It’s more of a personal one.

I made my first touch game in Unity. I tested all the system and everything worked after weeks of testing and I wasn’t able to find more bugs.

I gave my phone to my wife and asked her to try it. Immediately she was able to get the character to warp across the screen. I didn’t code this and based on my code this was impossible to happen.

After more testing I discovered that it wasn’t my code which was bugged but Unity’s. Since she was touching the screen in a way that it didn’t register that her finger was removed from the screen.

Ever since all my games touch inputs have manual timers to ensure that a touch is actually registered. And I give her my games to test since she usually breaks it in weird and wonderful ways.
