Pick two. Or, if you’re feeling less charitable toward Apple, one.
"Just today: My iPhone 6 rebooted after I changed the home screen wallpaper. Tapped a new image in the wallpaper settings, and poof, it rebooted. Worse, it never stopped rebooting. Endless reboot cycle. Now I’m doing a full restore with iTunes. After changing my wallpaper to a different image."
(of course, anyone who buys brand-new Apple designs on launch day is playing with fire in a fireworks factory…)
(not that anyone else’s first shipment of new stuff is necessarily glitch-free, but Apple does seem to be particularly bad at it sometimes)
Update: I followed the link from the article I linked, and while reading it… Safari crashed.
