vivo is a Chinese technology company that designs, develops, and manufactures smartphones, smartphone accessories, software, and online services. It was founded in 2009 in Dongguan, Guangdong, China. The brand uses Hi-Fi chips in its smartphones.
Software developed by the company includes the Vivo App Store, iManager, and a proprietary Android-based operating system called Funtouch OS. It's a custom fork of Android but nothing is perfect. Funtouch OS has it's own cons, no Android updates to phones except security patches.
And more over users needs choices, you cant just get stuck with just Funtouch OS right .
Due to unavailability of kernel sources we third party developers couldn't build any custom aftermarket ROM's.
We request Vivo to please release complete Kernel sources so we could build great aftermarket firmwares .
Vivo is currently voilating GPL because the Android Kernel which is just a linux Kernel is licensed under GPL .
You make Great Phones but locking down to Funtouch OS doesn't let us (users) to get full potential of the hardware .
You claim kernel sources are closed for security reasons knowing that the linux kernel is todays most secure kernel because it's open source, so why not listen to your users voices and release kernel sources .

Vivo Y51L Users.
