P20 Pro Vibrates Randomly - Huawei P20 Pro Questions & Answers

So, over the last few weeks I've found that my P20 Pro vibrates for no (known reason), every now and again. Usually multiple times per day.
I've tried turning it off and back on, killing the apps, checking for updates, turning notifications off on most apps.
Has anyone had a similar problem and /or has any way of diagnosing or fixing it?

I have experienced the same thing, so you're not totally alone if that helps. I haven't found the cause yet either. I suspect it might be WiFi+ vibrating when the source switches back and forth so it'll happen in stints for me.

i have the same thing and i think i might found the reason, i have some muted WhatsApp chat groups and it seems like that every now and then when i get messages in these groups my phone vibrates although i muted them . There is no notification but a short vibration.
Another thing that bothers me more is when receiving an whats app message my phone vibrates once short and after that the way i set it up in the settings...

I begin to get it after an update. hope to see a solution soon.

No
I believe I've found the cause and solution to the Huawei mate 20 pro random vibrations.
I installed a notification logger from the play store and found that it was logging notifications of repetitive image downloads completing that lined up with every buzz.
If you go into settings, apps and choose to see system apps in the menu, you can force close the download and download manager apps. If you then clear the data and cache from each, you should find the phantom notifications stop.
I haven't had one in days now, and it was all the time.
I hope this is of help.

This happens to me a lot. Its mainly due to voice recognition thinking I'm am speaking to the phone. It happens randomly when watching TV, at work on even in the train. There's no specific key work that triggers it,. It happens at random. This is my issue with the random vibration but your could be a different reason although

Mine was definitely the download manager continuously redownloading Google photos images. Force stop, clear data, clear cache of the download and download manager system apps and mine has been fine now for a week. Try it!

Had the same issue months ago. Cleaning cache and data of stock download manager app solved it for me.

Mine started doing same yesterday ?

I have the mate 20 pro, and it's just started randomly vibrating with no notification
So my phone is now starting to randomly vibrate like bursts of short vibrations that last a while, but there's no notifications or anything? I don't know how to find the "download manager" to check if it's that. I'm not sure which apps to force stop. It's really annoying though.

Do you use Textra? Happened to my wife's s8 and she just uninstalled then reinstalled Textra to make the problem go away.

I have cleared the download manager and everything else several times, but it only works for few days even hours and starts again. I'm not sure if it activities itself again after I download something, but nevertheless, this just shouldn't happen. How can I disable download manager permanently (or preferably just the vibrations, as I assume DM is there for a reason)

Had the same issue. No problem from textra, for me it was google drive. I uninstalled it, cleared cahe and data and I am now using OneDrive. I haven't experienced any random vibrations since then.

Mate 20 X had similar issue after EMUI 9.1 upgrade and turned out to be contacts sync system app constantly trying to sync contacts. Force stop and cleared data and all good now.

I have the same issue on regular mate 20 since the last software update to EMUI 9.1.0. All the suggested solutions here did not resolve the issue. If someone has more suggestions please share

I fixed it. It's a system application called "Contacts Sync" disabling it solved the issue for me.
Settings > apps > show system processes > search for Contacts Sync > disable and force close it

This didnt work for me, but i found another solution. I stopped almost all apps from autostart. except email and messangers. that immediately solved the issue and the phone boots much faster as well, nice sideeffect
You need to go into battery usage and then click on the individual app, then app launch.
I hope that helps

I just noticed this on my mate 20x on 9.1 on vibrate mode. Did your solution permanently resolve this issue or do you have to do it multiple times or after restarts?

[Q] Problems with whatsapp on z3c

Hi guys,
Has anyone had any problems with whatsapp on our phone? The app seems to get killed somehow when the phone goes to sleep, so I don't receive any messages until I open it up. I've not got any powersaver modes running and background data is allowed etc etc, it's getting very annoying and i'm sure the phone is killing a background process but can't work out how to fix it.
Anyone have any ideas?
Cheers
I had a similar issue with hangouts but I cleared cache and data and it worked again. maybe give this a shot for whatsapp
Sent from my D5803
No problem at all.
I use stamina mode all the time, excluding Gmail, Whatsapp, Timely and Cerberus, and I receive emails and messages.
My firmware version is 23.0.A.2.98
I have stamina mode activated all the time but whatsapp works great
Thanks for your replies, i don't what the problem is. The same thing happens if i am in stamina mode (with the app whitelisted) or not in stamina mode.
I have tried re-installing, clearing cache and data etc but the problem perists. I guess i will have to ask the app developers, presumably they will blame the phone

When you notice it start happening, check the "running apps" in settings. Do most of them show "restarting" etc? I think I have the same issue. It looks like a memory leak on my side.
I've seen similar to this but I think it might also be related to when other people have a connection. My wife has issues with her work wifi and sometimes I only get her messages once she's back on our home network. I see the time stamp in whatsapp as the time she originally wrote the message...
Thanks - will check that next time i see it happening, it doesn't look like it has restarted recently but possibly was "pausing". I've restarted my phone now so all processes are on the same clock so i can spot any breaks easier next time

