If you have a iPhone or iPad that you are not dependent on, you might want to try out the public beta of iOS 13 or iPadOS. All you have to do is enroll in the Apple Beta Software Program. It is easy. Open the link below and follow the instructions. I recommend first making a backup of your device with iTunes.
Be aware that there are bugs in beta software. Do not install beta software on devices that you are dependent on to work.
