I have this problem too.

But my apps dont close immediately after the screen locks. They start closing a few hours after they have last been used.

If I go to bed with 20 apps open, I will wake up 6 hours later to only 2 or 3 left open and running.

Keep missing notifications

If Duraspeed is the "toolbox" icon in the recent apps pane, then I've already gone what you suggested (I saw the whitelist as a suggestion in the BV9800 forums and thought to try it). Whitelisting didn't work for me.

In the same 'Settings > Smart assist' menu, there might be an 'Auto clean memory' option. turn it off and mark the apps you need running in background, just in case.
In the 'Settings > Battery' menu there might be a 'Standby intelligent power saving' option. If the fix above doesn't work, try this too...

I have the same issue. This causes so many problems in my life because I don't receive notifications from so many different applications. I don't see any "smart assist" option in my settings, nor is it there when I search for it. Not only that, but I haven't been able to use my samsung active2 watch since updating to android 10. I have posted here about it, and blackview told me to write to them on their website. I wrote to them and they gave me a three word response. I am very frustrated and dissatisfied with my experience.

Where is smart assist in the settings? I don't see it

I don't have smart assist in my settings. Please help me, blackview

How do I find duraspeed? It's not in my settings

9900 Pro

I am on android 10

I own a Blackview BV9900E running Android 10 and can't find Dudaspeed to disable apps' killing.
It probably affects Vanced Tube and kills this app after the screen is locked for more or less 5 minutes.
Some methods of accessing Duraspeed described by other colleagues in this thread don't work on Android 10.

@Blackview Team - how can we enter Dudaspeed options on Android 10?
Thanks.

Right. That's what I have been saying. How do I do this on Android 10? I have a Samsung Active2 watch that I haven't been able to use since the OTA update. I also don't get notifications from many essential apps. I my have to sell the phone because blackview refuses to help solve these problems. I have been on this forum for MONTHS dealing with these issues. Absolute nightmare
