How to open my iphone settings?

Just recently, I opened my settings on my iphone and it would only open for a few seconds before closing again. All my other apps works fine and Apple is not helping. So any other suggestions?

Try turning the phone off and see if it helps if not then another option is to get it looked at

Some apps where doing this to me as well, try deleting some memory like messages, unwanted, apps or photos. If the doesn't work you can try the Genius Bar

Try powering it down and powering it back up. (hold the top right button down until the power down prompt comes up).

If that doesn't help try connecting it to whatever PC w/iTunes you sync it with, do a restore.

edit---

Before doing a restore try killing all running applications. You do that by doing a quick double click on the button on the front of the iPhone. You will get a pop-up with all your running apps along the bottom. Hold your finger on one of the apps until they all start to jiggle, then one by one tap the red - button on each app. You should do this periodically. IThings do weird things when they start running out of memory. When you leave apps running they suck up memory.

Delete some of the apps you don't use because your phone memory might be full
