It has told you what to do. "The camera also doesn't work on it, it says that too many applications are running and to close them down before trying the camera again" I believe it is telling you that you have used too much of the memory with apps you have installed and/or have running so it fails. Try uninstalling one or more apps that you do not use frequently and see if that makes a difference. Phones/tablets/PDAs, etc. need a certain minimum amount of free memory to operate. Older devices have less memory than newer ones and the operating system is subject to constant bloat, as well as users constantly installing apps (and seldom removing unused ones) so the free memory constantly shrinks. When those devices no longer have enough free memory they display symptoms similar to what you describe. I hope this helps.
