Hi everyone,
I have had the Moto G 2nd Gen for about 10 days now and I have noticed that notifications from several apps (Exchange email, Gmail, Whatspp, Facebook...) are either delayed by a few hours or don't come at all. This happens on both Wifi or my network. Has anyone else experienced this ?
I have tried the following with no success:
1- disable Wifi optimization
2- factory reset phone
3- Installed PNF No-Root and set hearbeat to 5min
4- Cleared data & cache of apps
My phone is not rooted running 4.4.4
Thanks
Yes I am having the same problem this is my thread on the subject:http://forum.xda-developers.com/moto-g-2014/help/notification-problems-t2875216
I have tried 1, 2 and 4 of your attempts to fix it to no avail.
Before I reset the phone all notifications showed the correct time that they should have come, for example if I slept the phone at 10:40 and a notification came at 10:44, I then woke the phone at 10:50 the phone would immediately buzz and sound but it would say the notification came at 10:44 in the notification draw.
However after the factory reset of the device in the same situation the notification draw would show 10:50 but I know that is wrong because WhatsApp for instance will say the correct 10:44 timestamp on the message in the app.
Notifications when the phone is awake come through perfectly every time.
The problem is actually not limited to just notifications, I play music from my phone, when the the phone is awake it plays perfectly, when you sleep the phone, the music will carry on playing but occasionally it will have a hiccup where it will stop playing for a split second then carry on, and sometimes at the end of a song you expect the next song to start but it never will, if you then wake the device the song will start playing like nothing was wrong (exactly how the notification problem is).
I don't know what the problem is I suspect something to do with bad software or faulty hardware if there is a specific part of the hardware that only comes into play when sleeping (I don't know if there is or not).
What are the specifics of your phone? Mine is a XT1068 8GB Dual SIM Retail GB completely stock 4.4.4, the system version is: 21.11.14.titan_retgb.retbgall.en.GB retgb, will be good to know if this affects specific versions of the phone or any version, to narrow down the problem.
The problem is also completely random I cannot 'make' the problem happen it just does.
Mine is the same as yours XT1068 8GB Dual SIM Retail GB 21.11.14.titan_retgb.retbgall.en.GB retgb.
I also have the same problem with music, I also noticed this with chromecast, it seems to loose connection after playing one track.
I contacted Motorola assist and they said replace the phone. I'm not sure if replacing it will solve the problem, I'm guessing this is a software issue. I
I got it from Amazon UK, I'm thinking of returning this and going back to my Galaxy Nexus and wait for the new Nexus phone.
Because we have the same software version I more strongly suspect this is a software issue now, I'm not sure what to do, I don't really want to return the phone as I will be left phoneless and a replacement would just come with the same software.
Another option would be to re flash to a different software version (an international version) but that will invalidate the warranty.
Not really sure what to do, would be good hearing if any retGB people are not having any problems, if any are reading this thread? or if any non retGB are having this problem.

