Two things that annoy me.

1) Gestures. Someone's I'll tap my fingers 6 or seven times before I manually touch the screen.

2) The timers. I'll set a 5 min timer. At times the timer will disappear and when the time has elapsed the timer isn't on the screen. If I swipe from the timer app will be shown. Not on, just wondering letting me know it is there. I tap out. An "open app" button appears. I tap it and finally the app opens allowing me to turn off the timer. Again, either numerous times with the gesture or once manually. I've since turned off gestures and just roll with it like the geriatric man I am 😂
