Hi, i use the Kishi with my s20 fe 5g. your s10 5g is a bit bigger. compare the two devices. i think your device is pretty much the maximum that fits. otherwise ROG also has a controller for the ROG Phone that is compatible and a bit bigger. i don't know your device exactly, but the usb c port has to be in the middle of the device. otherwise it won't work.
greetings
