    Yeah their conclusion to this really pisses me off. This is not a problem with my phone, it is a problem with their software update. There is no way in hell I am turning over my phone to be repaired, I have no other phone and can not be without one. I'm much more likely to buy a different phone and say goodbye to Samsung (which is difficult since Verizon doesn't offer too many other options).

    much the same issue. They landed where I did, it is a doze problem. I have set my battery optimazation to Medium, and then custom, and set the background network usage to on, and it has improved Gmail. I was not running battery optimization before. Still not like it was, but less lag time. Make sure gmail is set to allow it to run in the background.

    There are many threads in many forums for mostly Samsung devices reporting the same problem. There is an occasional other brand reporting the same.

    I'm still on Nougat. I'm giving this another week or so to see if a fix gets pushed out. If not then off to an iphone (wifes iphone gets her gmail notification pronto) if nothing improves.

    So I did a full power down/power up cycle, leaving the phone off for about 5 minutes and it appears to have fixed the problem. No idea why a soft restart wouldn't fix it, but yeah I should have started with troubleshooting 101.

    I'm using a Pixel 2 running Oreo & have had the same issue, started at some point within the last week or so.
    I've been screwing around with it lately & I've noticed in the settings that Gmail simply doesn't sync as often as it should... Is that a problem with the GCM not reaching out to the phone? Or the phone/battery not communicating with the Google cloud?

    Hello and hope all is well! Unfortunately I am experiencing the same issue. On my Galaxy Note 9 push notifications are delayed when my screen is off, sometimes for as long as 30 minutes. Then, when I turn my phone screen on, all of the missed notifications come in at once, sometimes as many as 10 or 12! My Note 9 seems to go to sleep quickly when the screen goes off, and I do not receive push notifications. This totally defeats the purpose of wearing my Gear S3 watch since I have to keep turning on my phone screen to get notifications! I have used Samsung chat 4 or 5 times and tried everything the technicians have suggested to get this fixed, but still not working correctly. I am not running the App Power Monitor, reset all of my apps and have the settings as “high” or “urgent,” did a hard reset of my phone, etc. The notifications do come through, the apps are working, it's just that they are delayed when the screen is off. If this is a problem with Android 8.0 Oreo, who do I contact for a fix? I never had this problem on my Galaxy S7 which did not have Android 8.0 Oreo. My Note 9 already has received 2 software updates in the past 2 weeks, but still the problem exists with push notifications delay. Not sure who to contact to get this fixed! Best of luck to us all I guess!

    The problem is not unique to Oreo. It is happening on my S8 which remains on 7.0 Nougat (by my choice). It is a problem that came from either a Google update or Samsung update that happened in a mid-August to early September time frame. Mine was late August. I have reverted back to using my Nexus 6P which doesn't have the problem. I'm heading toward bailing off Android and going to iOS.

    I noticed Kevsmart has reported his issue returned on his Samsung thread. I don't get the sense Samsung is going to step up to the plate and try to resolve, unfortunately.

    Thanks for your reply. I received the Oreo update on my S7 on August 1 and then these problems began. I purchased a new Note 9 last weekend and was very frustrated to have the same problems on this new $1,000 phone. I've made 5 separate calls/chats to Samsung and they've given me 5 different solutions, none of which worked. Not sure what else to do at this point, unfortunately. Makes my Gear S3 watch useless, I really enjoyed it too!

    I have confirmed this is a problem with Doze, or a fault in the whitelisting process of Doze for the gmail app. I ran the adb command: [adb shell dumpsys deviceidle disable] and notifications work like a charm. On my S8 I have all of the battery optimization off and have all of my apps whitelisted (Samsung: Unmonitored apps in battery optimization) and have had it this way since day 1 with my phone. Interestingly, GMAIL is not an app that shows in the list of apps that I can whitelist, nor can I add it manually.

    The update (Google or Samsung) that was pushed to my phone at the end of August somehow triggers doze as soon as my screen shuts off and blocks the Gmail notifications from coming through in a timely manor. I'm not sure if it is specifically the fault of doze, or if there is a fault in the related whitelist process.

    The ADB test of forcibly disabling doze has eliminated the slow sync/no sync when screen is off problem. My notifications are back to near instantaneous.

    The ADB command unfortunately will reset once the device is powered off and restarted. There is a doze disable app available on the play store which takes a one time adb granting permission to the app, that will address having doze disabled on each power up. Silly that a user should have to go to such measures to get their device working like it did before some update was pushed out. I'm confident fingers would point between Samsung & Google for who is responsible for the needed software fix of my phone.

    This sounds very promising, thank you! I don't use GMAIL though, my push notification issues were with other apps like Twitter, Sports Alerts, ESPN, etc. I am logged into my GMAIL account, I just use another email account. What do I need to do to fix this like you seem to have done? Thanks a million!!!

    The fix for me was to send the adb command [adb shell dumpsys deviceidle disable]. If you do a search on remove bloatware adb there is a good set of instruction on xda forum for how to send adb commands to your phone. This fix only lasts till the next time you cycle your phone. If you can avoid powering off the phone then it can be a longer time fix. There appears to be little success in finding a way for a more permanent fix unless you have a rooted device. The Disable Doze app available on the play store appears to have gone stale with many recent reports of it not working.

    On my phone this appears to be a Samsung induced problem. Convincing them to fix it will likely be tough. OnePlus owners had the same problem a few years ago. There is a hundred page + thread on their forum about it. OEM acknowledged the problem but they still haven't fixed it years later.

