difficulty in detecting multi touch

In my game hero jumps when the player tap both fingers on the screen.

I use Input.touchCount to find whether it is a single tap or 2 finger tap.

The game works fine with this but I found out lot of players have difficulty in tapping at the same time. Even when the player do a two finger tap the game detect it as a single finger tap.

If I could increase the time unity takes to decide a tap in “Input” this might be solved. Is there a way to do this?

Or is there another workaround for this?

Thank you for your help.

I’m fairly new to C# and not completely familiar with all of it’s limitations, but perhaps you could set up your own detection by creating a variable that updates after a certain amount of time has passed, perhaps a quarter of a second, and if another press has happened before that update has happened, it registers it as a multi-touch.
