Comparing the designs of OPPO A77s and OPPO A77, we notice that these two versions do not differ significantly. Both feature a modern design with slimness, lightweight feel, and ease of handling and operation.
The bezels of both models are thinner, although the bottom bezel is slightly thicker compared to the other three edges. Additionally, they both have a waterdrop notch design for the screen and rounded corners. Even the color options remain the same with black and blue variants.

2. Screen Quality Comparison between OPPO A77s and OPPO A77

According to Benchmark tests, the Snapdragon 680 scores about 100,000 points lower than the Dimensity. Through real-world experience, the OPPO A77 demonstrates better multitasking capabilities than the OPPO A77s. Especially in heavy graphics gaming challenges, the OPPO A77 experiences less lag compared to the OPPO A77s.
Furthermore, they differ in memory configurations. The OPPO A77 offers two memory options: 4GB RAM + 64GB ROM and 6GB RAM + 128GB ROM.
