Android L Developer Preview Ported to HTC One M7

Google Upcoming OS, Android L developer Preview was released for some of the Nexus flagship devices like Nexus 7, Nexus 5 and Nexus 4. Anticipations were that the next release will be either for Galaxy S4 GPe, or any other GPe edition device, but no one ever thought that it will be released for HTC One M7, however unlike as ported to the Nexus devices, we can say that the Alpha version was released for the Official devices.
