1) Rear Camera is good but Front is like 12 MP. I physically compared M51 and Redmi Note 9 Pro Max Selfie. Even in dark, Front Camera with Flash is very poor, just like 5 mp. Front image Clarity in Redmi Note 9 Pro Max is very good than M51.
2) 10x Zoom performance in Still and Video Camera is not good compared to Mi note 9 Pro Max.
3) Sometimes Quick Crop feature does not respond. After Restart, it is in normal.
4) Adaptive Brightness is not good. In Sunlight or Day light, Proximity Sensor function has a few bugs. While making calls in Sunlight, the Screen Display automatically off until double finger touches done.
Please Update in the above with some Extra Ordinary Camera features.
