HELP - Notifications not coming through when screen is off

Hi everyone,
I've been having a very strange problem for a couple of days now. Whenever my phone's screen is off and the phone has been idle for some time, I don't receive notifications anymore. Facebook notifications don't work at all, no matter whether the phone is active or not, but I also don't get FB Messenger and WhatsApp notifications. Sometimes they come through as soon as I turn on the screen, and sometimes I only see them when I open the respective app. I didn't mess with app permissions, and I also have set each app to "important" in the notification settings. It also doesn't seem to matter whether I'm on WiFi or on mobile data.
Gmail, SMS and calls don't seem to be a problem, although I sometimes have a feeling that emails come through to my phone with a considerable delay, as compared to my Gmail inbox on my computer.
The strange thing is, when I had the phone all new, everything worked as it should and I received ALL notifications from EVERY app IMMEDIATELY when they came in. This issue with notifications no longer coming through started occurring a couple days ago after I had first flashed the Boeffla Kernel (though I'm not sure if it has anything to do with that.) So I went back to the stock kernel, but the problem was still there. Then I re-flashed my original Nandroid backup from when I had first flashed TWRP, in order to set the system back to "stock", wiped data and cache, re-installed every app (the critical ones, i.e. Facebook, Messenger and WhatsApp, via Play Store, and the non-critical ones via Titanium Backup), and the problem is still there. I've done this three times now, to no avail.
My phone is rooted and I have Xposed installed, I'm using SuperSU and a number of root apps such as 3c Toolbox, Le DPI Changer and Font Installer. 3c Toolbox is set to clear caches on every reboot. As for Xposed, I use only VibrateMode to change the notification slider from all/important/none to all/vibrate/none, and GravityBox to center the clock in the status bar and to set the volume buttons to skip tracks on long press. I also have Glimpse Notifications installed so that the screen lights up when a notification comes in.
The funny thing is, notifications not coming through is one of the reasons I switched to the OPT from the Huawei Mate 7, where this issue was due to power management settings by Huawei. Since I'm now back on the stock kernel and have also no power saving apps such as Greenify or Amplify enabled, I am really out of ideas as to why this happens. The next step is to flash a fully stock OOS 2.1.2 (my Nandroid backup is already rooted and with my Google account set up), wipe data and cache, and re-install every app again.
Does anyone here have any idea what the problem (and the solution to it) might be?
UPDATE: After I wrote the last sentence, I received two messages simultaneously, one from Messenger and one from WhatsApp. I was at home and on WiFi, and both coming in at the same time must mean that the phone receives push notifications in fixed intervals, since the sender of both messages was the same person and sent them consecutively, i.e. with at least a minute in-between. Now I am especially confused since a) they came through at all, even though the screen was off and the phone had been idle for at least 15 minutes, and b) they came through at the same time, which was definitely not the time when they had been sent.
The confusion is complete now ... any input is appreciated. Thanks in advance!

The problem persists. Today for half a day I received all notifications, after that once again only when I turned on the screen or opened the respective app. WiFi all the time, no settings changed in between.
This really annoys me to no end. I don't own an expensive smartphone so it doesn't work as it should. I never had any troubles like this with my old Sony Xperia V. Then again it ate through a full battery in half a day ...

Are you sure you are not using any applications like greenify / amplify or powernap which would hibernate your applications ?

Yes. As I said, I reflashed my original (rooted but otherwise unaltered) Nandroid backup and then reinstalled all apps, and am not using anything that could interfere with apps receiving notifications.
The order in which notifications come through automatically vs. only when I activate the display or open the respective app also doesn't seem to follow any regularity ... sometimes it works as it should, sometimes it doesn't.
As for Facebook notifications, I somehow have a feeling this is a specific FB-related problem. But as for Messenger, WhatsApp and now also Instagram as I've noticed, it's all the same issue as described in my original post. The only exception really seems to be Gmail, which always notifies me of new emails.
EDIT: All these apps have unaltered permissions, i.e. are allowed to keep the phone awake, and all apps are set to "important" for notifications, so this doesn't seem to be the issue either.
EDIT 2: I also installed push notification fixer to see what interval is set for the GCM services, and it's set to 5 minutes on WiFi and 6 minutes on mobile data. So that also can't be the issue.
Could the screen not lighting up when a notification comes in have something to do with deep sleep, possibly? But then why does it work for Gmail???