:\ it doesn't look like that app fixes it even when changing the interval to 1min.
I've sort of found a way to at least make it happen to test stuff, using 2 devices I have installed Telegram on both and set each device up with different numbers so I can message from one device to the other, using the other device to the Moto G if I send messages sometimes the notification is instant, sometimes it is a minute later, there is no pattern on whether it will receive it instantly or delayed, however waking the device will always make the phone buzz if it is delayed.
If I add my tablet into the mix (tablet and Moto G on the same number) the difference is very stark, sending 5 quick fire messages the tablet buzzes for every message, the Moto G may buzz for the first and maybe the 2nd but then nothing for the other 3, or none at all, or none and then double beep on the last message or a little time after the last message. (all this is on WiFi)
The best news is that it has eventually beeped within a couple of minutes for every message, but in a conversation on WhatsApp a couple of minutes is a long time.
Again if the phone is awake or playing music while sleeping it works perfect a beep for every message every time (WiFi Again). (I know PNF is only a partial fix for WhatsApp and Telegram but I can't test it easily with Gmail and the main concern is WhatsApp as I want those messages without delay)
It's definitely something to do with keeping the phone 'active', if it's playing the music it works, if it's doing nothing it is literally like it's sleeping on the job.
I'm going to test on 3G but seems to work almost perfect so far (I haven't really used my phone on 3G much as I'm normally on WiFi)
@katkat911 can you tell me about your WiFi setup it isn't TP-Link is it? because I'm wondering if it could be a WiFi setup issue as my phone originally couldn't even detect my router until I changed some settings. (I know you have the problem on 3G too)
Apologies if this is a bit rambly I want to put my casual findings out there in order to let others have the information.
Been testing on 3G, after the phone is slept all notifications work perfectly for 10 minutes with the phone buzzing a second or 2 after my tablet, if you sleep the phone and send a message after 10 minutes the phone will only buzz after 30 minutes from being slept (ie the heartbeat).
I've reinstalled PNF app and will experiment more tomorrow, still not sure how I will fix WiFi but I think a little more experimentation is required (yet doesn't make sense why my tablet always works 100% and the phone doesn't when using the same router)

I agree with you that it has something to do with phone going to sleep. My WiFi router is Netgear. I have they same problem with every other WiFi network and also on 3G. I didnt have this problem on my previous phone Galaxy Nexus.
PNF doesnt seem to work at all.
Notification problem is proved. I also have the issue. that 10 mins theory is absolutely right. as both of you have done good research, I would suggest one of you create a question at https://forums.motorola.com/hives/e3ec93b1d7/summary and summarize all your findings. Some one from Motorola will respond definitely. I see this as a deep sleep issue with the kernel. Once submitted, you can share the link of your thread here. I and others will comment confirming this as a common problem.
You may have to first register with your moto id or may be google id.

I have posted this on the Motoral forums here https://forums.motorola.com/posts/dbb4806484
I have been experimenting again today, the problem is significantly worse on WiFi notifications are much slower than on 3G, the problem seems completely unreplicable, sometimes notifications come though aOK even after I have left the device sleeping for an hour (using WiFi) or sometimes the notification will be delayed for several minutes even if it has only just been slept (again using WiFi), 3G on the other hand there is a definite 10 minute cut off from sleeping the device.
I've had PNF installed since last night and it doesn't help WiFi at all, but 3G it might, I say might because sometimes after 10 minutes (even an hour later) if I send a notification I do receive it straight away (something that never happened before I installed PNF) but then sometimes it doesn't and it's delayed for several minutes again.
I will join the Moto forum and add my weight to that when I get back to my computer as you need to sign in with a Google account.
I've also noticed that if the phone is sleeping whilst charging notifications work flawlessly in much the same way playing music while the device is sleeping they do. I've posted this finding in the Moto forums as well.
Fingers crossed we get a solution :fingers-crossed:

I have also noticed that. It seems that many are having this issue, so far no reply from Motorola
Motorola might be investigating about it. Yesterday i went back to dalvik from art. I tested the notifications the while day. On Wi-Fi, i didn't see the delays any more. In 3g many tests were successful even after 1hr of deep sleep. Only at 4pm India time i found a delay of 22 mins for whatsapp notification. There i also realized that it had switched to 2g due to bad signal in that room. I was definitely having problem when i was on art. Last night i also got the ota for build 23. I see that the kernel is updated. I will monitor one more day and report here.
Motorola has at least seen the post even with no reply, I just hope they are busy behind the scenes working out what is wrong so they can fix it.
I've never used ART (I'm completely stock), and all the problems are still happening today, unfortunately Telegram is being DDoS'd today so haven't been able to test anything out.
It will be interesting to hear if the update you received helps in any way, esp with the updated kernel, since your retGB device received it hopefully ours may do soon too.
As far as I can tell it doesn't affect calls and SMS, but I simply don't use SMS or calls at all (WhatsApp ftw) so my testing has been the odd 'prank' phone call from my 2nd phone and it rings every time, but it's not enough to confirm if it's a fluke or if in fact it does not affect phone calls/SMS.
SMS and calls won't be impacted due to this. It's mostly related to deep sleep state of the phone. It will impact data connectivity mostly.
I have been testing as and when possible after the update. On Wi-Fi, I didn't see any delays for WhatsApp, Facebook notification, exchange mails through nine app even if the phone was in sleep mode fur an hour or so. I saw 1 min delay in Viber twice.

