If you are thinking about trying iOS 13 Public Beta 2 (17A5522g), don’t. Developer beta 3/public beta 2 is usually a point when things settle down and come into focus. Not this time. The first iOS 13 developer beta 3 build (17A5522f) was almost solid enough to recommend. After installing yesterday’s seemingly minor ‘g’ build release, my iPhone XS mini-reboots itself more than 10 times a day: whatever I am in the middle of, the screen goes dark, the refresh icons twirls, 5~10 seconds later I’m looking at the lock screen.
Unless you are really horny, don’t screw around with the iOS 13 betas, all of them. Wait for the official release, or better yet the first point release.
