Monitor Feedback from the iOS 12 Beta
If you don't have plans to try the iOS 12 beta on your iPhone, iPad, or iPod touch, make sure you follow the iOS 12 beta for important feedback about bugs, features, and overall performance.
As the iOS 12 update goes through testing, those testing the software will uncover potential benefits and problems. This feedback could help you make a decision about whether to download iOS 12 on day one or stay on iOS 11 for awhile longer.
The good news is that we've seen a steady stream of feedback emerge in the weeks since the beta's release in June.
There are plenty of places to read about iOS 12's performance, but this post over on MacRumors forums is a great place to start.
Each beta will be a little bit different so make sure you dig in every time Apple releases a new beta.
