About a month ago, my iphone 5s crashed. I managed to turn it back on, but it crashed again in a matter of minutes. The next time, as soon as it turned back on again, I deleted all my apps and photos thinking it was a storage issue... but it crashed again. I realized before this, I have been using a lot of data all at once since I was on vacation and sending my friends photos without WiFi. Could this have caused my phone to crash? Could anything else have caused this?
