[RACHEL]

ok so I was helping my mom clean at work and well my phone dropped in the bucket . no need to tell me how stupid or clumsy I was, I am well aware of that. what I want to know is how to tell if is the battery or the phone itself. So it works..but it goes directly to camera -.- and I can make calls but when I try to end it the volume setting thing goes up and down like the phones is possessed so yea I just want to know is it the phone? or battery. I have no insurance so I am desperate. so desperate I put the phone and parts in rice because I looked it up on the internet. lmao DON'TJUDGE ME!! HAHA. just answer my question..plz? thanks
