Why does my iPhone only work on speaker but not regular?

If I receive a phone call (the ringer works) I can only hear the caller if it's on speaker. Also if I play a song (music or YouTube) it doesn't play out loud, but I see the little equalizer thinkers going.

You have fuzz or belly button lint caught in the speaker. You can try to blow it our, or use canned air to give it a squirt.

Call Verizon or take a visit there. They should be able to fix it for free, or tell you it's defective.

Check the other sound volume sliders to make sure that the ringer, media an system sounds volumes are all up.

  • Why isn't my Iphone (5) taking regular pictures and only able to take Selfies? When I take a picture of the object in front, the screen goes blank and the picture doesn't get taken. It then slides to the start page. When I start the camera it goes on flip mode automatically and only takes selfies. any idea what's the problem here?
  • Why does only one speaker work when I connect my iphone to my Hi Fi system? I brought a brand new Hi Fi system today, tested in the shop with my iPhone connected and it worked fine, both speakers working.

  • Why does only one speaker on my iPhone 4 work? My boyfriend has the same phone as me only he has not had it as long as me. When we play music on his phone both speakers work. But on mine the left one doesn't work. I have never damaged my phone. Always had a protective case on it. I'm very easy on it. What's wrong with mine? Could it have been messed up from the start? Or is there a thing I can change the setting. I checked the music In the settings and the speaker thing is in the middle.
