My Iphone 4s shuts apps down randomly and won't let me save pictures or take screen shots?

My facebook, instagram, safari and even photo apps all shut down at random times. When I tap on them again, they pop up for a split second and turn off. I can't screen shot or take pictures and none of my pictures taken via instagram are saved to my phone like they used to be. Sometimes, Insta won't even let me upload photos from my camera (yes, I checked all of my privacy settings and its all enabled for sharing). I'm starting to have trouble sending texts as well. I tried restarting and rebooting the phone. It fixes the issue for about an hour, if that. I have no storage left to update and can't delete anything else… I went on a deleting spree and only have a handful of apps left. I have never had a problem with my Iphone until now. Please help! About to throw the phone at a wall, lol.

More then likely you don't have any room on your device. You have to check your memory. If it says 0 bytes you may have to delete a couple songs that you don't really want or a lot of unnecessary photos/videos to free up your phone.
Go to: Settings>General>Usage. Then look to see how many bytes of free memory there's. If it says 0 then walla! Time to delete.
The tricky part is even if you delete a couple it may not pop up in the free bytes that you have freed up any bytes but just know that as long as you delete some stuff to make room there should be that much room. Deleting apps doesn't really work that well but photos and songs work a lot better. This should work, try it and ket me know how it goes!
If not then more then likely your going to have to delete that app and download it again or get a new phone.
