Bluetooth connectivity_auto connect - Huawei Mate 20 Pro Questions & Answers

When I bought this device in October, and once connected to my car it automatically connects to my car from the next time onwards whenever I enable the bluetooth on my phone. It automatically detects my car audio as trusted device.
Till date I have received two updates, the bluetooth after enabling in my device while in my car would not connect automatically. I had to go into settings>bluetooth>view my paired devices>then select my car audio and then it connects.
Do you think this is a bug or I am missing something here? I am still on ...171 firmware.
thanks

There are several things you can try. The easiest is to forget the connection in the M20P Bluetooth menu and then pair your phone again. If that doesn't work you can go into settings/applications. You will need to select the three dot menu then show system processes. Find the two Bluetooth processes and clear the cache and data for both then try repairing your phone with your car. If that doesn't work either you can boot into recovery (I don't remember if you press volume + or - while also holding the power button down but it's one of the two). When you are in recovery select wipe system cache and then reboot your phone.
Wiping the system cache fixed Bluetooth issues I was having a couple times and it doesn't erase your apps and files like a factory reset. Wiping the system cache can also help when you notice wonky phone behavior after an OTA update.

This issue keeps occurring randomly. guess it will be fixed sometime in the future by any new software updates.

[Q] How do I get Bluetooth to connect automatically?

Running ICScrewed 2.0.1 and I've been running into a problem over the last few roms I've flashed where my Bluetooth doesn't auto connect.
I have a Jabra Cruzer 2 bluetooth speaker in my car that I've paired with my phone. Tasker is setup to start a menu system when the bluetooth connection is established....but it never happens. I have to go into the BT menu and press on the Jabra device to make it connect. By default it shows "Paired" so I press it and it changes to "Connected".
I know when I had UnNamed previously it was auto connecting everytime I would jump in my car and hit the connect button on the Jabra. It hasn't worked that way since I've gone away from UnNamed. I even tried going back to it and now it doesn't work.
I've checked the Jabra and there's nothing to the settings so I'm 99% sure it has nothing to do with the device.
Does anyone know of a place to tell it auto connect when detected?
Followup question,
I also can't get phone calls to go over the bluetooth device either. Is there special place to look to make sure calls go over bluetooth by default?
Thanks everyone for your responses.
You may have to re pair the device. Did you restore bt pairings when you changed ROMs? That can cause no end to problems, especially when they are different bases.
I have the same Jabra and it connects every time I press the talk/end button on the unit.

I may have somewhere along the line Titaniumed the BT pairing back. But my most recent flash of ICScrewed was preceded by wiping dalvick, clear cache partition, and wipe before installing full. So I'm not sure how anything would have come over unless there was a folder somewhere with bad data.
Is there a folder I should clear out and pair from scratch?

KIW-L24.. bluetooth calling not working anymore

my Bluetooth headset is connected and music is working fine..but bluetooth calling suddenly stopped working after few days. whenever i'm calling with my headset i and the other person can't hear anything. i checked settings and phone audio is turned on. please help.. thanks
Got same problem
Few days ago earphone stop working. On other phone work's fine.
On my KIW-L21 I can start and stop calling. While I'm calling can hear only noise.
I had the same problem. Huawei support was no help. But I finally wiped my cache partition and that fixed the problem. No need for a factory reset.
1) Turn off your phone, wait a few seconds
2) Hold volume up button and power button until your phone starts
3) select "wipe cache partition", wait for it to complete
4) select "reboot system now"
Aee tou facing the issue on stock or any custom rom?
I had this issue on the stock Marshmallow ROM. I would have to do a restart, then unpair and repair the Bluetooth headset in order to continue making calls with it. It would fail to the point I had to follow this procedure about once per day. Making sure I did a restart before starting my day made it occur much less often. If I didn't restart every 24 hours, the Bluetooth would stop working pretty quickly on the 2nd day.
I have since changed over to LineageOS 14.1 and am now running Nougat 7.1.2. Haven't had the issue return since.
On another note, my Bluetooth mouse also works now, which never worked before. Definitely a better Bluetooth experience. The Bluetooth on the stock ROM from Huawei is just a disaster, plain and simple.

Network Issues after Nougat Update

Has anyone had this and fixed it, or do you know how? I have a Swift2Plus.
Since the Nougat update I have random disconnects from WiFI (gets turned off) Bluetooth (gets turned off) and phone (SIM taken out of service). It makes my phone pretty useless as it's a pain repairing all of these and I miss calls and messages. Also Bluetooth is always showing in settings as disconnected, even when it's turned on and working.
So far I've tried a network reset and deleting the system cache but nothing changes.