Cheers but seems not likely as messages from multiple contacts appear at the same time when i open the app, so the problem must be on my end
Quick update, i've had the problem happen again and checked the running apps, there was no pause happening. Even this morning on the train i was looking at the internet, so my phone was connected to data and obviously not asleep and i got no messages. Later on, i opened the app and a message appeared, sent at the time i was looking at the internet. I'm flummoxed. Will raise a support call and update if i have any luck

App opening lag when clicking on notification

Anyone experience lag in opening an app when a notification comes through?
When I click on notification for some apps, it'll take anywhere between 3-10min to open. Only happens on some apps. Viber and smartthings are 2 that I have noticed this issue on.
I've noticed some slight lag in apps opening from their notification, but that's measured in seconds, not minutes.

I've noticed a lag of about 45 seconds once or twice. Usually a reboot will resolve it but it could be an errant app or especially if it's trying to retrieve something from the web before showing the window and you have no connection temporarily (poor programming practice) etc...

Only with Secure Folder and only after updating apps in that folder.
Hmm... Maybe an uninstall and reinstall of those apps.. Will try it out once I have a chance to backup.. Must be the way I use my phone.. As same issue was happening on previous phone I was on..
Exactly same failure here. But not minutes, just a lot of seconds. I can click on the notification and then wait, and wait, and wait, open other apps, navigate, and then, suddenly, the app of the notification opens. Very annoying. Lots of apps having this issue.
Reboot the movile solve the issue, but it returns few hours later.
I have never formatted the movile yet, and updated from nougat to oreo. If anyone give us a solution, I think I will format the mobile.
I see there is few people answering this thread, maybe few people having this issue...
never happens at all to me
I have never had this issue, all apps open quicly when clicking their notification
Same here. Stock, updated from Nougat to Oreo.
On my device only notifications from the Play Store cause lag.
It is not that often, therefore I keep calm
I am also having this exact same issue on my Note 9 with 8GB of ram, running Pie O.S. and it is driving me crazy! Someone PLEASE help us figure this one out!
I have wiped phone cache in recovery, even the cache for certain apps, rebooted the phone and in some cases even cleared app data and STILL have this problem.
Thanks.

Factory reset might solve all these.
Thanks for the suggestion, however I always save that option as an absolute last resort.
Hopefully someone has experienced this and has a solution short of a FDR.
Anyone?...
I encountered issues like that more than once. Narrowed it down to /data that causes the issue to happen, as OS reinstall without userdata wipe changed absolutely nothing. OS version doesn't matter. 5.1.1 and 6.0.1 behaved the same.
I've also found that when the said thing happens, you can probably notice another things happening, such as the prompt (when you open terminal emulator app) appears after seconds or sometimes even minutes.
Call recording apps start recording at least few seconds into the call, so short calls in some cases won't be registered at all.
Banking apps will notify the user about ie. incoming transfers with a slight delay.
It's like events - external and internal - get stuck somehow. They can also pile up if you, for example, start another instance in app - you click a button a few times and after some time you'll get those few instances starting instantaneously and simultaneously, just as if somebody lifted leg from a brake pedal. It doesn't have much sense - every single one should be delayed by approx. the same amount of time, but they clearly are not.
Anyway, I'd be very happy if we could figure out what causes that, because doing a complete wipe, even with help of Titanium Backup regarding the restore (did that once, worked perfectly), is not something I'm looking forward to.
I continue to have this issue on my note 9..and now on my note10 plus the issue has returned after over a month of use.. Sigh.. I've completely turned off battery optimisation but no luck..

Samsung Note 8 - individual apps losing notification sound reference

Phone: dual sim Samsung Galaxy Note 8 (SM-N9500) running Android 8.0
Does anyone get individual apps losing their notification sound setting? Recently my Twitter app stopped making audible notifications and when I checked, I found that the notification sound was set to "24270" which is not in my sounds list. This last happened to the default SMS app. Any ideas as to a) why this happened and b) is it possible to globally reset sound notifications?
TIA
Thanks for bringing it to my attention. I've noticed that my N950F doesn't always play Whatsapp notification tones, although I see the LED and notification bar. Rebooting the phone, works for a few hours.
I found this was a problem for a long time, but after doing a factory reset and installing Pie it's all working again. I also had issues with the notification LED that are gone now.
I had the same probleme since pie-update with just one of some chats in telegram. Only one was set to "silense" over night. I had tried first to exclude it from accu-optimization. Next day it was the same, same chat in telegram was set to silence. Now i tried the "apps in standby" under battery->.../settings->apps in standby. If there is your "problem"-app showing up, then delete it from that list withe delete in the right top corner. that solved it for myself, since 2 days now no silnce anymore.
Yeah, make sure any apps you want notifications from are not blocked from using battery or background data in the app settings.
It is probably a software conflict. Try wiping the Cache Partition in Recovery Mode. If that doesn't work backup the data stored on your device and perform a hard factory reset.

