This happened due to the change in Aspect Ratio in the latest devices. Smartphones went from 16:9 to 18:9 and 19.5:9 which changes the ratio drastically. On iOS this is taken care with Launch Images, but on Android you have to specify the max_aspect.
This started with Galaxy s8 where max_aspect was 2.1 (18:9) and then raised to 2.16 (19.5:9) with pixel, op, new galaxys etc.
There is also a new Sony xperia where max_aspect should be 2.3, but tnh no one cares about Sony anymore 😛
