Your mirror has the most accurate representation of you because it is a mere light reflection inverted laterally. But phone cameras have different resolution and pixels, meaning the image you view is a processed image instead of a real-time representation. So if your camera sucks, it's because it's old. Plus, you need to have a good angle. አገጭህ ስር ከከተትከው አገጫም ያረጋል፣ ግምባርህ ላይ ከሰቀልከው ግምባራም ያረጋል። So don't worry. If your phone camera sucks, it just means you're broke 😁. That's what I tell myself 😭 Hope this helped. Good Day!
