My speaker on my iPhone 4S won't work

I've had this iPhone 2 weeks now I got it of eBay but its a company who sells them and its newly refurbished! I was on ft to my friend and I couldn't even here what she was saying. I played music and it seems funny, what's wrong? It was never like this before and I never dropped it or sat it near water

My mom had the same problem on her iphone 4s, the speaker wouldn't work so she took it to the apple store and they couldn't fix it so they gave her a new one for free!

  • Why won't my iphone 4 speaker work? I dropped my phone into water and I put it in rice and its dry and it works perfectly but whenever I go on YouTube or play music the speakers won't work but for headphones it works and when I'm in speaker phone it works please tell me what the problem is thanks.
  • What do i do when my iphone 4s speaker won't work? I recently went on a trip to a lake and my phone got wet and now my speaker won't work. There's no sound. I noticed in the headphone jack that the "water" sensor had turned red. What do i do?
  • Water in speaker iphone won't work? Just now i spilt water on my pone but i rubbed it all off as soon as it happened and i think some got in my headphone bit! Now my phone thinks i've got headphones in when i don't and i don't know what to do? I can't tell my mum shell kill me!
  • My iphone speaker won't work? So my iphone's volume bar won't show up whenever i click on the side volume buttons. And i think it might be from water. I used a "waterproof" iphone case and took some nice underwater pictures but when i took off the case water had gotten in. Is there any way to fix the problem I have tried restarting, cleaning the headphone jack and the charging area, using a hairdryer and putting it in airplane mode.
