I definitely would not pay for their OS's (mobile or desktop).
Its a minor, bug-fix update that benefits iPhone X users who encountered issues after acquiring the new phone just under two weeks ago. On the other hand, I kept trying iOS 13.1 with iPhone 11 Pro Max and iPhone 8 devices, but both get stuck after some loading. Except the fact that I’m staying on 11.01 (which seems to be running pretty good so far) until a jailbreak is released. Apple released iOS 11.1.2 for iPhones and iPads this afternoon. iOS 11. Apple security documents reference vulnerabilities by CVE-ID when possible. I tried starting new devices and an iPhone 6s on iOS 12.2 loaded successfully on the first try. You can encrypt communications with Apple using the Apple Product Security PGP Key. It is free, so I guess we can't complain. In the Simulator, I also tried to 'Erase All Contents and Settings', quite a few times, to no avail.
all devices conncected seemlessly in iOS10 and before.
Been a problem for 4 iterations of iOS 11 and hasn't been fixed. I have multiple bluetooth products that will only connect to the iPhone and show up in Apps if I reboot the phone. I won't go into the terrible bluetooth interface that seems to plague every single iOS release. But people are already looking forward to the next incremental, non-bug-fixing release. If you can't follow your own GUI rules for development, then I don't have much confidence in their ability to release a software product that functions as it is intended. Following a somewhat problematic initial release of iOS, Apple pushed out iOS 11.0.2 to fix a number of issues. I have not been impressed with Apple's ability to release polished software for many years now, and I still am not impressed after iOS 11 with all the GUI problems and bugs that are all over the place.
I have some days when I have full bars but Safari tells me I am not connected to a network. My cellular coverage has been odd since 11 came out.
After manually overwriting and installing phone data again, switching into airplane mode, resetting network connections, and rebooting the device, I have full LTE coverage in the same spot that was giving me only 3G coverage this morning. Sprint had me manually upload all Sprint data again and overwrite the FW upload request I received 13 hours after updating my iOS to 11.1 which was odd. They have to deal with the interface as well. That is why carriers are rolling out Firmware updates for the cellular connections.
