Is your phone under warranty?
I think at times we have all been scared of our parents. It depends to what extent as to whether it is abusive or not.
Whether people agree or disagree, a lot of parents use physical discipline with their kids. Has your dad ever hit you before? Is it that he gets really angry when you've done something? My mom would get very angry at me at times as a kid, I was definitely scared of stepping out of line and that wasn't a bad thing. I remember breaking my new touch screen phone when I was 16 and she wasn't best pleased having to get me another.
Only you know your situation, would he normally get so mad at you over something that was an accident?
If your mom is the calmer of the two, could you maybe talk to her on your own?

Oh and I was saying about the warranty, with things like Apple phones I know they come with 12 months free and you can take your phone to them. Not sure how it works with accidents and things like that. I took my phone to them when the headphone thing broke and they just replaced the phone. That's assuming you've got an Apple phone. But I'm sure other models would also carry a warranty, maybe worth having a look?
