Oppo is apparently gearing up to release the much-awaited R9 smartphone. It is believed to be the successor of the Oppo R7, released in 2015.

As it turns out, the Chinese tech titan has advertised the launch of its Oppo R9 by posting a slew of ads across China in subways and bus stations. Going by the ad, Oppo will take the wraps of the R9 on Mar. 17.

Oppo has been featuring mid-to-high-end configurations in its smartphones. However, this time around, the Oppo R9 is believed to come with top-of-the-shelf specifications and a killer exterior design rumored to resemble the Apple iPhone 6s Plus.

Gizmo China said this handset will be marketed as Oppo's high-end camera phone. Plus, Oppo is known for housing excellent battery units along with futuristic charging technology. With the R9, the company is expected to maintain that standard by housing the newly introduced Super VOOC rapid charging feature.

As far as the rumored Oppo R9 specifications go, GSM Arena said that the handset will feature a humongous 6.0-inch display, packed with a QHD screen resolution. Under the hood, it is believed to come powered by Qualcomm’s Snapdragon 820 SoC, seen in the recently introduced LG G5, Samsung Galaxy S7 series and the Xiaomi Mi 5.

When it comes to camera configuration, the Oppo R9 will apparently sport a killer 21-megapixel rear-facing sensor. In addition, a very-generous 13-megapixel front-facing snapper for selfies and video chats has also been tipped.

This device is expected to come backed by either 3 GB or 4 GB of RAM. Not to forget, Oppo has been very generous with RAM configurations so far. Plus, the R9 will reportedly come equipped with 64 GB of built-in storage space with microSD card slot on board to facilitate expansion.

A phenomenal 3,700 mAh battery will apparently keep the lights on. On the software end, without any surprise, Android 6.0 Marshmallow OS will run the device out of the box.

In any case, readers should note that, Oppo has not confirmed the R9 specifications thus far.
