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

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:

 

1. https://us.community.samsung.com/t5/Galaxy-S8-Questions-and-Answers/Delayed-notifications/td-p/11494...

2. https://forums.androidcentral.com/samsung-galaxy-note-9/911157-push-notification-delay-when-screen-o...

6. https://forums.androidcentral.com/samsung-galaxy-note-9/906887-delays-notifications.html

 

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.

I have the same issue on my samsung S9. This is critical to me because I have monitoring application which send notifications if something is wrong. My previous phone samsung S4 is working normally. Samsung, pls, fix this ASAP, or I'll have to sell this and bay some other brand which is working properly.

I have a Samsung s9+ and am having the issue when my phone is screen locked eg phone on but screen off.

When off many notifications do not come through but the minute i turn on the screen they come through.

My phone is on the latest software.

Any ideas on how to fix?

My provider is Woolworths mobile which back bones off the Telstra network.

 

Thanks

Anyone having the issues on non-Samsung Android devices?  My Chuwi tablet behaves the same way so I am suspecting it may be Android related.  My Ipad displays all notifcations instantly!

Just got my S9 a few days ago and I have had the same issues. Thanks for the (temporary) fix. It blows my mind that I dropped so much money on a phone and they can't even fix a simple bug for 6 months. I've sent a message to Support about it, hopefully they get it to the dev team, because this is actually pathetic for a flagship phone.

Look at the end of the first post, basically you gotta enable USB debug mode and use abd to insert a command which disable power saving or "doze" mode.


As for me, I'm probably returning this phone.
