Delayed notifications issue affecting all range of Samsung devices since at least half a year.

First Poster

Hello,

 

Introduction:

 

Currently ALL newer flagship models are affected by delayed notification issue for at least past 6+ months,  which started happening after around may 2018. Most devices are affected such as: S7, S8, S9, Note 9 and similar.

This is related to "doze" feature of android phone, where samsung optimization whitelist options are not working correctly thus affecting almost all samsung phones.

 

The issue  is reproduced during following scenario:

 

1. User locks phone, waits around 5m

2. App sends notification (which is not marked as PRIORITY in google push services).

3. User does not get notification

4. User unlocks phone, and suddenly multiple "delayed" notifications arrive.

 

Multiple users has reported the issue and tried various workarounds such as:

 

- Disabling battery optimization for certain apps

- Disabling all battery optimization options

- Making sure "WIFI" connection is always maintaned, even during sleep mode

- Making sure DATA connection is always maintaned

- Restoring device to factory

- Totally replacing devices with new ones.

- Wiping cache and similar

 

There is currently only one temporarly solution working, which is disabling doze using adb console. This workaround is temporarly and works until next reboot. It requires setting phone to debug mode and connecting to it.

 

"adb shell dumpsys deviceidle disable"

 

Samsung reaction:

 

Samsung is totally ignoring the technical issue since at least 6 months or more. There are multiple threads all over the web about such problem existing. Examples:

Implications:

 

The issue is making phone totally unusuable for people who rely on instant notifications, such as alerts related to financial services like declining stock rates and similar. I dont understand why such critical thing like delivering notifications in time is totally ignored by samsung. The issue is not present on any other android phones.

 

Request:

 

If you have ability to contact someone of samsung development team, please forward this thread to make sure there will be finally reaction. Please reply to this thread if you have same issue.

So that notifications can come through.  I might go as far as researching what it means to root a phone and auto-run that script on start-up, because I LOVE getting my notifications right away.  This is how life should be!


keep in mind that if you root, you will trip knox. Once knox is tripped, you won't be able to use secure folder anymore.

Thanks!  That sounds like a great Pro Tip.  I'll research all the dangers of what sounds like a drastic step.

I run that command every time I reboot my S9 but my Gmail inbox is still delayed at times.  Everything else seems to work fine without delay.

Bob, do you have a way that's easier than USB and command line?  Or you do it the hard way?  Maybe you don't shut it down at night like I do...

I reboot the phone rarely so it works for me.  Run CMD prompt, copy and paste the command and good to go.  I always have access to a  windows PC both at work and home.

I just wanted to give everyone a heads up that the fix I previously mentioned (shutting off the Dynamic Lock features on my Windows 10 work laptop and the Bluetooth) is still working great for me. It's amazing; it's like a whole different phone. I now drive basically everything through the "Your Phone" Microsoft built-in app and my smartwatch. I love it. 

 

I hope everyone else finds out how to fix their devices because it is a seriously annoying issue that really must be universally fixed.

Hi, QA Analyst Weisenbarger.  I was certainly interested in that and jealous of you for finding a solution, but I don't use the Bluetooth on my phone.  It could be the Wifi on mine, I suppose.  I know I read that some people had better luck turning Wifi off.  I may try that after I eventually restart and lose my adb idle disable.

are you saying you have to turn off bluetooth as well? or just disable dynamic lock?

I'm not sure if turning off Bluetooth as well as dynamic lock is necessary but I did both and since it's working I just left it. I might try later on turning Bluetooth back on but leaving dynamic lock off.
