I did a fun experiment once to confirm it’s not me sausage-fingering but the stupid iOS keyboard. There’s an app called xKeyboard which lets you design your own keyboard. I remade the FITALY[0] keyboard in it and even though the keys are slightly smaller than on the original iOS keyboard, I can type without making any error. Yet the iOS keyboard often detects the wrong key because of those stupid hitboxes. I wish there was a way to turn them off.
