Toggle button sometimes not triggered by touch on some mobile devices.

I'm on unity 2018.1.0f2. I have standard toggle buttons that work perfectly in the editor on desktop. They also work 99% of the time on my Android Pixel XL phone, but they only work half the time on a Samsung Note 8 I was testing on. I noticed that touching the toggle on the Samsung phone will trigger the Pressed Color, but wont actually trigger the toggle about half the time.

Has anybody else inexperience inconsistent button/toggle on mobile devices? And can point me in the right direction to fix this issue?
