Are you running Android in your device? Maybe you could give https://doc.e.foundation/devices/jfltexx/ a try if you want a more private experience.
Not sure how /e/ is supposed to be more private yet less open?
I'm using my i9506 (ks01lte) as a daily driver, though I think I'll switch to a i9505 because it has official lineageos support, which means probably less weird SD card bugs.
I wish I could install it on my mi a1
I am not sure how much work that would be to maintain it yourself on your particular phone, but it might not be that much? I don't really know, though.
