Bluetooth Bug EMUI 4 - Huawei P9 Questions & Answers

Bluetooth is very bugy on my P9 emui 4... After disabling Bluetooth, it would not get colorless like the other disabled buttons but stay in a state between full blue (activated) and Grey (deactivated). I had severe difficulties connecting to a JBL Flip 3... Kind of embarrassing for a flagship phone.

Hey same problem here! Did you happen to notice that you can't even send or receive files via bluetooth?

First of all, its not ""embarrassing"", dont judge whole series of devices or company, by your separate problem, its like saying that all Ford cars are bad, because your car have one problem... Dont you think its kinda... stupid to say such thing?
As for problem it self, its hard to say whats wrong, I would suggest turning BT on and then off via setting section, reboot phone and then check if it work correctly. Then all what I can think of is checking services(force close them) and checking logs if you know how.
If that simple method will not work... well it would be nice to know your OS version, but as you said you have EMUI 4, and I can just guess that its latest 4.1.1, I can just say "update your phone to latest version"....
And if you dont want to update to EMUI 5, because someone say you that its bad(no its not, people who say that just messed up something), and you want to stay with EMUI 4(damn know why if EMUI 5 is the same if not better), I would suggest you to make backup via huawei app, PC if you have files on phone and google sync, and then factory reset phone.
Last time I did that, with reverting backup it took me about hour, but I had lots of files on PC to transfer, so whole process of factory reset and reverting backups should take about 30-40min depending on your internet and what you backup.

I would love to get emui 5, but that's another matter... I have no idea when I will get it (c150).

We have exactly the same problem on our Huawei P8 lite's (managing 25 devices). So it seems not related to the model. So far no clue how to solve...

[Q] Main GalaxyS bugs or bad features.

Hi! I hope to write in the right area, but if not I ask someone to move my post in the right one.
Now I have a HTC Diamond device, but I've to change it for a GalaxyS or an iPhone4.
I would like to buy a GalaxyS device, but I read many posts about bugs, lags, gps problems, so I wonder if it is a great choice this GalaxyS.
I like android and all the development opportunities around it (thanks to XDA), but it seems to be not so stable yet...
I flashed many ROMS on my Diamond in the past, so it's not a problem to do the same for my GalaxyS, but problems are fixed? The GPS works fine? Maybe not...
Maybe with Froyo 2.2?
iPhone4 is not so open as an Android device, but it's a very stable device!
What do you think about?
coming from a winmo background you're gonna love the galaxy s! its miles ahead in terms of refinements, polish and brilliant integration. The GPS problems are nothing so critical...its more of a sw fix im guessing. I live in India, and i have ZERO problems on my GPS....i feel the bug is something country/carrier specific.
there are many things to love and obsess with the galaxy s....go get yourself one, you sure wont regret it
While I'd love to echo what dreamtheater39 has said, I can't. It's a brilliant phone, but after having mine for just under a month, it's starting to lag like crazy, and in the last two days I've had a ton of dropped calls and the phone has switched itself off/crashed three times in the last few hours resulting in data loss because the power button doesn't respond (forcing me to hard-reset the phone).
All I can say is that, if you do get one, have an open mind. And make sure you don't get locked into a lengthy contract in case things do go awry.
same here GPS working great since day 1

Maybe I got a lemon
Maybe I got a lemon but I can not stand the i9000. I have 4 bugs that drive me crazy.
1. Market Place hangs at starting download. I have to do a factory reset to download an update an app.
2. GPS just stops working or it puts you on a different street when you are using navigation. The worst part is then it has to recalculate the directions twice, once for the wrong location and then again for the correct location, which is a real pain in the pocketbook when you are rooming.
3. Receives invalided cert from a hotspot connects the 1st time then never again. So I cannot use my hotspot at work, my old iphone connects no problem.
4. Does not always switch between wifi and mobile network. Have to go to airplane mode and back to get 3G network. (I tried changing the wifi sleep settings)
Mmmm...so maybe it's a good device, but I understand that who had an iPhone before it seems to be a step backward...is it?

