My step-dad is the same way. He breaks things and it's never, at any point, his fault. They just spontaneously break! My family quit helping him and quit paying for things and he eventually either figures out how to use it properly, or has to buy new ones for himself.
Tell your parents not to buy anything like that for her anymore, and if she breaks it she can figure out how to fix it herself or pay someone else to do. I don't believe she's too stupid. I was using computers and all sorts of electronics when I was a little kid and I never broke anything, mostly because I knew my family wouldn't have the money to fix or replace it. It ended up working out great for me because I was trusted with a lot of cool new stuff that other parents wouldn't bring close to their own kids (a Game Boy, our family's DVD player). Meanwhile I knew lots of other kids that deliberately destroyed their electronics because they knew their parents would get them a new one when they started crying about it. When she starts seeing that every time she breaks something it's gone forever, she'll start paying more attention to what the hell she's doing.
ah the tech plague i don't let my sister touch any piece of valuable tech for the error occur it is a waste of munny to have to replace over and over again. but i don't think she's doing it one purpose so here whatcha do.
fix her phone but do it at your leisure be as complex as possible
for music on android create folder named music on SDcard place music there boom music
make it know that it hers she break it she better google how to fix it oh don't for get to do a good job fixing so you can say "you whine I no fix good day to you sir" add the sir it just pisses em and hold her to it when he comes for help.
now on the off chance that she is breaking on purpose get proof then expose and she will have a flip phone till she gets a job and buys her own >:}
