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..

P20 Pro Vibrates Randomly

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?

Yes it did. I force close it and disabled it from app settings. Never came back

Performance and app problems ? U.S. Version...

I am finding that my apps that send notifications, specifically that I send through LIghtflow, are either not notifying, or doing so 30 min. to an hour late.
I am also finding that installing as well as uninstalling apps are quite slow.
POwer saver is not on; battery optimization is not on for the offending apps; they are set to run in the background.
Anyone else experiencing this? Or any suggestions?

Regarding the slow downloads, I am finding the download finishes (according to the status bars, etc), but it then goes into a state of Install Pending. Can't find anything on that.

For anyone who cares, I have it resolved for the time being.
After 2 factory resets, I remembered back to the days i used to root my phones, and remembered that one strongly recommended task in that process was to delete cache.
So I did a final factory reset and deleted the cache also and all seems to be good.
When this crops up again I will try the cache delete w/o a factory reset and see how it goes.

Not getting much help here but I'll keep this thread upgraded.
It is again not working right. Lightroom is either not notifying or it's doing it 30 minutes late.
Play store downloads but then doesn't install for a period of time.
I'm beginning to think something is wrong with the phone.

This thing is driving me nuts. Following is what's going on, and have seen:
I've gone through 4 factory resets. All works find at first. Having decided that maybe there is an app interfering, I installed an app or two, tested, repeat...with delays between repeats. All seems fine.
But then late into the second day, w/o any installs, I goes haywire again. Symptoms are:
I use DGT GTD for my ToDo list. First thing I will notice is that when I add a new task, it will NOT show up in the widget list, and at the same time it stops notifications.
All apps stop sending notifications to Lightflow...or LIghtflow does not recognize the notifications. Not sure which is the case.
When add a new app on the Play Store, it downloads as quick as normal, but then it takes forever to install.​
I installed AVAST, and checked for viruses. Came back clean.
I suspect it could be a phone problem. My Mate 9 works fine right now, with all the same apps. But, when a factory reset results in it working (at least during the short time a tech would evaluate), the phone can't be exchanged.
If anyone has any thoughts. I'm all ears. I'll keep posting, hopefully, ultimately, with a resolution. Maybe it'll help someone.

Mi A2 Problem with Google Chrome

I am having this strange issue when I want to clear cache in Chrome it clears it for a couple of minutes and then crashes my phone and it reboots. Is someone having this same issue?

https://forum.xda-developers.com/showpost.php?p=78257771&postcount=2

You are lucky man, it only rebooted. For me it crashed and formatted. Lost all the data. Don't know it was due to chrome or something else. It was brand new at the time.

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".
