Alright, so I know some of you have seen this already but if you send this message: effective Power لُلُصّبُلُلصّبُررً ॣ ॣh ॣ ॣ 冗 To another iPhone user then it will shut off the phone automatically. It's super annoying because all my friends send it to me it's just really annoying. Just thought I'd share this :p
If you cut out a certain part of the text it makes it so that every time they open iMessage, it crashes. The way to get rid of the constant crashing is to send them a photo from the photos app.
