By Carrie Murray, Friday, June 29, 2018

You can now download and install iOS 12 public beta on iPhone, iPad via Apple's Beta Software Program. I myself have installed iOS 12 beta on my iPhone 6 yesterday and it works like a charm!

As you may have known, the main focus of iOS 12 is performance improvement. And based on my experience with my iPhone 6, I would have to say Apple has done a wonderful job this time. After updating to iOS 12, my old iPhone 6 runs significantly smoother, the apps load faster and I haven't noticed any bugs, battery or memory issues that were found in iOS 11 last year.

If you have a spare iPhone and would like to have a try of Apple's new features like group FaceTime, Screen Time, follow these steps to download and install iOS 12 public beta right now. The following steps are recommended by Apple and can protect your iPhone/iPad from data loss or other iOS update problems to the maximum extent possible

If you have tried it and don't like it, you may uninstall iOS 12 and downgrade to iOS 11 any time.
