About Oppo A77
The Oppo A77 presents a straightforward mid-range package centered around a 5.5-inch TN-TFT LCD screen running at Full HD resolution. Its slim 7.4 mm profile and 148 g weight keep it light in the hand, while the 75.9 mm width ensures a comfortable grip for one-handed use.
Inside, the phone pairs Android 7.1 Nougat with 4 GB of RAM, aiming for smooth everyday performance. A 3200 mAh battery provides the juice, and despite the Dual SIM label in its catalog name, this specific configuration supports a single SIM card.
This variant stands out with its Color IPS TFT LCD display, which replaces the TN-TFT panel of the base model, though it drops the resolution to 720x1280. It also runs an older Android 5.1.1 Lollipop instead of Nougat.
The design is slightly tweaked, with dimensions of 76 x 154.5 x 7.38 mm and a weight of 160 g, making it marginally wider and heavier than the base model. Unlike the base model, it retains a single SIM configuration but is marketed as the F1s 2017 in some regions.