    As soon as the screen is off the phone is forced into a fairly aggressive doze state. It didn't do this in the first 6 months I had this device. They pushed out a recent update to some system code (likely for Bixby/Touch Wiz/Experience/AOD) that changed the parameter for how aggressively doze triggers. It may have been intentional to deal with people who complain about battery drain.

    My short term fix will be to apply the adb deviceidle command mentioned above each time my phone gets rebooted. I'm going to alter my phone routine to not power it down each night. Longer term I'm going to move to an iPhone 8 since my work phone does not have this problem (nor does my old Nexus 6P). Might there be a chance that Samsung fixes the gaff? Better chance that the Brown's make the playoffs this year!

    Hello again! I can't thank you enough for your recent posts, I really appreciate it! Unfortunately I am a total novice when it comes to this so there is no way I could do what you did with your phone, even with those helpful instructions. I almost never reboot my phone, only soft resets, so it probably would have worked too. I guess all I can do is wait and hope for a Samsung fix, or at least their giving us the option to reduce or turn off this aggressive doze function on the phone which I don't want. I already have an extended battery on my Note 9 that gives my 9000 mah, so I am fine! I plan on contacting them again with your diagnosis of the problem, and then keep my fingers crossed that they will respond. Unfortunately you are likely right about them fixing this issue, I live in Cleveland and know all about our beloved Browns!!! But hey, we won last Thursday, only took 635 days between wins! I'll look for a Samsung fix in 635 days! Thanks again and best wishes!

    Thanks very much for the adb command. I've been experiencing this problem for the last few weeks after I received the G950U1UEU5CRH3 update on my unlocked S8 in early September. It's been especially noticeable with apps such as Gmail, The New York Times, and WaPo. I have the news apps set to push notifications to my Fitbit Versa. I noticed the severity of this problem when I would wake my screen (after the phone being idle for an hour or so) and several push notifications from the news apps would appear, then I'd instantly receive them on my Versa.

    Today I also started having issues receiving text notifications, but I'm not sure if that is related to the software update or if something else is to blame. My phone started dropping from 4G to 3G, then it would eventually return to 4G. I restarted my phone a few times, then after one of the restarts, I received several text messages at once. I chatted with a Verizon Chat Rep, and they claimed they were having no network issues in my area. I reset the network network settings, cleared the system cache in recovery, and successfully received a few texts in safe mode. However, this happened a second time and the pattern was the same: Drop from 4G to 3G, return to 4G, restart the phone, receive text messages that were sent when the phone dropped to 3G. I went to my local Verizon store and got a new SIM card. I'm trying to do everything I can before I do a factory rest. I really don't want to hassle with that.

    Does anyone know how to disable Doze? Is it difficult (I am a total novice!) I have a Galaxy Note 9 with a 4000 mah battery, and a 5000 mah extended battery so I have no need for Doze. If anyone can help me disable Doze I would greatly appreciate it! Thanks!

    Does anyone know how to disable Doze? Thanks!
    First paragraph of my last post explains how to do it. The xda guide is a step by step to establish the adb connection to the device.

    Once that is done send the disable command I gave above.

    I’m a novice and found it very easy.

    My battery performance has improved with doze disabled.

    Thanks to Al Borland, I got on the trail of this and have now fixed it also. For ease of reading here, all in one place, is what I did after following Al's initial instructions and suggestions from a user at XDA Developers:

    Delayed notifications recently arose because of a problem with Google Android's updated
    Doze Mode".

    The below instructions will fix it. The reason for the batch file is that when you power off your phone, the fix goes away and must be re-done.

    First you need to follow the guide in the 1st link below through step 11 to get ADB working on your computer and get your phone into Developer Mode. Stop after step 11 and then go to comment #83 in the 2nd link below and follow that.

    Finally the 3rd link below, (also round by Al), is a good read from Google to app developers that explains how Doze works and shows clearly the root of the delayed notification problems.

    https://www.xda-developers.com/unins...t-root-access/


    Read comment #83 in the link below where I described my final version of the fix.

    I've had the same issues with my Galaxy S8 with AT&T. Thought it was a software issue. Exchanged the phone under my insurance plan but had the same issue with the new device. I've found if I uninstall the new updates from google play services, I get all my emails, and in-game notifications on time, even while screen is sleeping. Settings, apps, google play services. 3 dots upper right corner, uninstall updates.

    Theses are the thing I've tried to get to this conclusion.
    -Taking all apps out of sleep mode
    -Taking all apps (installed & system) off battery optimization
    -Factory resets
    -Cache wiping
    -Uninstalling & Reinstalling apps

    This is what's working for me
    -Uninstalling updates from Google Play Services
    -Taking certain apps out of sleep mode (The Score)
    -Taking certain app off Battery Optimization (Gmail, The Score etc.)

    I now have been getting my notification on time, for a week, as things happen from the those apps. The downside is I cant get my Google News feed, through Google app, unless I update Google Play Services. I can do without that if everything else is working like it should.

    What is the point of having battery left when important notifications do not come in? (I don't even have battery problem, as my battery always last for more than a day.) I also have problems with Google calendar reminders not going off! (Check the web, I'm not the only one.) I cannot believe how sloppy Google as a company has become. It looks as though the only solution is to avoid using Google products.

    -Uninstalling updates from Google Play Services ---- not allow on my phone (Galaxy S8)
    -Taking certain apps out of sleep mode (The Score) ---- no sleep mode can be found or controlled
    -Taking certain apps out of battery optimization ---- tried but does not work (Gmail not in sleep mode, there is no The Score app)

    I also found that in order to use Maps & Google news feed, you either have to install the Google Play Services update or uninstall the updates from the Google apps ( Maps & Google)