Voice cut during internet calls

I have a problem with my Mate S updated to the latest stock EMUI 4.0.1.
With every app that consents an internet voip call (Skype, Hangout, Whatsapp, Viber) I can listen without any problems my interlocutor but my voice will be cut avery 4/5 seconds for 4/5 seconds each time so that the call is impossible. Only sometime everything works, it seems when the screen is off and then restart to have problems when it is turned on again.
The strange problem is that this happens also with another phone, a Honor 7, so another Huawei phone, and this does not happens at all with Galaxy or other phones.
The problem is present with different internet connections, wifi, interlocutors, so this is not related with the network infrastructure at all.
Could please someone gives me some hints on how to investigate further this problem and kindly tell me if you have faced the same problem?
Many thanks!
UPDATE:
The Huawei official support says that they cannot guarantee the compatibility with Third party Android App so in fact their OS or Hardware have serious bugs and they are not interested in discovering the reason. For them you simply need to avoid using most famous third party app, so do not use your phone like a smartphone.
Please consider buying different company than Huawei if you want to use internet calls

That's strange...I don't have that problems and I'm in the same version, maybe you have a hardware problem.

Thanks for you reply sebastassara. This is the first thing I thought when it happened the first time with my Mate S, in June, but then I bought last week a Honor 7 and I was really sorry to discover that the problem was exactly the same. For this I could not believe that it is and hw issue, or otherwise I would be completely out of luck!
I think more in a OS problem but I am trying to find at least to why it happens or how to solve it, but at least what cause this problem...

Chinese stuff on VIE-AL10 and some apps not working

So after updating to 7.0 there are a couple of things I notice, firstly Chinese stuff like numbers on the dialer, music app, video app, and so forth still persist. The remote app wasn't there after the update so I manually downloaded it, now it is not connecting to devices. Battery is sometimes good, sometimes bad but this is because factory reset didn't work properly after unlocking the bootloader and after flashing the update. So if anyone has any help, and experience let's help each other
I got official 7.0 via OTA and I am really disappointed because battery is really wasted too fast. Google launcher is not working anymore...is closed after few minutes. Bluetooth is sound very bad on my media nav in car, before had no problem. I am thinking to downgrade to 6...

Bluetooth is driving me nuts! Need help please.....

Hello everyone,
I'm having major issues with my Nexus 6 over the past 3 weeks or so.
I've had this phone for almost 2 full years now and love it, however, over the past 3 weeks the bluetooth function keeps turning off when I reboot my phone every night.
It NEVER did this in the past 2 years. Only the last 3 weeks. It seems to be some sort of battery saving feature, I would presume.
What drives me nuts, is I always like to have my bluetooth on, since I get in my truck and it auto connects to my GMC IntelliLink (which is also a problem).
So does anyone know why, all of a sudden, after reboot, bluetooth defaults to off and I have to manually turn it on every time? My Nexus 6 has been flawless up until now.
I've looked everywhere for an "auto start" option for bluetooth, but cannot find one. I have ZERO idea how this happened all of a sudden. I've been running the same ROM since last February with no problems (ROM screenshot attached).
As for my bluetooth truck problem, that started today. All of a sudden "phone audio" will not let me select the box, only "Media Audio" and "Contact Sharing" boxes are selected. Thus my Pandora plays over bluetooth, but my phone calls will not.
Also my Bose Quiet Comfort headphones used to connect perfectly with my Nexus 6, now I'm at work and I notice if I turn the headphones off, then come back and turn on, it'll say "connected to Nexus 6", but the sound is playing through the phone instead of the headphones, even though the bluetooth connection has been established.
Again, this is only over the last few weeks.
Any help would be greatly appreciated.
I'm willing to update to a new ROM or do a wipe, I just tend to live by the motto "if it ain't broke, don't fix it"........ except now it is broke and I want to fix it.
Thank you-
Paste a logcat here. A dev could take a look and help you out.
or
Backup your stuff and do a clean install of a new pure nexus or whatever rom, if it's still present after that, maybe it's just your battery starts to dying after 2 years.
Edit: I'm using crdroid as daily driver and have no bt issues
So glad you posted this, I'm having the same issue! After either a restart or just a period of time my Bluetooth turns to disabled. It is especially frustrating as I have it connected to my watch, which allows me to unlock with smart unlock. When the Bluetooth is disabled, I have to punch my pin in.
I am on stock 7.1.1, February update. I am rooted and flashed the Echo Permissions Fix. I was going to flash stock again this morning, but decided to check here first for a solution. I am just happy to know that it's not just me.
That being said, like @MVLJR, I recently flashed PureNexus ROM and that for me is when this began. I flashed back to stock via flashall, but it has not stopped the problem. Could it be a PureNexus thing?
As we have PureNexus somewhat in common, I am doing some searching on that page. I had previously posted there about it, but I don't think I ever got a response. Someone mentions it on Page 3417, I'll keep reading to see if I find a solution.
My post, by the way, is on page 3420.
I had a problem like this on Pure Nexus and flashed back to stock (N6F26R) to see if the problem goes away...
Previously on stock (release before N6F26R) and never had an issue. I use Bluetooth with a watch, fitness band and sometimes my Wife's Ford...

