So far, every time you rooted your Samsung phone, you would trip Knox, making everything Knox related useless, like Secure Folder, Samsung Pay, etc. Now, the new fingerprint scanner is also located in Knox, which if we go by the previous experience, if you trip Knox by rooting your phone, you'll end up with a useless fingerprint scanner. Now, this won't bother you who don't root, but I like using apps like AdAway to completely remove adds even in apps. And the reason why I choose Android is that I like the customization offered. I will hold onto my Note8 as long as I can, but I hope there will be some good alternatives in 2020.
