wasn't and I had to select 'Phone speaker' and then bluetooth audio again to get audio via bluetooth.
I don't think it has got anything to do with my car's bluetooth or my handsfree because the handsfree works flawlessly with my laptop and the car's bluetooth also works perfect with my partners Phone.
I have the same problem as you and i've never found a solution someone could help us please
Anyone?

So basically since the December security update that was released in February? Yeah, we know... some people seems to have issues with Bluetooth since then, but some people don't, not sure exactly why. In the Lenovo support forums there is even some mention of Bluetooth issues (although they come short of admitting there is a problem) on the latest update.
If a factory reset doesn't cure it, then you just have to wait... we don't have the factory firmware images for the latest release to reflash and downgrading is a questionable solution at best. Hopefully the factory images become available or the Nougat update actually gets released and one of those fixes it.
Sorry, that's the best I have for you... which is basically nothing.

Bluetooth turning off

I got my PH-1 in the Sprint Lease deal. (What a deal for a high end phone!) I'm generally enjoying it, but for some reason Bluetooth gets turned off all the time. I have BT trackers and a smartwatch (Gear Fit 2), so that's quite annoying. Anyone else have this issue? I've googled around, but haven't found anything.
1) Have you tried to keep Bluetooth on, but no devices connected?
2) Try keeping Bluetooth on, but only one of the devices connected.
3) Do the same as #2, but connect the other device.
Basically just try to see which device(if it is the problem) might be causing Bluetooth in your phone to turn off. I don't have smartwatch connected to my phone, but I do use couple of Bluetooth headsets and they work fine and I haven't experienced Bluetooth disconnects.
that is odd, I have not had that happen
You are not alone. Mine is doing this too. At first I thought I was hitting the quick toggle but it isn't even there to accidentally hit. I only pair my Acura stereo and Jabra Elite Sport headphones to it, nothing else. But I used both those devices with my 6P and had no issues. I'm going to post about it in their subreddit, they seem quite active there.
I also have this problem. For no apparent reason, my bluetooth would be off maybe a few times a week. Maybe once a month, I would lose pairing to all my bluetooth devices and had to re-pair them all.

Call gets randomly transferred to the phone when using Bluetooth

Hi,
Problem is related to calls when using any bluetooth device (tried it with Plantronics, Sony, Bose, and head unit of the car, so the problem is phone related).
It is something new, as I have the phone for 3.5 years and initially everything worked OK.
Phone is stock, non rooted.
Absolutely no problems with listening to the music, only with phone calls.
Scenario:
Incoming or outgoing call works OK through bluetooth device for some time, then, randomly, audio switches to the phone itself. On the display you can still see that audio is routed through bluetooth, and if you select phone, and then reselect bluetooth device, audio gets restored for some random time period, then will be transferred back to the phone. Can happen several time on one call. Average time before transfer is over 30 seconds, but sometime it works for much longer.
All this time phone still considers bluetooth device connected, and device thinks it is connected to the phone.
Tried to switch off WiFi calling, VolTE, Bluetooth device scanning, removed some "phone-related" apps - but the problem is still there.
Any ideas before hard-resetting the phone ?
Hi,
I have this same exact problem! I hope someone has some advice