That's good news, hopefully the update has indeed fixed it, there's no indication when the update will hit the UK but if it does fix it then ASAP I hope.

How is the phone with the new OTA update ? are notifications still delayed?
There's still no word from Motorola

In a different thread Motorola amin had mentioned that they are investigating the notification delay issue. I don't see much delays after the update. There are few mins here and there, but mostly good. If you haven't received the update yet, check the ota thread and update manually. It's the same update. Then see if you find any improvement.
I got the OTA update yesterday and I'm still having the same issues
I have updated to the lollipop update like many and my phone is warm and sometimes hot.
I am not using my phone and it still gets warm and drains the battery life.
In 4 hours I will go from 100% to dead with no use.
My screen was off but shows it as being on. **See attached photo
I searched the MOTO threads and cant find anything as of now to resolve this issue.
Anyone else having this issue and find a fix?
Tried wifi channels to see if this issue fixes this, cleared cache and nothing........
Hope help comes quick!
If I can get some help I will buy them a beer or coffee!
Okay here's an updated seems to fix the issue......
I disabled the WiFi location settings, download clean master -- https://play.google.com/store/apps/details?id=com.cleanmaster.mguard -- and seemed to have fixed the issue so far.
Keep you posted as the day goes on.
After you updated, did you do a factory reset? If not, and before you do, what apps do you have installed? You might have an unruly app that's just constantly running. I hear Google Fit hasn't been too friendly...
Since Google services is pretty high on the usage list, it could have something to do with syncing errors or maybe problems with updating Google Play services/Play Store. Make sure you have the latest versions.
Google Play services (6.5.85) - http://www.apkmirror.com/apk/google.../google-play-services-6-5-85-1589008-438-apk/
Google Play Store (5.0.38) - http://www.apkmirror.com/apk/google-inc/google-play-store/
Also, unsync any services in your Google account that you aren't using.
Don't forget to turn off extraneous radios like WiFi (if you don't use it for location), GPS, NFC, and Bluetooth when you're not using them.
If all else fails, factory reset and pay attention to the apps that are being downloaded. Uninstall garbage and disable what you can't uninstall, but don't use. Hopefully this helps.
EDIT: Seems you fixed it. Nice! Well, use this as a reference for your next step if things don't stay behaved.

Clear cache and reboot. If you still have the problem, do a factory reset. Also, has the phone stabilized? Have you been through a couple of charge/use cycles? There could be a load of background processes setting up for the first day or so.
Seems the Qualcomm battery guru is a culprit as is the xfinity WiFi app.
Motorola said do a factory reset but I don't want to if something else can be done.
Think it's fixed by the WiFi location and the clean matter app showing the apps that kill the battery.
Here is a great article about asps that keep restarting in lollipop. It's a bug in ART. Google is working on a fix.

I'll post my battery drain/overheating story just to join the fray...i updated to Lollipop 4 days ago and I have had to charge my S5 at least a dozen times. I have tried power save mode, disabling every nonessential app and anything else I can find in the forums.
I used to get 15-16hrs of battery life (6am-10pm) with charge to spare, but immediately after the update my CPU sits maxed (monitored by Micro CPU Monitor) and constantly overheats (GSAM Battery Monitor). The phone went from 95°F to 105°F in 10min with standard use. I only had it overheat one other time in the last year (on my dash in the summer). I hope Google/Verizon will replace my battery because this abuse of it is going to shorten the life considerably!
See screen shots from the last charge at 4pm to now (10:15pm) all while UNUSED and in powersave mode plus battery at 107°F (a new record for me)!
I really don't want to reset the phone and lose my app settings, plus it seems to be hit/miss with other's issues. Any suggestions would be great.
Seems hit or miss.
Not sure what to tell you but try making sure you're Wi-Fi isn't always searching for locations when not connected. Seems this is a huge problem for many as Verizon threads and Android forums are filling up. I don't have an S5 but will keep looking for the fix.
Quick read-

