I get one mi sports Bluetooth headset, but when I use, the sound is not the best, and I'm on miui 8.3, 7.4.20, and I can't find a equalizer... Then I try to install viper4android with biohazard, but it need busy box, and busy box need root, then for could continue use Pokemon Go, I try Magisk v12 and Magisk Manager 4.3.1. But nothing work. . The driver of viper not get installed and screw my calls, no body could listen me or I can listen none... And Pokemon didn't work.... Safety net never pass ok, even after reinstalling miui 8.3 for delete viper... Any ideas?
