I have had that problem too! My 16GB iPhone 5S suddenly become black screen when i using it, and do not have any responds untill after it finished restart automatically. At first, i though it might caused by a certain app, but i delete the apps, and my iPhone still continue to become black screen. At last, i tried a software and delete all the junk files and temporary files, and get about 5GB free storage for my iPhone. Now it work normally now, i can't make sure the problem fixed by getting enough free storage or clearing up junk files. Anymore, you can both of them.