Posted from my Moto X 2014
i am facing similar problem with my moto g2 if you find any solution please let me now
same problem to me also friend if u found any solution for it please mail to me [email protected]
I'm coming from the S3 and never had any problems with this, but on the S5 Pandora gives occasional hesitations (real quick skips) whenever I let it play with the screen off. It might happen 2 to 10 times per song, just depending. Sometimes I can go a while without it happening, but can't figure out anything that's different. It does not seem to depend on signal strength at all, as it happens in areas with good coverage. I thought maybe it has to do with the cpu being throttled down when the screen is off, but I'm not sure...but if so, I would think others would be having the same thing happen. Anyone have any ideas?
Uninstall app named 'adapt sound'
Or if you aren't rooted, just disable that app via the app manager. Please ask if you need further detail , I'll gladly assist.
I appreciate the suggestion, but after testing out quite a bit with "adapt sound" disabled, it seems like this isn't really making a difference.
I also should add that I'm usually streaming via an aux cable. After further testing, it seems that maaaybe toggling from the higher to lower quality audio makes a little bit of difference, but still doesn't eliminate the problem. Also, not sure why higher quality audio would be an issue given the strength of my LTE signal when this is happening...
Any other suggestions...
Are you not rooted/not willing to? I used a friends phone (not rooted) to test disabling adapt sound, they were having this same problem. Unfortunately disabling it didnt really change anything, to my surprise. I rooted the phone and fully uninstalled the app, and what do you know, the stuttering went away.
Now there could be a debate here about correlation vs causation, i have no clue how or why this happen(s). Just that it seemed to fix it for 2 phones ive personally dealt with.
I will find the discussion i previously read which singled out 'adapt sound' as culprit & see if there are other suggestions,
I cant believe no one else has anything to contribute
I am rooted but had tested your suggestion out by just disabling adapt sound from the application manager. I'll try completely uninstalling it though and test some more.
Another thing Pandora does is occasionally freeze upon opening after I've used it a few times since a reboot (it'll play, but everything in the app is frozen and the system will warn the app has become unresponsive). So I have to reboot to fix. With the stuttering and this, I had kind of decided Pandora just has problems running on 4.4.2.
Anyway, I'll report back after more testing, but would still welcome comments or suggestions.

I saw posted somewhere else that someone found out that if they turned off adblocking in luckupatcher it fixed it, so do you have luckypatcher with adblocking enabled or adaway? Give disabling that a shot if so and report back.
Sent from my SM-G900A using Tapatalk
I never was able to resolve the hesitations, despite having tried various combinations of disabling system apps like Adapt Sound and MusicFX. I also did not have any ad blocking installed. I was also having both Pandora and Spotify freeze and act wonky right after starting them up, which required a reboot to fix. That problem was more regular, and so I eventually narrowed it down to the fact that it would happen after every time I used the stock mobile hotspot. I was unable to resolve the issue any other way other than flashing back fresh to stock, rerooting, and reinstalling all my apps. Now everything seems to be working, and I think it may have resolved the occasional hesitations too - been listening a couple days and it hasn't been happening like it was before. Anyway, I went ahead and posted about the link between mobile hotspot and my issues with Pandora and Spotify here:

