Why does my phone only go on apple logo
I have an iPhone 5s, and and a few months ago my apps started crashing but i thought it was because lack of space, and i can restart it and then it works again. Then just today, a few hours ago one of my apps crashed in middle of me using it and so i went to restart it, once i turned it off I pressed the power button to turn it back on and it only went to the apple logo screen for about 5-20 seconds then it turned off. I have been trying to turn it on but it keeps doing the same thing. It doesn't do anything once it is plugged into my computer or charging. No matter what I do it only goes to the apple logo screen then turns off. I can't update it, restore it or do anything. Is there a way to fix it? Or possibly get my pictures off of it. I have important pictures i can't loose.
