Icon not visible on Samsung s10 and similar

Icon not visible

Hi
In my app, icon is not visible on some higher resolution phones having Premium Galaxy (fHD WQHD),Premium Galaxy (QXGA),Tablet Galaxy (WQXGA WXGA) . What should app icon size in pixels ? I used 512×512 on this app . This doesn’t work, so tell me should I use 2560px icon or something to give a lead .
