The Mi Mix 2s will probably feature a much improved rear camera setup than its predecessor. Further, Xiaomi has teased many AI features to be on the device as well in the past week. However, some firmware files handed over to XDA have unearthed some great camera features. Below is the list found from the firmware.
The Mi Mix 2s will come with a Portrait mode. As the device will have dual rear shooters, it will also be able to take portrait shots. The Mi Mix 2 did not have this feature. The MIUI Camera APK which was torn down showed clear evidence of the feature.
The Mi Mix 2s will also get 1080p at 120fps slow-mo feature. The Mi Mix 2 also had the feature but that was at 720p.
Multi-Frame Noise Reduction is like a burst mode. It takes many photos in single instances and presents a picture with reduced noise. This feature is part of the Snapdragon 845 chip that has Qualcomm Spectra 280 ISP.
The auto scene recognition feature was also found to be present in the APK teardown.
Looking at these features, the Mi Mix 2s will definitely be upping its camera game by some levels. However, the actual performance will only be judged when the actual device is seen in action. For a more detailed look at the teardown, visit the XDA link here.
