Is Xiaomi Redmi 2 truly 64-bit ? Seller says so My Phone was sold to me as 64-bit architecture, but the Apps like device control, show that it is actually 32-bit. What is correct?

And if anything is wrong,  how should I proceed?
Redmi 2 has a Chipset that supports 64-bit but the Bootloader is not 64-bit ready.  

Technically the seller didn't lie as the device is 64-bit architecture but you cannot install a 64-bit ROM (yet) since the bootloader is not 64-bit ready.
