Despite carrying a glass-fronted gadget in my pocket for most of the past two decades, this is the first time I’ve done this:
Turns out you can’t trust a rolling seat on a slightly unlevel surface, as shifting your weight can let the thing roll out from under you with no warning. If you’re taking a picture at the same time, the phone reaches the impact point before your hand: even a nice case with bumpers all around won’t be quite enough protection.
I was tempted to leave it un-fixed as a constant reminder to not do that again, but the broken glass was rough to the touch and interfered with Android’s swipe-upward gestures.
Fortunately, the tempered-glass screen protector absorbed the energy without damage to the actual screen:
A thin plastic layer holds the protector’s fragments together; I hadn’t known it was a two-layer structure.
Being that type of guy, I had a spare protector in a desk drawer and managed to apply it without trapping any bubbles or fuzz underneath.
