My iPhone X got stolen from my pocket a couple of months ago. I switched back to my iPhone 5. Last weekend an acquaintance of mine jokingly put my iPhone 5 out of my pocket and I immediately felt the little pressure of having a phone on your pocket going away so I was able to recover my phone. Even though it was a joke, now I'm actually very afraid of investing in a new phone because right now I don't think I'm able to stop someone from pickpocketing me in a crowded place anymore.
I was wondering if someone has a solution to this problem? I need some kind of notification when someone tries to pickpocket my phone and/or a way to lock my phone in my pocket.
