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.

Transferring iphone pictures to sd card?

So i recently went to a concert and i wanted to put the pictures/videos on an sd card. I have over 5000 photos in my camera roll so instead of importing ther few videos to my computer i just plugged in my phone, inserted the sd card and copied/pasted (on the computer is says move to new location but same thing) the photos by having two libraries open. I need to clear up space on my phone and id like to know if the photos are actually on the sd card, since i just copied and pasted them. Please help because i barely have any storage on my phone and i would be devastated if i lost all my concert videos

Will the iphone 4s work better and faster if I buy 32gb opposed to 16gb?

Will the iphone 4s work better and faster if I buy 32gb opposed to 16gb. I'm so indesissive which one to buy. I usually don't keep more than 500 photos. Which one has better battery life? Which one is faster? Adding more money for one is no problem. Which one works better? Wouldnt 32 gb be faster since your limited with the 16gb and when your almost filled of space for photos it works alot slower? What is your opinion?
