Notifications suck. Why are they so delayed and random?

What's going on with notifications? They are showing up at completely random times on my Pixel. Just got a gmail notification from an email that arrived 3 hours ago. This has been happening constantly. I wake up in the morning, look at the phone, see no emails, then suddenly a bunch pop up. I thought it might be related to some sort of doze feature, but it's happening even when I've been using my phone quite regularly.
This is ridiculous. Never had this happen before.

I agree. It's gotta be doze.

I'm shocked this isn't a widely discussed topic. It's happening non-stop. I just missed an email fro 4 hours ago and I was even using my phone several times to make calls during that time, so it wasn't even idle.
WTF is going on?

I KNOW YOU SAID GMAIL APP
However, a LOT of apps are not updated for 7.1 so any number of old apps that control notifications in some way may be breaking things.
It sounds exactly like something is interfering with the ability of phone to check or deliver notifications on time. Like a faulty app making a request or insisting some loop then crashing finally and allowing notifications through.
I think Doze is interfering with SOME of my notifications, but my problems don't seem as severe as all of yours.
You can troubleshoot by removing old apps and testing if notifications are blocked, then add apps back 1 by 1.

i noticed this non stop until I disabled battery optimization for those applications (calendar, email, messenger, gmail, etc). Battery is still fine and I have zero issues with notifications

It would be *really* interesting to know exactly which app's (the full list? you disabled battery optimization on. Could you list them all in more detail?
I just disabled it on Calendar, Gmail, Messenger and I am still getting delayed notifications in Gmail!!!
This is a *BAD* problem, Google!
I know people who had this exact issue on the Nexus 6P. It made the phone *unusable*. The Pixel may not be quite as bad, but it's not acceptable to me.
I'm wondering if some of the other "Google Services" like all the "com.android...." app's or maybe some of the qualcomm, like com.qualcomm.fastdormancy maybe? I guess I can start trying them, but there are a lot, so if you know the key ones, it would help.
Thanks for any further info.
P.S.
Apparently this problem with Gmail is discussed here -- many have had this issue. Google should be ON THIS or they will lose customers:

Ok... I just installed Maildroid Pro and didn't see the problem with it, and coincidentally also received Gmail messages at the same time... even after uninstalling Maildroid, Gmail is still now showing notifications... but perhaps the delay is just still random. Like some component of the OS happens to be loaded right now or "not dozing" and so everything is fast... but time will tell if the delay comes back.
This really needs to be fully ironed out by Google. How can they release brand new devices that don't receive timely notifications?? Isn't that something "mission critical" that you would test? This is a major error by Google -- hope they fix it fast, but some people have been waiting for a year with their Nexus devices and apparently it's still not fixed, even on 7.1.1.

Happens on my 6p too. Definitely a 7.1 issue

Most likely an individual application problem. It's not the phone or it would affect all apps.
I get timely notifications for text, calendar, and Keep. I don't use notifications for email so cannot comment on that.

It does look like perhaps turning off the battery optimization for Gmail may have fixed this? Either that or my phone just hasn't yet had time to go into "deep doze" vs. lighter doze. I'll be watching during my 15 day potential refund period . Other than this issue, there are maybe a few minor tweaks that would be nice, but it's otherwise an amazing phone so I want to keep it!

Notifications on the Pixel phone are pure garbage IMO. Half the time I don't get one really. Either the LED light does not light up or Ambient display does nothing. Love everything about this phone except notifications. I am almost thinking about switching to the Oneplus 3T because of this...I hope Google is aware how crappy they are on this phone....

As a member pointed out, it's not the phone but something in 7.1. So no point saying u will return the phone. On my OP3 also i had delays in notification using cm14. So ya it's probably something software related and can be fixed easily.

Hmm weird that I'm not seeing this issues. If Gmail is giving your the issue use another email client?

See topic at Pixel support site:

My post there:
I'm actually a Pixel (Android 7.1) owner now (never mind my user name). I've had the notification delay issue too -- mainly on Gmail. I disabled battery optimization and that seemed to have helped some during the day when I use my phone from time to time. What I noticed is that after leaving it sitting at night (tho' still plugged in) it seemed to have entered "deep doze" perhaps (tho' it's not supposed to while plugged in, if I understand that correctly). At any rate, it missed a Gmail notification in the early morning, but then after "waking up" the phone it seems to have been acting normally through the rest of the day.
I have a Galaxy S7 that I was using as a test comparison. It's on Android 6.X (Marshmallow -- also supposed to have doze) and it got an email notification no problem this morning when the Pixel failed.
Google really needs to listen to this and fix it!!! Professional business users cannot afford to miss email notifications!!!

The problem is also on 7.1.1 not just 7.1

Gmail gave me sync issues (and therefore delayed notifications) on my g4 with 6.0 once. Couldn't get it to work until I wiped the data for it.
On pixel, you also need to be sure the data saver option isn't the culprit. Either turn it off, or make Gmail an exception. That option will cause delayed notifications for nearly any app, as it won't be syncing hardly at all on mobile networks.

