After flashing Magisk, you try to download "Boot animation" from Google play and then try install a new boot animation. If it ask you to accept SU permission, that your phone rooted. Because Root checker told me the same thing.
After flash EU rom, i can't turn on 4k in Open Camera. And EIS didn't work well like china stable rom 9.6.7. Any solutions for this? I really want to stay on MIUI 10.
Sorry for my bad English.
