The following text completely freezes the reciever's iPhone, causing it to be nearly unusable. The only way to fix it is by force rebooting but the freeze may persist after the reboot. It also hasnt been picked up by any news outlets yet from what I've seen.
I've only tested this for about 5 minutes and got it to freeze someone's iPhone through an iMessage text banner notification. The reciever was on iOS 13.1.1
If you are able to find any more uses or ways to get it to freeze the reciever, please comment below and I'll edit the post accordingly.
After another test it seems like the freeze may only work if those are the only characters in the message.
Sending it to a snapchat groupchat makes everyone's snapchats crash when they load it.
thanks alot ur amazing
