In the last two months, YU, in its bid to build buzz around Yutopia launch, has been targeting rivals OnePlus and Apple.

The Indian company mocked their devices for having flagship tag and yet lacking some key features like long battery life, high storage capacity and others.

In the latest teaser, YU has taken a swing at the world's reigning smartphone leader Samsung. The company has posted Samsung Galaxy S6 Edge series phone and criticised the device's UI TouchWiz, which does not allow customisation.

The screen-shot of the Galaxy S6 Edge phone's display reads -- "Warning!! This customization is not supported".  Meanwhile, YU has promised that Yutopia will allow numerous personalisation options hinting that the marquee phone will run on Cyanogen OS.

[Note: Cyanogen (Mod) OS is the most popular aftermarket ROM in the world having more than 12 million subscribers.]

The news comes close on the heels of YU's new AOSP (Android Open Source Project) 6.0 Marshmallow challenge inviting developers to create ROM for its devices. This apparently led many to believe that the company's association with Cyanogen might have ended.
