My iPhone 4S' music is scrolling by itself?

After I added music onto my iPhone from my laptop, I opened the music app and when I tried to scroll, it was very lagging(?).It started jumping to random letters in the song selecting bar and it chose random songs but it won't actually play them, it just skips right through them all at random. Is there any way I can fix this without restoring my WHOLE iPhone?

Added (1). Question (user): I have turned it off and on a few times in hope that it'd change, but it continues to skip around.

Are there any other apps that are affected? If so you might have the first stages of water damage. People think you need to drop your phone in a toilet to have water damage but you don't. If you work out with your phone in your pocket, listen to music while in the shower, etc those are just a couple examples. Even talking on the phone while seating can create condensation.
So I'd back your phone up and then restore, if the problem persists then try a water damage treatment… Sucks but I've been there…

  • Why is my new iPhone 8 freezing the music on the lock screen and turning the volume up and down itself? When I'm listening to music and then click home to light up the screen to change a song or whatever the song will be almost over and it'll say it's at 0:30 seconds? And then when I go to Instagram it just turns the volume up and down without me pressing any volume buttons?
  • Updating iOS version on iPhone itself? Hi, I was wondering if I updated my iPhone to the latest version, on the iPhone itself; i.e, not going through iTunes, but rather by settings>update, will I lose my photos, contacts! And will I lose my jailbreak!
  • My iPhone turns itself on and off randomly? My iPhone 3GS has just started turning its self off and on like 20minutes ago and it's got 57% of battery left, I don't know what's wrong? And I don't wanna go to the apple shop because I don't want my mum to have to pay for a new one because we have a tight budget. And if I tell her she will go mad!
  • My iphone's screen will not turn on, but the iphone itself is still on? I have tried holding in the home and top button, I know that the iphone is on because when i press the buttons i can hear the little click noises. It is fully charged, and i have not been able to get it up in itunes, but i can access the music on it through another program. Does anyone have any suggestions on how to resolve this issue? I do not want to take it in to the store unless absolutely necessary.
