Dear Friends as we know that Android is an Open Source OS so is the Kernel(Linux).Vivo Iqoo 3/7/9 are great devices having better hardware & software. But as we know that Vivo Iqoo doesn't provide bootloader unlocking & neither kernel source codes , so after 2-3 years these great devices will stop receiving official software/security updates. We want Vivo/Iqoo to provide Bootloader Unlocking method along with Kernel Sources so that 3rd party developers can develop custom roms which provides latest software support upto a long period of time .