@muiriddin, did the problem go away for you? Because I flashed back to stock and the problem persists.
@MVLJR, I suspect that the problem is Android Wear 2.0 on our phones. Do you have a smart watch?
Edit: On the PureNexus forum, people without Android Wear are also experiencing it. So back to the drawing board. I still do not think it is your ROM.
Reading this thread reminded me of something I dealt with a while back, I don't know if this will do it for all of you, but I figured I'd post this. I screenshotted a reddit thread that fixed the problem for me. I can't remember if what I experienced was the same as all of you, and I am not having the problem now. But I hope this helps. Please see the attached screenshot.
I don't have an android watch, but I do have a fitbit and don't have any problems with it.
A little update, I cleared my Bluetooth cache and changed the name of my device, which seems to have helped.
My Bose headphones now autoconnect like before.
However, my Bluetooth still shuts off after reboot. My GMC Intellilink still won't let me select "Phone Audio" either.
I think I'm going to flash a new ROM this week, which sucks because I've grown attached to the Pure Nexus ROM.
Can someone show me how to post a logcat?
Thanks
This (and similar) bluetooth issues have been reported on the nougat product pages. It's not unique to PureNexus or the Nexus 6.
Reports are that 7.1.2 (beta) fixes the issue on devices that have access to it. Hopefully a fix comes down the pipe for the Nexus 6 as well, as I have some of the same issues.
Similar posts can be found on the nexus6 and googlepixel subreddit pages.
My question is, what prompted this?
I've had the same ROM for a year, no OTA updates. Had to be an app update, correct?
No other way to explain how it worked for a year, now problems all over the place
You've been using the same ROM, but updating the version of the ROM, correct?
And the ROM updates are based on updates made to Android by Google.
So if a bug makes it into Nougat, it will (generally) make it into the modified ROM as well.
Incorrect, I've been on the same version of Pure Nexus since last February, screen shot in original post
I take it the fix I posted didn't help? I was really hopeful that it was the same issue and that would fix it up.
I haven't tried it yet, at work right now, I'll give it a shot later.
I'll update my findings.
Thanks
Will keep my fingers crossed. One thing to note, when doing that fix, it *will* wipe your bluetooth auto-pair devices. So don't fret if nothing automatically connects afterwards. You have to repair everything.
It is not a new problem, there are many threads in the Q&A forum if you search. Here is one:
https://forum.xda-developers.com/nexus-6/help/bluetooth-off-reason-pattern-t3435436
(there are more links and suggested workarounds in that thread from me)
That said, installing the AW 2.0 DP 4 totally solved my BT disconnects from my Huawei watch and LG stereo headset.
The changelog on the latest Huawei AW 1.5 mentions BT issues, but I have not tried it.
AW 2.0 official is supposed to start rolling out OTA tomorrow, so we shall see. (finners crossed tite )
I'm on Jan 21 PN 7.1.1, latest AW app. I have no suggestions of those having issues with no Android Wear, but there are threads here with suggested workarounds that solved this for many of us before, you might want to check them.
@Morpherios and @MVLJR
I don't know if it's of any note, but one of the actions I attempted in trying to fix mine was to reset all network settings via the "More" option in Wireless & Networks settings (I backed up wifi settings in advance). That's essentially a nuking of all network settings, including wifi, cell, and bluetooth. It did not resolve my issue.
@Pkt_Lnt seems to be indicating that with updated AW on his watch, the disconnects are not happening. How the software on the watch (as opposed to the AW app on the phone) would be causing bluetooth to crash, I'm not sure. But it's not outside the realm of possibility.