Hi, I've been trying to track down the issue with BetterBatteryStats+ and Wakelock Dectector FULL and found that the issue is with the bluetooth_pm wakelock. I've been googling about and people only mention it but nothing gets resolved. There's only one mention of it on XDA but no reply:
http://forum.xda-developers.com/showpost.php?p=63955981&postcount=29777
What makes it's annoying is that when it goes away randomly and I get to enjoy the damn Doze feature but only to have it come back randomly. And this is when bluetooth is on. I haven't not factory reset the phone and restarting the phone may or may not have temporarily fixed.
What's is the damn "bluetooth_pm" wakelock? There's not a lot of info on this wakelock and I can't use Amplify or DisableServices to reduce or get rid of outright. I hope someone has a solution this issue.
EDIT: It's a Kernel wakelock.
Sorry for bumping this again. I have still not found the reason of why it happens aside from disconnecting from my devices (I have my phone connected to my lg tone headphones, motorola headset, my car, and my android wear watch).
Is there a way to get into the kernel and just kill it manually or set a timeout setting to kill it. The only way for me to fix it is to restart my phone; I shouldn't have to restart to get rid of this annoying wakelock.
I really hope to hear a response soon. Thanks in advance.
Bumping one more time, now with logs if ANYONE is just willing to look into this and find out what's wrong: http://forum.xda-developers.com/showpost.php?p=66119017&postcount=30423
In this post attachment, it happened again just 15 minutes ago. Please, someone has to be technical to read the logs better than what I can come up to determine what's wrong with it or provide an app to find and kill this wakelock without having to restart the bloody phone.
I know this is super old but I found out that GasBuddy of all things was causing the damn bluetooth wakelock. Not a damn clue aside some saying it uses bluetooth for location but REALLY?
Luckily, using Greenify fixed the problem
I had the exact same symptoms and phone, did the same steps and found the same thing is as you. GasBuddy for some reason causing bluetooth wakelock. Greenify, as you experience, 'cured' the problem. Interestingly, after dealing with this issue for months, after only a few hours of verifying a fix, GasBuddy updated (with new logo) and while somewhat improved the wakelock issue, it's still an issue. Unfortunately, Greenify seems to have a more difficult time hibernating the new version...
This is kind of a big bump, but I'm having the bluetooth_pm wake lock on my G6 and Google doesn't show me much except for this thread. I don't have GasBuddy on my phone. Has anyone experienced the bluetooth_pm wakelock and figured out a way to get rid of it?

I am having same issue on my Verizon g6. I lose about 10% battery per hour when screen is off. Phone wake locks through the roof.
I seem to have been bitten by whatever it is that's causing Note 8s to freeze. In my case, it seems to freeze when idle - case closed, always-on display showing a clock. Sometimes the digital clock - just stopped; the last time, the analog clock with the second hand ticking, but an otherwise unresponsive phone.
It seems like this is happening to other people, in a variety of other applications - and the only advice anybody is giving is to see what happens in safe mode, then uninstall applications one-by-one. All of which seems rather time-consuming, and counter-intuitive -- if a single App is freezing the system, that suggests on o/s or hardware issue -- the o/s should be isolating the rest of the system from app misbehavior.
Which leads me to wonder how one might track down what's actually going on. If this were one of our servers, I'd crank up logging and look at crash logs. But... those options don't seem to be available without rooting the phone. (Why does Google insist on making syslogs unreadable by normal users - that puts a big crimp in the ability to do any kind of real trouble diagnosis.)
Any suggestions on how to do crash analysis? Any tools that someone can recommend?
Any insight on the matter?
I have not had this problem, so I would not know how to tackle all down to pinpoint the exact culprit, but I would start by controling what apps I dont want to run in background, in maintenance>battery>always sleeping, I put all the apps I dont need to be in always running state, I would also try to unistall or freeze apps I installed just before the problem began, if you have bk disabler this is a rather easy process, as you can batch-disable/enable apps, in the end it is a trial-error exercise
You can use logcat extreme, Catlog or somthing similiar from playstore. But you need some knowless to see wat happend and root. Perhaps you can pull the log file without root to your computer with ADB.
Sounds like impending motherboard failure. My wife's S7 Edge started doing the same thing then one day it just wouldn't start up at all.
Common thing for Samsung phones unfortunately .... and if you're out of warranty they won't repair without a charge.
