[OnePlus 8 Questions & Answers] jiml8:
I am a brand new owner of a OP 8. First thing I did was flash it to OOS 11, then installed Magisk. The phone is now up and running and rooted.

I am coming from a galaxy S5 that I have owned and used for more than 7 years, and for most of that time it has been running Lineage OS. I am used to the control that Lineage gives me, and I would expect that I could exercise the same degree of control with a rooted OOS.

But, this appears to not be true.

On the S5, I had 3C System Tuner Pro which is now an obsolete app, so I have replaced it with the current variant; 3C All-In-One toolbox. This package should allow me to control which apps start at boot, but it seems I cannot turn any of the apps off; when I uncheck them, the app fails to actually remove them from the startup list.

Also, I expect the 3C tool to allow me to uninstall pretty much any app, but there are a lot of google apps that I just can't remove.

I also use greenify (the paid version) and mostly it seems to be working OK, except that I cannot seem to access system apps from it, which makes it very hard for me to shut down things that I don't want running.

I also use afwall (the paid version) and it seems to work as expected. Which is good.

My focus is security and privacy, and my mantra is: "on android, the app that is not running is the app that is not spying". Thus, I want everything that is not needed to satisfy my purposes to not be running, and I only want apps running when *I* say that they can run.

Now, my S5 was running Lineage 17.1 which is android 9. I did not update it past that. And now I am running android 11, and I note that there is a lot of new hardware-based validation in android 11. So possibly I can't remove some things without disabling this validation (which I would prefer not to do). But even if I can't remove, I can disable (which, fortunately, I AM able to do). But I should be able to remove things from the startup list so they don't get started automatically at boot time. Right now, the way it works is they all start, then greenify shuts them down (and that isn't always completely reliable). I need more to make this phone genuinely secure and private.

So.

Does anyone here know how I could gain the capability to remove apps (including system apps) from the startup list and have it stick? Does anyone know what I need to do to get greenify to recognize system apps so I can shut them down when they are not needed, or failing that, can anyone steer me to a different app than greenify that will do that?

Perhaps I would gain by adding the xposed framework? I have not used it in a very long time (since I move to lineage) and I recall it being a bit of a pain.

I suppose I could move to Lineage from OOS, but I would prefer to not do that because of the camera software. This device seems to have a fine camera and not a lot of bloatware, so I would much prefer to stay with OOS for as long as the device is supported by the manufacturer.

But I do insist on being able to completely control it, and disabling apps that I can't stop from running is a much bigger hammer than I would like to use; some of those apps I might actually want to use from time to time.
