We take a look first at the difference of design. On the front, both UMIDIGI S3 Pro and Redmi Note 7 Pro feature the 6.3’’ FHD+ waterdrop display, but we can clearly see the UMIDIGI S3 Pro got a smaller chin. And the S3 Pro sports a ceramic body while the Note 7 Pro has the glass one. About the frame, UMIDIGI S3 Pro’s frame is glossy metal but Redmi Note 7 Pro’s is just plastic.
It turns out a better dynamic range and contrast on UMIDIGI S3 Pro, also a more natural image color. Redmi Note 7 Pro’s photo is also decent but we note a slight bias towards the red side of the white balance spectrum on the Redmi Note 7 Pro. Also the contrast between shadows and highlights is not that obvious on the Note 7 Pro.
In the 48MP mode, the photo is brighter on UMIDIGI S3 Pro with less noise when in dim light. In terms of sharpness, when zoom in the photo, the details are a bit blurred on Redmi Note 7 Pro while we can see more details on UMIDIGI S3 Pro and the sharpness is more consistent across the frame.
UMIDIGI S3 Pro and Redmi Note 7 Pro both obtain dual camera setup. Besides the 48MP Sony IMX586 primary lens, UMIDIGI S3 Pro sports a 12MP telephoto lens offering 2x optical zoom and bokeh effect, while Redmi Note 7 Pro has a 5MP depth lens only providing bokeh effect.
The UMIDIGI S3 Pro has a better camera performance than Redmi Note 7 Pro in the US$270 price range due to its excellent image quality and great image details. And the UMIDIGI S3 Pro will receive an important update at the end of May or the start of June. The update will include camera performance optimized and new features added like night mode and beauty mode, so we can expect a further optimized performance on UMIDIGI S3 Pro. Plus the overall design like high screen-to-body ratio and ceramic body, UMIDIGI S3 Pro is no doubt a good mid-range camera phone under US$300.