I could suggest you one more thing. Its a shot in the dark .
Could you check "Keep Wi-Fi on during sleep" in you advanced Wi-Fi settings ?
If the above is not a problem then out of ideas buddy. As a last option you could clean flash by wiping everything and just install whatsapp and other apps in which you are facing a notification delay. If it works then there could be some other application interfering , it it doesn't then i am not sure what it could be.

Yeah, that's pretty much my last resort. Currently, I'm trying to see if it makes a difference whether I keep FB Messenger and WhatsApp "open" in the recent apps menu.

I could try that, you're right - I didn't yet because I didn't want to sacrifice battery life too much ... but I could give it a shot for at least one charging cycle and see what the effect is. Thanks!

i do remember reading some time ago that these intervals do not impact the battery life, but you could test for yourself just to be sure

So, currently most notifications are working again for me, for whatever reason. Facebook being the big exception, of course. Might have to do with keeping the apps opened in the multitasking overview. If that's what it takes, then fine ...

I've got a OPT for few day, i have same issue......anyone experience this problem? any solution? is it 2.1.2 problem?

Which app? Only Facebook, or other apps as well? For me it's working now, but I can't say why exactly. I use a number of tweaks on my phone (root, Xposed framework etc.) so I can't definitely say which of my apps cause issues and which fix them again.
As for Gmail, it appears that when there's already a notification for an email and a little later another one comes in, it won't play a sound or vibrate. That seems to be standard behaviour but I find it VERY annoying, even though I set Gmail to notify me on EACH incoming email.

despite suggesting a fix i seem to be experiencing the same problem as well. it happens on both wifi and mobile data so you cant blame any settings. my best guess would be its because of the latest update. gonna have to backup my data and revert back to the older firmware to solve this issue.

@vonotny have you found a solution? im experiencing the same problem after updating to 2.2.0

Not really, no. Mine are currently working again, after I re-flashed the stock system and set up everything again step-by-step. It's possible that some app or tweak or setting caused the issue, but I couldn't find out which one.

i suspected it could be because of restoring apps from titanium backup directly instead of downloading and installing them from the play store first, but even with that i still face the same problem. currently on oxyslim. come to think of it, could it be caused by the power tweaks? did you use them before when you faced the problem?

Same problem here on OOS3.0.1. Inbox and WhatsApp messages don't often come through until I turn on the screen. Completely stock. Didn't have the problem on CM13, I think. It's really annoying because I can miss a lot of important emails from work. Even put the apps I want in No Battery Optimization mode. No help really.

i have the same problem. I'm on OOS3.0.2 with Cyanoxy. Can anyone help?

Same problem here...
What the F?
This device is almost a year old and I still can't use it as PHONE. I am not asking for some fancy stuff, but fixing the gigantic bugs that are preventing me from even using this daily.

Fix for those willing to tweak the system: install the latest Boeffla kernel, it has an option to turn off doze.

Droid Turbo 2 Facebook push notifications not working, anyone else??

Ever since I bought my droid turbo 2 I have not had a single push notification from facebook, have anyone else had this problem?
I'm wondering if its just related to my phone or if maybe its the facebook app itself.

Yes, i am having the same problem, except mine is with many apps, including twitter, snapchat, youtube, and others. it only happens when i am on wifi. Its very strange and i have tried many things to fix it.

My wife is having problems with the Facebook app crashing when she attempts to use "stickers" or emojis. It will instantaneously take her back to her phone's home screen when she tries. She uninstalled FB and used browser-only for over a week, and then reinstalled last night only to have the same problem happen again. My kids both have the Motorola Droid Turbo (non-2) and they can use it just fine. Must be some weirdness with the Turbo-2...

