As stated on other threads beta OS/iOS versions are designed to use consumers as test subjects. There will be issues with some devices even with the public beta releases because they are new and manufacturers cannot test every possible variation of use.
Apple's suggestion is, try it and if it doesn't work let us know.
Ideally, as per Apple's suggestions, you should not run even a public beta os on your Primary device. I always used a Partition, External HD or second iPhone/iPad for this purpose.
If you use your primary device you run the risk of loss of function or in the worst case scenario loss of private data. Even with an opt out option and a full backup you will certainly experience a lot of inconvenience.