Unrestricted data usage (i.e. no data saver) and background data are both set to "on" for Gmail in my Pixel (7.1)... battery optimization is also turned off.
I now believe the problem is associated with "deep doze". I appear to get Gmail notifications ok during the day, but if the phone sits idle overnight, then by the morning I will NOT receive Gmail notifications until the phone has been woken up. I actually have to manually check / refresh Gmail and then after that it appears to be "awake."
This problem is really serious -- very unprofessional to not have timely notifications in a "professional" device / OS. Android / Google teams need to escalate this. I've seen reports since way back in 2015 on Nexuses.. some people have pounded Google w/ requests for over a year and this is still not fixed yet!!!
There must be a way to fully disable "deep doze" for an app and all related services required for its operation.
This tempts me to consider delving into AOSP and cooking up a ROM which would give total control over doze and anything else needed to make the phone actually *work*.

so at the people who got problems... do you marked the app that are effected in the settings/battery opt-out for the battery improving option in standby so they can stay connect for push?

I have delayed gmails on my xperia z3. Always have. If you want an instant message, use an instant message client. Emails are seen as something you can wait for, to save battery life. Obviously if you are also having delays on Facebook Messenger etc then you have some other problem.

That's hardly a solution. That doesn't fly in the business world, nor do I would I want companies and clients messaging me on a bunch of random instant message apps.

In the "business world" - that is, on my work pc - my emails arrive immediately. But i'm not using gmail on my phone. You probably want something a little more robust if you're going to rely on emails turning up immediately. They were never designed to be instant, or secure.

facebook app notification sound retention on nougat - anyone have problems with this?

My S7 edge is running android 7.0. The latest release of the facebook app will not *stick* the notification sound I've selected under the app's notification settings. It stays on the sound/ringtone I've selected only until I reboot the device or force stop the app. I've tried clearing the cache and deleting the data - no change. I've also tried reinstalling the app - no change.
Is this a bug? Is anyone else experiencing this behavior on their device?
Thanks

In response to my own post -which often happens here on xda- my issue has been resolved. As it turns out, the latest public release of Facebook (v132.0.0.20.85) is seemingly plagued by a bug that reverts the app's user-selected notification sound. Apparently, however, not many folks are upset about this, since there's virtually nothing posted about it anywhere. It bothers me because I like unique notification sounds for each of my apps. That way I can tell which app has received a new message without looking at my phone's screen - it can be handy.
To resolve the problem, I simply downloaded and installed the beta version of Facebook (v133.0.0.16.83). I then tested it, and voilà ... the notification sticking problem was history. It would've been nice had someone replied in this thread to let me know that their installation of the most recent public Facebook app was afflicted with the same bug. That way I could have deduced how to fix the issue much sooner. But I guess it's a lot of trouble for most folks to simply type, "mine does that, too." Admittedly, it's not a huge issue... but it's certainly an irritant.

Samsung Interface Not Updating

All,
First time poster, frequent visitor of XDA Forums. I've come across an odd issue that I don't know how to solve and I'm hoping some of you smarter than me folks can get me squared away.
I have a Galaxy S8+ from AT&T running Android 7.0 and Samsung Experience 8.1.
Problem:
I've recently noticed a delay or completely non-updating interface on my phone. It updates on occasion, but I can't determine what triggers an update. For example, I will pick up my phone from the desk and when I press the power button it shows the accurate time. When I unlock the device, the sense flip clock I use on the main home screen shows an earlier time (could be 30 minutes... could be a few hours). I don't believe it's just the Sense app because I noticed this issue where I checked a facebook messenger app that came and and when I closed the app, it still showed I had 1 notification. I went back in thinking I had another new message, but I didn't. So it was still hanging on to the notification. It happened a couple times with a text message as well. Most importantly, my calendar doesn't alert me prior to an appointment either, even though it's showing in my calendar and an alert is active. If I save an event, and exit, I can normally see the event appear on the on widget immediately as well... but that hasn't been happening. I have to press the widget to open it and confirm it is there (which it always is). Eventually it refreshes and shows up. But that delay is likely the reason why I'm not getting my alerts.
All of this did seem to happen after a recent update Samsung/AT&T pushed out but I don't know for sure. I tried clearing the cache from the boot menu but it doesn't seem there is wide success with that.
And perhaps I'm just not a good enough user, but everything isn't all backed up in the cloud so doing the factory reset to me is always a fairly large task as I have many things to manually transfer out and then back in. Not sure if there are great tools that help with this on a stock phone.

BUMP

try disabling battery optimization for those apps.

It seems that you have several bugs and if they all start happening after you have installed the latest update, then expect a patch coming soon.

