We hit 951 signatures, but i don´t think this petition get us to our goal, vivo is so restricted to security and ****, every time i had a conversation with the vivo support they ignore my wish and don´t listen to, i mentioned, release date of android 9, custom roms, source code and what not and they don´t answered, i mentioned i have problems with the notifications on my china vivo nex s and they mailed back a tutorial how to fix the problem. so i don´t think we get ever custom roms for this beautiful piece of tech at least not from vivo. maybe some skilled smartphone hacker get open the bootloader in the future? the security on this phone is strong. every Electronic device is hackable its a matter of time!
