I wouldn’t trust Forbes’ reporting about iOS.
The article you mentioned is titled “Apple iOS 11.3.1 Release: It's The Big One.” There is no 11.3.1, not yet, not even in beta. The author is just speculating.
The author of these iOS-bashing Forbes pieces is kind of an iOS troll. Every time a new version of iOS comes out, the guy scans online forums, compiles a list of people’s problems, and then posts on article in Forbes about how awful the iOS version is and how Apple had better release an update to fix it. He treats each forum user’s reported problem as a legitimate issue with iOS that will plague everyone who installs this version on their iDevices; he doesn’t consider the possibility that someone’s complaint is due to something other than iOS, like user error or a rogue app.
What he doesn’t tell you is that the vast majority of users are having a positive experience. Few people post an item titled “Wow, another smooth iOS version! How great is this, guys?” People generally post only when they have problems, so they can get help from other forum users. So if you count positive and negative posts about a new iOS, the negative ones will always far outnumber the positive ones.
I’m not blindly loyal to iOS, nor blindly opposed to Android. But it doesn’t help anyone when either OS is unfairly bashed, by a supposedly respectable publication like Forbes, or anyone else.
