Safe to install iOS 9 public beta on primary device?

Not sure if this is the same thing that happened to me. When I received a phone call the other day rather than my usual ringtone it was a horrible crackling sound, similar to when a tv channel hasn't been tuned in. Only happened the once.

Yes! This is exactly what happened to me. Hasn't happened again though, thankfully. Well, a few more days and we will get proper iOS 9. Hopefully nothing will explode before that :tongue:
