Mobile network crash on B336 - Huawei P9 Guides, News, & Discussion

So to my great irritation, I recently discovered that the mobile network crash bug that had been fixed in B383 is back in B386. For anyone wondering, I'm talking about the bug where opening "Mobile network" in settings causes phone services to crash and reset.
I'm still not sure what causes it, or what if anything can be reset individually to fix it.
But I do have to fixes for anyone else experiencing it.
The first is to roll back to B383. You can even upgrade again to B386 and it will remain fixed ON UPGRADE but will recur after. I couldn't stay on b383 as downgrading caused lots of Huawei services to disappear.
The second is more reliable. If you switch the phone's primary language to Simplified Chinese (China), you can access Mobile network to change whatever settings you need to, and afterwards change it back. Obviously this is a pain if you can't speak Chinese but it's better than nothing.

I had that, a full reset cleared the problem up.

Yeah but it comes back. Before B383 I had to resign myself to accepting it because it kept recurring.
After I downgraded to B383 and re-upgraded to B386, I only managed to turn the phone off twice before it recurred.
I'd have stayed on B383 since it doesn't seem to affect it at all, but all the system apps that disappeared after downgrading forced me to go back.

[Q] Location Reporting broken after update.

On the 7th I traded my Nexus 4 into T-Mobile for a Nexus 5. On the 8th, I unlocked the bootloader and sideloaded the stock 4.4.1 OTA file. Today, all of a sudden, my location starts showing 35 miles away without me leaving the house. I turned off and on Location services, and it reset back to my actual location. A short bit later, it did it again to the exact same location.
I called Google, they told me to factory reset. I did. When it was booting up and updating apps, it prompted me to install the 4.4.2 update, which I did. After doing all of that, it repeated the exact issue. I went into my Location History on Google Maps online and deleted all the history for today which fixed it. But it keeps jumping back and forth between my Home location and this other place.
I called Google again liked they asked, and they told me to change my Location setting from High Accuracy to Device Only... and to just keep it that way. But it sucks that way. I asked could it be a hardware problem, if so, I would return it to T-Mobile. She said, "I wouldn't return it just for that issue alone." I also told her I was worried it may be a security issue since I had just handed in my old phone, and she guaranteed me it couldn't be a security issue.
Alright well... I'm lost. Unless someone here has some magic advice, I will return it tomorrow.
The attachment is from my Location History and shows the two locations 1 minute apart.
If you are just using 3G then it might be a IP address change on the towers but if you are also using WIFI for location then yeah something is up. I use High and it only uses GPS when using Maps/Navigation. Otherwise everything such as google now and such uses low power anyways.

The entire time I was having the problem, I was at home connected to wifi.
So far today, it has been working like it should and hasn't given me any trouble.
I should probably mention that, along with that problem, the phone was having other issues as well. Google Now wasn't showing me cards, even though my location was working - I was unable to enter my account under the Backup and Reset settings menu - and Sound Search kept giving me syncing errors. Maybe these were all related or caused by the same problem, don't know. After removing my account from Google Now and adding it back as well as some other stuff, I was able to resolve them all.
One other thing I will say is that I was running a sideloaded version of 4.4.1 (unlocked, stock recovery, not rooted) when I did the factory reset, which I thought would reset it back to 4.4. However, when it booted back up, I had a System Update notification telling me to update to 4.4.2, but the file size was only 1.7 mb or so. How did it bypass the size of the 4.4.1 update? Or am I wrong when assuming a factory reset sets it back to its original version?

[Q] Ongoing issue with "Chrome is not responding"

Firstly I want to apologize if there's a thread on this. I tried searching and didn't find anything. Google fails me as well.
For a few months now, Chrome has been driving me insane on my stock nordic Z3 (5.0.2 with the .690 firmware). I also have the most recent version of Chrome installed.
Every single time I open the app, it works for about 2 seconds, then completely freezes for around 15 seconds after which a message pops up stating "Chrome is not responding. Would you like to close it?" If I press "OK", it obviously closes the app and the problem appears again when I restart it. If I choose "wait", Chrome works just fine until the next time I open it. EDIT: The freezing problem started happening three times in a row a few days ago.
This happens every single time I open the app, whether launching it or opening it from the recent apps menu.
I'm pretty certain the problem has been around since the v39 build of Chrome, as 38 worked just fine. I have tried everything I can think of to fix it. Uninstalled updates and re-updated it, updating to lollipo didn't help, I also did a completely fresh install today (repairing via Sony Bridge for Mac) and it didn't help either. And apparently I can't go back to v38 anymore since lollipop doesn't seem to support it.
I would really want to use Chrome, as I've gotten used to it and enjoyed it quite a lot. I'd really appreciate the help.
Try clearing the data in settings - apps - chrome

I have done this too. Also, the problem persists even with completely fresh installs of Chrome.
Remove your google account, restart the phone and restore your google account

Tried it, sad to say it didn't work either. Interestingly it now does the same 15 second freeze, but without the error message in the end. Curious indeed.
EDIT: Got the error message again.
Does this happen on Wifi or on data?
If on wifi is always the same router?

I Use data 90% of the time, and various routers when on wifi. The problem occurs in all circumstances.
Are you rooted? Unlocked bootloader?
You say you are on the Nordic version of .690, is that the original region for the device you bought and the area you reside in?
Can you revert back to KK by flashing a FTF for your device and region and try V38 again to see if that works still.

I have a completely untouched device. So no root, locked bootloader and it's always been that way. Thus Nordic is the original region of my device.
I'd rather not flash back to kitkat, but I can tell you that I tried reverting back to v38 before updating to lollipop and it worked normally without the freezing issue.
This is my version of chrome on Lollipop. Can you update to this? I am also not rooted so you should be able to update to this

I have the same version of chrome as you. The problem has persisted during every single update after v38.
ok without logs I can go no further with this. Is there any chance you can pull some logs off your device?

Does this require root? One of the apps I tried is requiring it and the other one isn't doing much either. Should I be doing something to make it work?

Maybe try the beta version of chrome in case it's a bug which has been fixed but not yet rolled out to chrome. Perhaps try this first as it'll be quicker!
Perhaps it's some data associated with chrome that's getting pulled down after each restore. Perhaps you can try, on a desktop pc, backing up your bookmarks and then deleting them, and clearing chrome's data on your phone, then trying again? And if that doesn't work try getting rid of extensions (not that I think they should be pulling them down as chrome for android doesn't yet support them, although I'm sure I read years ago that one day they would). And anything else associated with your chrome account.
Another one, perhaps quicker (not sure) would be to see if you can associate your phone with a new google account with no previous chrome use and see if it goes wrong with that one. It would help to rule out account-related problems.
Another possibility is that it's not chrome causing the problem but something it relies on; google play services, for example. Perhaps clear data on any apps chrome could conceivably use.
I'm happy to report that my problem is now solved, though still a giant mystery.
My upper speaker broke and I had to get it replace under warranty. I got insanely lucky as they replaced both front and backside glass pieces, the frame, the screen module itself and of course the speakers. So I've now got a brand-new looking phone So happy.
Anyway, I complained about the software being a mess so they also did a complete reinstall and after that Chrome works absolutely perfectly. As magically does everything else too. Not yet a sign of lollipop's previous lagging and rebooting.
It still bugs me, however, that why would Chrome suddenly start having this unreasonable issue. I had tried everything suggested in this thread and nothing worked. My own clean install didn't work. I'm really quite bothered by this.

[Q] "Your system is up to date." No It Isn't! What can I do?

My Shield Tablet recently notified me of the Lollipop 5.1 update. It's not rooted, and not modified. I could download it at the time due to a bad connection, so I paused it. When it resumed later and completed, I tapped to flash and it took me to the System Updates screen, where it told me "Your system is up to date." This is all I can get from it, even when I choose to reset the update data. I know the update didn't install, and when I check the software version, it's reported as 5.0.1.
Is there anything I can do?
I have the same problem. Did you get it sorted? Did a factory reset and still no joy. Says I'm on 5.01 and system is up to date. Annoying
You can try to force method by clearing data from Google Services Framework and close it, then check for update. It might work after quite a few attempts.
Else just flash the update manually: http://forum.xda-developers.com/shi...rial-how-to-debloat-optimize-ota-3-0-t3118187
Word is they've shut off the update server while they investigate some device breaking bugs in the new update. People reporting Speaker destruction due to the update.

Ah ok, i hope they will make hotfix for OTG issues too. Also seems like i have some wifi issues were it lose signal but remain connected to network within coverage areas.

Why my S8+ opens every app after updating/installing?

My S8+ started opening automatically every app I install or update from play store. It's really annoying.. I thought I can fix it with a factory reset, but it didn't help.
What I tried:
- Full factory reset
- Wipe cache partition
- Disable then re-enable play store
- Clearing all data in app settings
What else can I do?
Here's a quick video of the problem right after the factory reset:
I can't see well enough, but I think you phone is updating. What happens after they all update? Does that solve the issue?
For me, it will do the same unless I can get to Play Store, Settings, and turn off "Auto Updates", and sometimes, still then, individually go to the active update list and individually cancel each app before, or as it's updating. It's a PITA

Thanks for the tipp...
It's not normal at all. I'm using this phone since july and never did this before. Yea after the initial setup finished and all apps were updated, the problem still persist. When I connect to WiFi and my apps starting updating, each one opens. Basically, I'm unable to use my phone when the apps are updating.
I had to turn off auto-updating and now I have to start manually updating my apps...
There are many old threads about this bug, besides wipeing cache noone said anything useful to fix the issue.
Yeah, I have not heard of it, but also have not experienced it. If it is annoying enough, and no more simple solution, I'd return to an earlier backup san the issue, or no backup, do a full wipe and fresh install. Something is definitely corrupted, near as I can tell.
Well, luckily the Oreo update fixed the issue.
Hi Feribox, did you do anything different before the Oreo update? Coz, I'm on it right now and this exact thing is happening.
What's even weirder is it seems the apps never close, I have some apps that suddenly just up and play an ad (these are apps that I did install though) so I don't think it's malware.

Updates stuck at 100%, Gmail does not notify, and other issues.

I am desperate, I can't find the issue here. I have a S10 (Xfinity unlocked on Verizon) , I can't seem to update apps, they get stuck at 100% or 99%, AND some things like Gmail and Instagram do not seem to notify that I am getting messages.
Here's the kicker, I factory reset the phone some 5 times now, and still have the issue. The Reset fixes it for a few days (if even a day) and then the issue starts up again!
the phone was just upgraded to 10, but it was happening on 9 also!
no clue what the problem is ! it kills me! Please anyone have any idea? I even had an authorized Samsung dealer do a "software refresh" and then wiped out the phone again, and I'm still having the same issue..
HELP! please.
thank you

Boot into safe mode, it will only load your system apps and not your user apps. Then try to update your apps, if it works then you know the issue is being cause one of your user apps. Then you just need to identify which user app is the offending app.
It also might be caused by a conflict between various settings or maybe you have some things disabled or turned off that are causing this.

That kinda works.. but again, as said, I have reloaded the phone over and over, and it works fine, until a few days later and stars over.. And updating is not the only problem, Geolocating is slow, sluggish or not working sometimes, Push updates of emails are slower or not happening. just weird things..
I am not sure what it could be! its like the phone is the problem!

Ok, everything I posted went completely over your head, I'll try again.
If it is working like it is supposed to while in safe mode(which is only loaded with system apps and system settings and not any of your user apps or data) that tells you that the issue is caused by some user app that you have installed or something in your user settings. In other other words, it is very likely something that you, as the user, have installed or setup/selected, it is probably not the device. It keeps happening after resetting because you are not changing what you are doing that it is causing it, it is something that you keep returning to after resetting the device. You just need to figure out which user app is causing the issue or whatever settings are causing the issue.
The way to do that will be trial and error. Uninstall one of the apps that you have installed, then use the device for a few hours, if the issue continues, that wasn't the app causing the issue, reinstall that app then choose another user app to uninstall and then use the device for a few hours, if the issue continues, that is t the app, reinstall that app, and so on and so on, etc... Get the picture? When you uninstall an app and the issue stops, the last app uninstalled is probably the app causing the issue.
I suggest resetting the device again. Then, only install one of your usual apps but don't install any others and don't change any settings, use the device a while, if the issue does not occur, install another one of your usual apps but don't install any others, basically, install one app at a time until the issue occurs, when it does, the last app installed is probably the offending app.
Or, if you don't find it that way and you get all of your usual apps installed without triggering the issue during the trial and error process, then you need to go through settings by trial and error. Changing one setting at a time and using the device a while to see if the issue occurs, if it does, it probably has something to do with the last setting that you changed before the issue occured.
Slowly changing one thing at a time over an extended amount with time between each change, will allow you to isolate exactly which app or setting is causing the issue.
Or maybe you need to flash your stock firmware via PC tools to start over with a clean installation.
