The Xiaomi Mi MIX 2S flagship will be announced on March 27, and some new camera info has just surfaced. Before we start talking about that, it's worth noting that this new info was found in the leaked firmware of the Mi MIX 2S, just like some previous info that was published by the same source. According to this new info, the Xiaomi Mi MIX 2S will feature a portrait mode, and the same goes for a multi-frame noise reduction (MFNR), and slow-motion fullHD video at 120fps.
The Xiaomi Mi MIX 2 did not feature any variant of a portrait mode, but it seems like its successor will. The 'portrait mode' reference was found in the MIUI Camera APK, as a method that checks for whether or not the feature is enabled was spotted. The phone's leaked firmware also references multi-frame noise reduction, also known as MFNR, a feature thanks to which multiple photos are taken in rapid succession, and then post-processed (superimposed), so that noise gets reduced in a final image that is produced. MFNR is actually available as part of the Qualcomm Spectra 280 ISP, which is included in Qualcomm's Snapdragon 845 SoC, which will fuel the Xiaomi Mi MIX 2S, that much had been confirmed already. MFNR will be available in Xiaomi's MIUI Camera, though, it seems. Having said that, the Xiaomi Mi MIX 2 does offer slow-motion video capture, it can capture 720p video at 120fps, and it seems like Xiaomi will bump that up to fullHD at 120fps, according to some references found in the MIUI Camera APK.
The Xiaomi Mi MIX 2S will also be able to encode videos in HEVC, while 'parallel processing' and 'dual SAT camera' were also referenced in the firmware, but it is still not clear what that means. The Xiaomi Mi MIX 2S will sport really thin bezels, and it will probably ship with a 6-inch OLED display, at least if the earlier info is to be believed. It is possible that Xiaomi may introduce two variants of the phone, a more affordable model which will be made out of metal and glass, and a ceramic unibody variant. 6GB and 8GB RAM models are also a possibility, at least if the Xiaomi Mi MIX 2 is any indication.
