What does my Bff want on my cell phone?

I slept with my best friend yesterday and I plugged my cell phone into her room and every damn time she just took my cell phone out and made slowmo videos because I have an iphone and she was a Huawei. I thought I was just doing the same thing but as soon as I got close to her cellphone she quickly picked it up and said, "Let my cellphone". It just annoyed that she could take my cellphone but I couldn't hers. I told her Let me have my cell phone too, I can't take yours either "but she does it anyway. What should I do?

Oh, every time she unplugged it, she threw it around and I don't think that's ok…

Lock your phone with a code or something similar.

You have worries

Ka I have on Iphone just have to swipe left to open the camera

Are not worries. Only it is my cell phone and why should she be allowed on my cell phone but I shouldn't be on her

Then put your cell phone under your pillow and make an announcement

You're right. I think I will change anyway.
