You know the Oppo A77 that was announced in Taiwan on May 17? Well, there's a new one, as evidenced by two new entries on Chinese telecom regulator TENAA's website. Those detail an A77 and A77t, neither looking visually the same as the existing A77, plus there are notable differences in specs.
For starters, this new A77 runs on the latest Android 7.1.1 as opposed to 6.0 Marshmallow. TENAA doesn't name chipsets, but the octa-core processor is quoted to be clocked at 2.0GHz, where the existing model's clock frequency is 1.5GHz. So it isn't the MT6750T then, but something along the lines of a Helio P10 or a Snapdragon 625, maybe.
Other changes include a 3,115mAh battery (vs. 3,200mAh), a minor drop in weight to 148g (vs. 153g), and slightly different dimensions at 153.3 x 75.9 x 7.4mm (vs. 153.3 x 75.2 x 7.2mm). Oh, and a redesign that puts the camera and flash under the same window to resemble the dual camera setup of the R11, plus a familiar take on the antenna bands.
Things that remain unchanged include the 13MP primary cam and the 16MP selfie shooter. The new A77 also sports the same 5.5-inch FullHD LCD.
By the looks of it, the A77 certified by TENAA is the version destined for Mainland China, which apparently differs slightly from the one Taiwan is getting. It remains to be seen when it's going to become official.
