If you werent already impressed with Redmi Note 7s 48MP camera maybe Night mode will change your mind. This update was announced on MIUIs official Weibo page and will be released later (with no further clarification).
The Redmi Note 7 is the first of its siblings to feature the large 1/2 ISOCELL GM1 sensor with 48MP resolution. Individual pixels measure 0.8m, but they can be binned to simulate a 12MP sensor with 1.6m pixels.
Xiaomi included four sample shots with the new mode and they are indeed in 12MP resolution.

So far only Xiaomis premium devices have night mode. Mi Mix 3, Mi Mix 2S and Mi 8 have already received it, the Pocophone F1 is set to get it in February. And none of them have a 48MP senor.