My words were / are different than that:
AW 2.0 DP 4 totally solved my BT disconnects
That means they do NOT happen any more, since Dec 11, 2016 when I installed AW OS 2.0 DP4 was released and I installed it on my watch. Not. One. Disconnect. None. Nada. Zero. Zip. Zilch. Nein.. :victory:
BT devices communicate both directions. The watch CAN control the phone, and was turning off BT. It was obvious when it happened, when my headphones prompt "Out of Range, trying to connect" (I came to hate hate that voice prompt )
I would immediately open the AW app on the phone at disconnect and was prompted to turn on BT because it was off.
@Pkt_Lnt I completely agree that it BT communication is two-way...I stated that it's not outside the realm of possibility because there are a number of factors that could do it, including the phone receiving a message it simply doesn't know what to do with and causing a fault. This could explain my bluetooth share crash messages that I received on occasion.
It's encouraging to know that it's fixed with AW 2.0 for you. I hope it carries through to me when I get the update. If the OTA doesn't drop tomorrow, I may have to flash the DP as well.

Are major problems solved in the latest firmware? (Restarts, wi-fi & BF dropping...)

Are major problems solved in the latest firmware? (Restarts, wi-fi & BF dropping...)
Hi,
I want to buy XZ1 compact but I am reading this phone is restarting on its own, and has wi-fi and bluetooth problems. Can anybody please say, if those or other "critical" bugs are solved? I searched but it is hard to say for sure...
Basically I am quite depended on the phone and I really want it to be reliable. My current Motorola restarted maybe once in three years, so I am bit nervous about this.
Thanks
I'm on the latest firmware and I don't have any of that.
That said, I was on the November one for the last few months and also never had any of that.
That's the problem with forums like that, you're likely to only see the rare negatives of any device.
No issues for me.. smooth as butter.. great battery life.. LDAC working flawlessly with Sony headphones etc
Just wish I could turn the charging LED off
Also keep in mind if you unlock bootloader and load custom rom you're on your own. I havent gone that route this time and have had literally 0 issues in months
Okay, thank you, it seems it will be fine. I won't do custom rom but yeah root + xposed is a must for me.
I also got dropping WIFI. Really annoying and nothing seems to fix it.

Wifi working fine here. Check the settings on your router.
The restarts seem to be fixed. I think it was a regression with the previous one or two versions. The phone was fine, then it went from one or more a day, to none with the latest update. Wifi hasn't improved, but I did not find it that bad to begin with. Once it connects, it stays connected. It's that original connection where it sometimes decides "wifi? I don't have a wifi radio." Bluetooth is still terrible - works fine with a BT speaker, but is nearly useless with a car stereo.
Only 1 problem persists - Smart Lock don't work, it just a blank page. Can be resolved by restarting the device.