I have actually done that. Found very limited success. I'm also finding very few results on this topic. Surely it's not just me though.
And I'm dreading the idea of a hard reset as I have many things on my phones, not all of which is sync'd to the cloud so it's a task to back things up appropriate. Specifically regarding "encrypted" apps like my password keeper app etc.
It would be great if there was a software application that allowed you to backup whatever is necessary to not lose data, then wipe the phone and instead of just simply restoring the full phone (which is likely to create the same problem one had before the hard reset), you could simply dump back in app data as needed. It would also help diagnose if the problem lies in a specific app's data.

High level overview of issues...
I have the Ring Doorbell app. I get notifications after "live". Could be 5 minutes, could be 1 hour... or possibly not at all. I have the app setup on my wife's iPhone and she gets them immediately. If I restart the phone, I will get notified right away (it's like it runs the app again and then I get the notification). Keep in mind, this is AFTER i disabled the battery optimization feature for the Ring app.
I also notice it occasionally with texting. I won't have any text notification in the notification panel, nor will my messaging icon have a little red circle indicating a message is there. But if I open the app, a specification conversation will have a red circle indicating a new text is unread.
All of this is leading me to believe the Samsung UI itself is not updating and therefore notifications that actually have arrived (from whatever app), are not displaying because of the UI and not because of their own delay.
Because of this concern I have turned off battery optimization for "System UI", "Themes", and "TouchWiz Home". I have not seen any change however.

[Solved]
I was able to determine by various other threads around the web (thought for sure I'd find it here, but I didn't) that the culprit might be the Google app. Supposedly it was fixed in some prior release, but it's not on my Galaxy S8+ w/ AT&T.
Once I disabled the Google app all the odd issues with notifications and clock interfaces and app icons not updating went away. The downside to disabling it is that I lose the Google Assistant functionality which stinks but otherwise there is no impact to using the phone. I re-enabled it at a later date and it worked fine for a few days and then started acting up again. Once I disabled it, the problems all disappeared. Clearly Google app is to blame.

Samsung smart switch works wonders, the only thing that doesn't restore is passwords, you have to have and external SD card for it to work, or plug it in to a computer

That is not the issue. As mentioned, it's not just the clock it's multiple interfaces.

Mysterious bug: Receiving notifications reboots apps

I have crawled the internet and XDA and have yet to see anyone else mention an issue I've been having with my Google Fi Pixel 3 since launch. On random occasions, when receiving a notification, whichever app I am currently looking at will either completely restart, or seemingly force-"refresh". I am baffled.
Examples of issues I've had when receiving notifications:
- While playing the game Brawl Stars. The app entirely closes and reboots.
- While viewing Instagram feed. The app refreshes and brings me to the top of the feed as if I'd left the app.
- While browsing in Relay for Reddit. Feed restarts at the top.
- While browsing in Chrome. The webpage crashes and is entirely reloaded.
- While viewing the Recents multitasker. Closes the multitasker entirely and drops me on the homescreen.
At first, I thought perhaps this was a RAM issue. Since it doesn't happen every time I receive a notification, I've thought that perhaps the System UI and/or Pixel Launcher (which controls multitasking now) was getting dumped from memory and forced to reboot. But I honestly have no idea. None of these have been easy for me to reproduce, it just randomly happens when I'm browsing my phone and receive a notification.
My phone:
- Pixel 3 128GB
- Running latest December update (also happened with launch version)
- Using Pixel Launcher
- On Google Fi with an e-SIM
- Have two system user profiles set up (one personal, one work). They both exhibit this behavior.
- I use Developer Options for USB Debugging and not much else (I'm an Android software engineer and use my phone for work)
- I never install sketchy apps and am pretty vigilant about that. Mostly just have work and communication apps, along with a few games and music.
Here's what I've tested:
- The December update. Didn't fix anything. Had marginally better RAM management, but it still happens seemingly as frequently.
- Changing launchers. Used Action Launcher, and still had the same issues.
- Disabling "heads-up" notifications system-wide w/ ADB (which I originally thought was the issue). Still happens when a notification is received, even if just silently added to the notification tray.
- Disabling Notification Access to all non-system/important applications. Thought it was an errant app being triggered. Changed nothing.
- Checked the Notification Log system settings for any strangeness in received notifications. Couldn't find anything obviously out of place.
Potentially related issues that I'm not sure about:
- System UI will very rarely completely crash (randomly) and boot me back to the lock screen with no explanation. Only happened a handful of times.
- The Recents multitasker can sometimes become glitchy when using gestures. Every so often, triggering it causes the whole multitasker to flash several times before it displays correctly. Like it's being rebooted from memory (a theme here...).
I'm getting desperate. I've been a big Nexus fan since the Nexus 4 was my first Android phone. I had the OG Pixel 1 and had none of these problems whatsoever (by far the most solid phone I've ever owned until the battery crapped out). I was hoping the December update would fix this, but this is plainly unacceptable for a phone I spent $900 on. I really don't want to hard reset the phone if I don't have to (since I'd have to set up all my work and personal profiles again...) but if it's the only option then I'll do it!
Does anyone here have any thoughts?
