i'm with the others who think the mi10 camera is pretty good. what you said about "focus on middle and rest of image is just bad", well that's bokeh. REAL OPTICAL BOKEH, not processed/faked ones: something that's not possible with smaller sensors on phones typically, and approaching what you can get with much larger dedicated cameras. It's not a fault, but an achievement, IMHO.
What might have also impressed you the wrong way is probably the characteristic cold tones of the Samsung sensors compared to the much warmer (lab tested pleasing) tones of the Sony sensors. Though Samsung sensors would typically appear sharper overall even with comparable resolution, never mind between mi9 and 10. Sharpness and resolution should be hands down in mi 10's favor. Getting GCam should help a lot with dynamic range issues in difficult lighting (you seem to have unfavorable/difficult lightings for both of the Mi10 samples compared to the mi9, which were both shot with much better lighting conditions).
