Especially, as designers think it’s cool to have tiny buttons on the touch screen.
Touchscreens don't provide this. If your finger comes into contact in the wrong place, the wrong thing happens. So your first contact must be absolutely correct.
Your arm is extended. Your hand/finger partially blocks your view of the button. Your depth perception of that flat plane with fluid reference points is not good. Bang! The wrong app completely opens.
Now you have to spend time dealing with the consequences of that your error, even if you don't feel inclided to try again. Instead of rewinding to re-listen to the last 20 seconds of a podcast because traffic demanded your attention, you are now listening to the radio and have set an alarm for midnight.