I'm also having Network issues, my Hotspot turns itself off at least 3 times in a row before staying on, and I get a lot of 3g connection indicators, my network hasn't changed and I'm in a strong 4g area . . eventually the phone settles on 4g . . I'll also point out the pointless duplication in the UI, previously the pulldown menu was a straightforward tap and select for Bluetooth etc . . now it takes you to a second screen where you can turn Bluetooth on/off . . total waste of time and poor interface design.
I've no problems with wifi and bluetooth, but there is an OTA update fixing these issues (see WileyFox facebook). So wait a few days for the update...

Wileyfox suggestion of clearing the system cache seems to have fixed the random disconnects, so you could try that. On my phone there didn't seem to be any issues created by doing that.
They did say in reply that the issue of Bluetooth being permanently shown in settings as disconnected (even though it's on and working fine) was a known problem they were working on.
That tallies with the helpful post below from rivierakid saying a Wileyfox fix was in the works.

BTW here are the instructions for clearing the system cache, courtesy of Amy at Wileyfox-
"If you are using a model previous to the Swift 2 series, please try the following.
"Wipe cache partition"
To do this, please turn off your Handset.
Press and hold down the Power and Volume down button together until a menu appears.
Select "Factory reset", "Wipe cache partition" and then "Yes".
this should not take long, now go back and select "Reboot system now".
Please monitor your handset over a few days to see if this has resolved your issue.
If you are using the Swift 2 series, please try the following.
"Wipe cache partition"
To do this, please turn off your Handset.
Press and hold down the Power and Volume up button together until a menu appears.
Press the volume down button until you see "Recovery mode", your Handset will restart and enter another menu Select "Factory reset", "Wipe cache partition" and then "Yes".
this should not take long, now go back and select "Reboot system now"."
I didn't understand the reference to factory reset and just used "Wipe cache partition", which seemed to do the job.
Good luck!

XZ1 and bluetooth

How is bluetooth doing?
I preordered it a couple of weeks ago but I am a little bit worried about. I still can withdraw the order.
I have Sony's SBH54, Bose QC35 and a Peugeot 2008 car stereo, just to explain the case.
Thanks for the help.

Has anyone said there is issues with Bluetooth? I don't have Bluetooth in my car anymore but I had issues sending some files
Sent from my Sony Xperia XZ1 using XDA Labs
It has been reported by one fellow on the Sony's forum but he was the only one. He talked about car stereo on a bmw x1.
Curiously, symptoms was similar to the nexus' oreo Bluetooth problem.
I suggested him to get in touch with the car dealer but when I found the nexus thread I became a little bit worried: I have to drive a lot for commuting and I need noise cancellation at work, hence car stereo and qc35.
I had a Z5 and recently bought the XZ1. I use bluetooth on my car stereo on a daily basis and never had issues with the Z5.
The XZ1 however, is a hit and miss. It would connect fine but sometimes it either won't display media information or I won't be able to use media controls on my car stereo. Most of the time it would work just fine.
A solution which worked has been setting AVCRP to version 1.4 by developer options under the Bluetooth section.
QC35 are still to be tested because they've been sent to service, but car stereo and Sony SBH54 are fine.
I've already reported the solution to Sony's tech support.
XZ1 compact here.
No problems with my QC35, also no problem with my old car's bluetooth handsfree system (2005).

Old things used to be built better.
Thanks for the QC35 check.
I have noticed delays connecting initially to devices but fine after. I have noticed connection issues though with the new "near bluetooth" protocol. I can't connect to a Roomba Braava Jet at all.
Just found this, trying to test as we speak.

I have no problems using my xz1 with my srs-x11 and my peugeot 208 Bluetooth system. Mine works fine
XZ1 Compact Bluetooth complete failure
I have issues with all Bluetooth devices I regularly used with my previous phone. That includes a few portable bluetooth speakers like Ion Plunge or Philips PixelPop (connects but music does not play, hit or miss, had to forget and reconnect the devices manually almost every time), 3 different brand car bluetooth handsfrees including Volkswagen Go! bluetooth system, Opel Vauxhall integrated bluetooth, Renault Traffic integrated bluetooth. On car bluetooth either information is not displayed on the screen or device cannot be controlled from the car controls, sometimes when autoconnected to Volkswagen Go I see mute sign on the screen when my phone is not muted and music supposed to be playing. So much frustration considering that I got used to not having any issues with my old iPhone that I personally hated for many other reasons.
In case you guys haven't seen yet, there's various fixes coming with android's november update that should address most, if not all of those issues.
EDIT: I stand corrected, the mentioned updates are for the Nexus/Pixel devices, though I'm sure they'll be integrated into the Xperia device's software as well eventually.
I don't know where to put this, but this is the first thread that shows up on Google so I'll put it here.
I have had nothing but issues pairing my phone to the radio on my Hyundai Elantra. The headunit would report that it pairs successfully, but my XZ1 compact would never actually connect. Eventually "ELANTRA" would appear in my phone and the only Bluetooth feature available is Contact Sharing.
A few weeks ago some random method of me pairing and unpairing got it to work and I left it alone. I recently had to wipe my phone and start over, so I had to figure out how to pair this stupid thing again. I took note of what I did so I could share for others (and for myself when I have to wipe my phone in the future).
Delete all stored devices on your phone and headunit, and then go through the pairing process again. At the moment you successfully type in the Bluetooth pin code and hit pair, kill the power to the headunit. In my case, the radio lady was in the middle of saying "pairing complete" when I turned the key off.
The phone should switch from "Pairing" to "connecting", at which point you can turn the key back on. It should finish pairing and connect.
Hopefully this helps someone
I have a plantronics BT headset paired to my XZ1 compact and it kept disconnecting and reconnecting the next second. Sometimes the BT would show that is is connected but when i make a call, it isn't connected to the BT headset. I emailed support and follow their instructions below and still have the same problem, anybody experiencing the same? Hope there is a solution to fix this problem soon.

