Galaxy A52 does not display "True RGB". Red on A52 shows up as orange, even my old J2 Pro has much better colours. The problem is also with green and blue shades but those are less noticeable, I have also compared it's display against One Plus 9, my color calibrated monitor and my laptop, all of them display red more accurately than A52. I also tried changing the colour temperature in Vivid mode (Advanced Settings) but it didn't help. I really don't understand if it's a software issue on calibration or they used cheap Amoled panel, in any case it's a real shame.
It's a Dell monitor, don't exactly remember the model. I checked using calibration chart it seems way off from red, if you wish to check just put it against any display which shows true red or even just red. Open any "Red Background Image" on both A52 and the display you want to compare against. A52 display will show "Orange" which is more of Red-orange.
