So a year ago when my S9 started doing this, I read something that said to disable Google. The only thing I really noticed I was missing was the ability to use voice features. Not a big deal for me, but some of you may really miss that. I would rather have timely notifications than voice to text, etc. I did it and it worked. I was hoping this would not effect my S10 but after 3 weeks, my new phone started doing the delay too. I was hoping to find a new fix so started following this board and tried everything that was suggested over the last 2 months. Nothing worked for me. So I disable Google again and it worked for me again, notification were coming in on time. Just to check I enabled it and notifications over the next 24 hrs began to delay more and more and apps wouldn't download right away. So I disabled it again and its been good for the last week. Again, you will loose the voice features (OK Google, voice to text, etc) on your phone. If you want to try it, in your apps, find or from your apps screen search for google. Locate the large colorful G and in your apps menu hold it down until you get the small pop up menu. There should be an option to disable. Thats it, the app disappears from your app list but notifications and downloads work again. If you want to re-enable the app, to to Play Store and search for Google. It should be the first one, big colorful G. You can enable it from there. Hope it works for you if you try it.

I dealt with this for 11 months with the S9 and never figured out a fix. Got the S10+ in March and the S10 just started doing it. I can't deal with this for another year, I hope they figure out a fix real soon!!