Yeah my problem is with most apps with the exception of a few. It's so weird. I am starting to think that it might be something in the firewall. I am investigating now!

Disabling battery app optimizations worked for me
Settings -> Battery -> Battery optimization -> All Applications -> Change to "Don't optimize" for the apps you don't receive proper notifications

Well I now realized I have a lot of apps that don't show notifications too, it wasn't just Facebook.

I fixed my problem. It turned out that the version of pfsense (router os) that I was running had a weird problem with my phone so now I am running the latest beta version. And everything seems to be working fine.

well its been a year and I'm still having NO push notifications on facebook, have anyone else had this problem and found the solution?

WhatsApp push notifications (Doze?)

I am having real problems with WhatsApp on the P8Lite. I'm on firmware B564. In short, despite the fact that WhatsApp is a protected app and it is set to "ignore optimisations", I often don't get WhatsApp push notifications until I open the app, at which point I receive a flood of them. I'm also using ForceDoze so I can edit the inactive_to setting to 10000000ms, which if I'm correct should instruct Doze not to kick in for a few hours after I stop using my phone.
Can anyone help me on this? I really don't want to roll back to Lollipop. Thanks!

Solution
Enable background data for Google Play Services app and allow notifications as well for this app.
(PS This solutions is mentioned also in the FAQ from whatsapp )

Do you mean allow priority notifications? Does this override Do Not Disturb, because I don't want that.

Push notifications to apps delayed

My Pushbullet and FB Messenger messages are severely delayed after I switched to the 8 Pro. I've made sure to disable RAM boost, also disabling any battery optimizations for said apps. Yet, most of the time, I don't receive any messages until I manually open the app in question. Not sure what else I should change or if this is a system issue. I never had these issues on my OP6 and used the same settings there. Any help would be greatly appreciated.

Did you also disable Adaptive Battery and Sleep standby optimization under Advanced optimization for Battery?

Yes, I've done that too. So strange that it didn't help. And seeing that it affects Pushbullet, Messengern and Whatsapp tells me it's not specifically app related.

I too have noticed issues with this, sometimes they come through exactly at the right time and other times I have to wake the screen before they then proceed to come through. It seems the battery optimisation settings are quite harsh on wake-locks out the box.

Remove each app from optimization. You should be able to find the app, and it's the settings app and then turn it off per app.

OnePlus really wind me up with their battery optimisations. It kills off the user experience in the name of good battery!

As I said in my original post, I've disabled the battery optimizations for the affected apps, but to no avail.

I may have found the cause and the solution to this, but it's still too early to tell. Most of my apps are restored using TiBu, coming from my previous OP6. I've uninstalled and reinstalled some of the problematic apps clean, not restoring app data with TiBu, but rather from the Play Store. I'm amazed that the app data is automatically restored upon app installation, given that the app itself allows it.
This seems to have done the trick, Pushbullet, Messenger and others seem to be giving me notifications instantly. I did have to disable battery optimization on those apps once more. I'll report back later.
Maybe a dalvik-cache and cache wipe would suffice, I have no idea.

The push notifications are extremely late if the phone remains quite unused, I have set the best but I cannot solve the problem. I need to take gmail emails in real time and this is a serious problem for me, have you found any solutions?

WhatsApp location sharing problem

Hi all
I use my share location sometimes on way home from work, but it doesn't work, as soon as I open the app again it starts to work again?
Seems the app has to be open and running and on to be working.
Not an issue on previous phones, is there a way to allow it to remain running? Seems silly to need to have it on?

Try to not optimize the battery usage on WhatsApp. That may solve the issue. I have experienced delay in notifications with WhatsApp, so I removed that optimization. Normally this solves the 90% of the issues with location, notifications or background processes

WhatsApp location permission setting change from only when app is running to always allow?
