The latest iOS 9 figures posted to Apple’s developer site show that adoption is currently stalled at 77%, the same number reported at the last update earlier this month, but still ahead of the iOS 8 curve. iOS 8 took until 18th March to hit that same 77%.
Most of the hold-outs are running iOS 8, at 17% of the total while only 6% are running an earlier version. This contrasts strongly with Android, where a miniscule 1.2% of devices are running the latest 6.0 Marshmallow flavor and the greatest number are still on 4.4 KitKat.
Apple yesterday released iOS 9.3 public beta 4 with Night Shift, Touch ID Notes, & Verizon Wi-Fi Calling.
