The main difference from the base Redmi 10 was the processor and the main camera. If the regular Redmi 10 received a 50 MP sensor, the version of the “S” got a 64 MP module with improved detail, and the “S” version lacked an ultra-wide angle camera at 8 MP, giving way to 2 MP macro shooting, which was criticized by many.

Compared to the Samsung Galaxy A52, which also came out in the spring of 2021, the Redmi 10S won in trim (charger in the box) and price, but lost in water protection (lack of full IP67 in the global version of Redmi, although in some regions IP53 was claimed) and long-term support for updates.