I have the same issue with Whatsapp, sometimes, but mine seems to fix itself again after a while. I'm using a modded version of Whatsapp and I just chalked it up to be an issue with that. It's interesting to note the problems other people are having.

Notifications Issue

Is anyone having issues with their notifications not coming through, or coming in super late, or having the same notifications coming up over and over? I'm expecting all three problems, it seems to be happening with every app for me except for calls and text. I factory reset the phone but that didn't fix the issue. If I restart the phone, then all my notifications that haven't physically gone into the app to check start pouring in. No idea what could be causing the issue and it's really starting to piss me off. I have already sent my phone in for repair cause my LTE data stopped working for no reason. I don't think both issues are related as I do have LTE data after they replaced some part.
Would appreciate if anyone has any ideas.
Thanks.

I had notification delays with gmail app, fixed it by turning off battery optimization for this specific app.

Some people may have battery saver on and this may cause late notifications. Also check in settings "auto sync", under accounts. I did have some late notifications issue with Gmail app and do know battery optimization usually is the cause, but it went away in couple of days after I bought the phone.
Thank you for the suggestions. I ended up turning on high performance mode. Let's see if that helps.

How'd this work out for you? This phone is horrible for notifications for me. It constantly doesn't send them until I actually pick up my phone, then suddenly I'll get 5-10 notifications at once. I've turned off EVERY bit of power saving that I can find. I only run in high performance mode 24/7 with all adaptive battery, power optimization, auto app sleep, etc turned completely off. I've also tried disabling all power saving and sleep in the specific app pages as well. I need to be more observant, but I think this is mostly with push notifications (ex, my 2FA app for work) rather than apps with timers to check for updates occasionally. I also have an issue with my wifi disconnecting while the screen is off sometimes which is highly annoying since my home presence detection is based on my phone being on the wifi, though last time it started doing that a reboot fixed it.
Unfortunately, a search proves that this is a widespread issue. At this point I've pretty much given up on this phone and am looking to replace it as soon as I find a suitable alternative. I'm just curious if it's a Samsung issue or a Pie issue that will occur on other phones as well.

Seems to be a general issue with android. Mine have gotten better recently. In addition to turning off battery optimization for any apps I want notifications for, i have done the following:
1. Wiped cache (under settings/app/storage), then rebooted into recovery mode and wiped the cache partition.
2. Gone into the setting and made sure apps I want notifications for are allowed to run in the background (settings/apps/select app for notifications/battery).
3. Allowed to run in background when on mobile networks (settings/apps/select app/mobile data/Allow Background Data Usage.
4. Gone into messages/settings/more settings/push message/changed toggle from "Prompt" to "Always".
Hope that helps.

Thanks, I'll give some of those a try. I also got a VZW update with the May security patch among other things right after I posted that, so we'll see if that helps at all also.

It's gotten better for me. I enabled high performance mode but I had to keep going in and checking it a couple days after still even though it was enabled. Been a couple weeks now and the notifications I was missing before all seems to be coming in fine now. Time will tell though I guess lol
Are you also having trouble with apps updating? That was another problem I was having where I'd see apps needing to update, I'd start "update all" one app would download and then get stuck at 99% and it would just stay like that for about 40mins and prevent the other apps from updating. Then finally when it would finish the next one would do the same. It would literally take hours upon hours for 12 apps to update when it should only take a couple mins. That issue seems to be fixed for me now too.

Question Spotify is acting odd

This might be the app itself but I didn't have any issue on my S20. Since I updated the phone it randomly cuts out. Any ideas? Never on WiFi though...

Is it when the screen is off? Check it's not been put to sleep in battery settings
it seems that latest ROM updates (I think I have this on all AUB* ones) is weirdly strict on background activities and cuts every one of them. my whole device acts strangely - apps not showing notification or showing them late (hours later than they were supposed to show), my apps are not updating: I have to repeatedly FC play store, then clear its cache so that currently installing app changes state from downloading to installing, than do it again to change state fomr installing to installed etc. worked fine on AUA* ones. it is really annoying. btw I tried to clear cache and dalvik/art cache from recovery, but that did not help. I have not tried factory seset yet...
It seems that it was data corruption during regular OTA. Factory reset seems to fix problems for me.
I'll try a reset.. thankyou
Let's be honest, the Spotify app has issues too begin with. On my S21 and Pixel 4 it can be playing songs to my earbuds then suddenly stop running in the background on its own! Unlock the phone and itis still open in the foreground.
Perhaps it's time for a new music app if this is a known Spotify issue... But if it's not a Spotify issue, then check in your battery settings (as others have mentioned) to see if your phone automatically started putting it into "Sleep Mode".
