Multiple presses needed to enter pin

[SalmanShami]

I have a problem with my Ionic. When I need to enter the pin number I need to press one of the digits multiple times before it registers.

It is always the third number in the sequence. 

* * _ _ 

After about the third press it adds the number in the register

* * * _

The number is highlighted on the numberpad, which shows that the screen has registered my touch. However, the number is not registered.

I've noticed that if the finger slips to much during the key oresd, the key may not be inputted.

The number on the numberpad lights up so the finger press is registered but it does not add the number to the array.
