Camera won't take photos whilst on apps?
Whenever I'm on either Facebook, Tumblr, Twitter, WhatsApp, Instagram or even sometimes just the camera app itself, and I go take a photo to put upload straight away (i.e. taking a photo whilst on Twitter rather than uploading from my camera roll), it freezes for 2 or 3 seconds and then just shuts the app down - even sometimes (especially on Instagram and Twitter) doing the same thing when I just try and upload from the camera roll. Can anyone tell me why this is happening and what I can do to fix it? Thanks.
iPhone 4S, iOS 6.1.4
