I got a Redmi Note 9 a year ago in January. I was so disappointed about the MediaTek chipset and its limitations. No 60 fps video recording (real bottle-neck), 0% custom recovery/ROM support, and a waste of time unlocking the bootloader. I had to even send the phone to the service as it got bricked while updating from the MIUI 12.0.5 to 12.0.9. And of course, I didn't have anything backed up (including my 70GBs of photos and videos from my summer vacation). I'm even afraid that I won't sell the phone as it is "old". I heard that it should get the Android 12 and MIUI 13, but I highly doubt it. The whole phone was just a HUGE failure as a starter or a Redmi Note 9 series. I would say the 9S is just a downgrade of some features, but with a Qualcomm chipset at least. The Pro, the best of the best. Even if the battery is a bit smaller, it has to drain much slower if the phone is running on a custom ROM. No MIUIDoesn't work on mine... Every step is done, but it opens seems to work fine, but then I want to switch the mode or press on record. Boom, hung up! Could it be, because the Redmi Note 9 has a MediaTek Chip and not a Snapdragon chip? I've heard, that the MediaTek chips are more problematic than the Snapdragon one's. Because Xiaomi.eu-ROM doesn't work aswell, because it's MediaTek. But I don't know...
