  1. Hi Dhananjay, yep tried both disabling power saving mode and removing google from the special access optimized list 🙁

    1. Do one thing. Remove Google Play Services and Google app both from the battery optimization list. Then clear Google App data. Finally, restart and check again. Thoroughly tested on my friend’s Note 8.

  2. Okay I think I fixed the issue with the Note 8.
    On the Note 8 you have to go to a different place to remove Google from the optimization process.
    1. Go to Settings
    2. Select Apps
    3. Click on the three dot menu drop down.
    4. Select “Special Access”
    5. Select “Optimize Battery Usage”
    6. Scroll down and deselect Google.
    I also deslected all that start with “Google”
    As well as “OK Google Enrollment”
    It did not seem to work immediately, so I wiped system cache… That didn’t seem to have an immediate effect, however, now a few hours later it’s working just fine.
    I can go into Bixby, come out and say OK Google and it works every time.
    I have no idea what difference waiting a while did, but everything is working well now.

    1. Thank you, Roald for sharing this with us. Very much appreciated. I will update the Method 1 steps according to your solution. I hope it will prove more useful to the Note 8 users 🙂 Thanks again.

  3. What he means is that Google doesn’t appear in the lists of appa to add or remove from monitoring on the Note 8…so it can’t be excluded or included in the settings for battery optimization.

    1. Thank you, Roald. If Google App is not available in the unmonitored apps list, then you may try disabling Power Saving mode. The problem occurs when the Note 8 battery optimization/power saving mode restricts the Google app from working in the background.
