Instagram app wont open on iphone?

[Osi]

The instagram app will not open I have a iphone 4s. It was working at first but something messed up then when i tried to open it again it just closed after 3 seconds. I have tried to reinstall it plenty of times and still fails to work.

your phone is damage some how. restore and it should work fine

try turning your phone on and off a couple off times. i dont know if 4s has this but hold down the home button as if you were going to delet stuff. then duoble click the home button. tap the red minus button on every app that is there. i hope that works!