Like the others I also have problem with the Bluetooth after updating to Android 9 on my XZ1.
The problem is on my car Head unit, I can play song thorugh Bluetooth without any problems but when I receive a phone call or make a call although Bluetooth is still turned on but the voice come from the phone and sometimes it switches between the head unit and the phone repeatedly so I have to turn the Bluetooth off and answer the phone. About Bluetooth Avrcp which is on 1.6, some said if you put it on 1.4 might fix the problem but it didn't. And I also checked the avrcp For Android 8 is also on 1.6 and I never had such problems on Android 8. This all happened after updating to 9.
It's been months I'm searching for a solutions and I'd be grateful if someone could help.

Question P6 Bluetooth Problems

My p6 will see most some of my Bluetooth devices (laptop, tablet, TV, earbuds) . It pairs with the earbuds, but everything else it will try and pair, usually does not. If and when hen it does pair, that pairing is dropped dropped within 5 secs. Cleared BT cache, rebooted. No joy. It will show no paired devices.
Network reset.
Clear system cache.
Hard reboot.
Do not factory reset; find to root cause as it will likely reoccur otherwise, eventually.
It may be a 3rd party app, try in safe mode.
Try rolling back associated apks to their factory load versions if updated.
Double check permissions and settings.

You play with bt settings in Developer options?
Is power management active? This doesn't fit power management's profile for erratic behavior but maybe it got "smarter".
Played with BT in developer. I will give power a try, but I don't understand why the buds and car are seemingly 0k. I haven't the chance to be in the car for an extended period.

Think about the clues.
Are the other devices configured properly?
Check Event Viewer in Windows for error messages, it might tell you why this is happening.
Try some Google searches for similar issues, it can be other devices and OS versions. Many issues span both. With a newer device this strategy works many times.
To see if power management is active Developer options>standby apps, all buckets should show as active, otherwise power management is running. It can't be disabled here though.
Power checks out. I tried to send a file from the tablet. Phone showed the attachment, file failed. Was able to send a file to tablet using "nearby device"

Do it to the PC and see what error messages Event Viewer shows.
Sent file from lap top to P6. P6 paired and accepted. Closed send window on LT and P6 dropped connection. Sent another file and did not click finish on LT and P6 remains connected and LT acts as trusted device for Smart Lock. The purpose here is not having to get frustrated with the FP sensor while at home. Using Trusted Location enables an area with nearly a half mile radius
It's not just bluetooth, it has to do with the Wifi+Bluetooth implementation. You can reliably crash System Settings after a factory reset if you type a wifi password wrong on the same network more than once, or if you attempt to connect to the same network with an incorrect password too many times. Attached "proof" (not really proof but). Once it crashes it'll restart setup but won't let you continue past Network Setup.
I could not get my Android Wear watch (Fossil Gen4) to connect. It was seen once and tried to but the bluetooth stack crashed. Even after a reboot, settings reset, forgot the device, and factory reset the watch it would not work.
My Pixel buds connected via fast pair and "worked", but the phone refused to identify them as Pixel Buds and I could not use the dedicated settings app. Same thing with my Galaxy Buds Live, the Samsung Wearable app would not find the buds even when connected.

This sounds similar to my problems. Try and contact support (took 50 minutes for a call back) and get it into their system.

I'm sorry you're dealing with it I've since factory reset the device and haven't tried crashing anything, so things seem to be working so far. I have an RMA P6 on the way already due to terrible screen tint issues on my phone. Took over 3hrs (1hr waiting for chat to be available, 1hr in line on chat, 1hr on chat)
I may try a reset when I am bored. Gr8 you have a new one coming
