My snapchat won't send anything and it crashes. How do I fix?

I have a jailbroken iPhone 4. Snapchat works fine but whenever I try to send a snapchat, the app crashes and closes. I deleted and downloaded it again about 50 times, still doesn't work. Same problem happened to my Instagram a while ago but it was resolved by Resetting the network setting and re downloading it. I also tried that but still doesn't work. Can someone help me?

Your phones probably just overheated. Turn it off for like 2 minutes. Then try again

My snap chat does the same have you worked out how to fix it?

  • My snapchat won't let me record and send videos? So I have an iPhone 4s, and I recently got the update in which you can send videos to friends. The problem is that my phone won't record a video. I know that you are supposed to press and hold the camera button, but whenever I do that, the screen just turns black and there's no video recorded. I can receive videos just fine, I'm just having problems taking the video. Also, I've tried deleting and then redownloading the app.
