There is no option to have the resolution changed to have rounded corners, personally i dont like it either, but you are only losing a tiny fraction of the screen at each corner which normally holds no information.yeah, but they are rounded to the point of cutting stuff off. is there no 3rd party thing i can do to fix this?
I would have prefered if it didnt take up so much screen real estate.
But for android, and every single app that you use seperately would need to be re programmed with a different aspect ratio with curved corners, and i doubt all those devs would change apps just to suit our phone.
The images you provided are clear examples thst you are losing literally no data with having the corners taken off. So except for accepting what you have there is nothing anyone else could do.
