IPhone messages app crashes when opened?

Someone sent me a text that would turn off my iPhone somehow and now every time I try to open the messages app it crashes.

I just had this happen to a friend of mine and troubleshooted. If it is from a single person, send a photo to them through the Photos app. If it is from a group, you need to have someone in the group delete you from the conversation and then re-add you. This is NOT affecting all devices so you may be able to see the corrupting string of characters yourself. If someone keeps sending it to you, block their number through Settings -> Messages -> Blocked.
