After receiving its necessary certification from China's telecommunications regulatory board TENAA last December, the Xiaomi Redmi Note 4X has been officially unveiled in China which is similar to the Redmi Note 3 device in terms of design. A Hatsune Miku Limited Edition Redmi Note 4X is also introduced in limited quantities, which will be available in Valentine's Day.

Earlier, the Xiaomi Redmi Note 4X visited telecom regulatory board for its certifications, which revealed its key specs and features. After being official, Redmi Note 4X contains similar screen display like the Redmi Note 4 smartphone's 5.5-inch screen.

The Xiaomi Redmi Note 4X is also sticking with its original camera sensors and battery unit, Indian Express reported. It will sport a 13-megapixel primary rear camera, as well as a 5-megapixel front-snapper. The device will also house a hefty 4100mAh battery. As of now, Xiaomi has disclosed few details on the Redmi Note 4X's design and chassis.

In terms of the Redmi Note 4X's internal unit, Xiaomi fueled the smartphone with Qualcomm's Snapdragon 625 octa-core processor. No additional information was revealed as opposed to possible two CPUs coming in different countries, which is employed in the Redmi Note 4. To those uninitiated, Redmi Note 4 came with a MediaTek Helio X20 deca-core SoC in China, while the Indian market received a Snapdragon 625 variant of Redmi Note 4.

Xiaomi has not yet confirmed the RAM and storage options on the Redmi Note 4X, although previous leaks point to 3GB RAM/32GB storage, 4GB RAM/32GB storage and 4GB RAM/64GB storage. The device may leave out the original Redmi Note 4's 2GB RAM option.

All in all, the Redmi Note 4X will not be an upgraded version of its original handset in terms of hardware. However, the new device seems to cater a cosmetic upgrade through a customized package containing a printed protective case and a limited edition Mi Power bank.

On another note, Xiaomi introduced a special variant of Redmi Note 4X, which is the Hatsune Miku Special Edition, NDTV reported. The phone will start selling on Valentine's Day and will pack the same tech as the Indian variant of the Redmi Note 4. The Redmi Note 4X Hatsune Miku Special Edition offers several color variants, namely Green and Cherry Pink colour variants. Aside from that, the Redmi Note 4X will also be available in Champagne Gold, Matte Black, Cherry Powder, and Platinum Silver Grey colour variants.

Xiaomi did not reveal the pricing details for the Redmi Note 4X, but confirmed its availability on Feb. 14.
