Iphone ringer and volume bar not working?

A few days ago I dropped my iPhone 4s in a sink of water. My otterbox case helped protect it so i don't think much water got in but my ringer and volume is not working. I can't listen to music unless i plug headphones / speakers into it. I tried cleaning the dock connector with a toothbrush multiple times but no good.

Go to
Settings> General> Accessibility> Assistive Touch. Turn it on gives you a button on touch screen in case your home, lock, or volume buttons don't work

  • Why is the ringer sound on my iPhone not working? My ringer sounds are suddenly not working on my iPhone 4S. All of the other sounds are working fine, but the keyboard clicks, lock sound, and notification sounds are not working. I notice that when I try to turn up the volume of the ringer, I get a blank screen like the attached photo. Does anyone know how I can fix this? Thank you!
  • Why does the volume bar on my iphone disappear and appear whenever it wants to? I have an iPhone 4. If I try and listen to music the volume bar goes away and when I try to adjust the volume with the + and - buttons the volume bar under "ringer" is gone. I've tried restarting my phone, fixing the settings, plugging in my earphones and cleaning where you plug them in and connecting my phone to my laptop but nothing seems to work.
  • Volume bar and sound on iPhone 4s? When I'm playing music on my iPhone the volume bar disappeares and there's no sound. Everything else works perfectly, it rings etc just music and media it won't make any sound. Any ideas?
  • Volume bar on my iPhone 4 has disappeared? My volume bar has disappeared on my iPhone 4 when I play music through the speakers. I can't hear the typing of my keyboard either, but when I go into voice memos I can listen to them. After that I go into my music library and play music and the volume bar is there for about 5 second and disappears again. I have tried rebooting it and it's done nothing. The sound will just come and go. What the hell is wrong with my iPhone? Please and thank you. P.s it isn't jail broken either.
