Hi people of Blackview forum. I'm from Brazil and i own a Blackview Alife P1 Pro for abouth 2 months. My previous device was a Samsung Galaxy S5, a week after my warranty expired the motherboard just died, that's why i though this time i would buy a unknow branded device.
Currently my Blackview is my second device, that's because i bought a ZUK Z1 too at the very same time. I'm very satisfield with both devices and i'm impressed with so many updates on my Blackview, that's great cause i hate when companies stop developing and caring for old devices (even though this isn't that old), it's a must nowadays, that's why i recommend and would buy future Blackview releases.
Anyway, about the topic here, the only bug i found so far is that sometimes the screen wouldn't unlock with fingerprint scanner, it seems as it doesn't activate (read) at all, so i power off and power on the screen and it would work so.
Ah, as it's my second device, i'm not a heavy user, but as far as i tested i have no issue with mic volume. The last ota upgrade was kinda tricky, as i had to reboot the phone twice to screen icons appear, but now everything works as it should.
Keep the good work Blackview, thanks!
