IPhone 4 can't hear callers?

Ok so I've had my phone a little under a year. Every now and then the speaker will stop working and I won't be able to hear anything when I call people. I would usually just clean the speakers and restart it and it would work again. Now nothing I've tried can fix it. I cleaned the speakers checked the headphone jack restarted the phone. What can I do. I'm so annoyed with this phone

Is it insured or under warranty? Maybe you should take it to the apple store and see what they say

  • Why can't can't I hear anything on iPhone 4s? So everything is on in the sound option and it isn't set in vibration it's in sound also, the only method I can hear videos or anything is if I plug in the headphones how can I fix it I've tried turning it off and on already but it isn't any better.
  • When i call someone on my iphone they can't hear me and i can't hear them why? Well it just happened i was calling my dad like 10 minuets ago and then i hung up and then called him 5 minuets later and i could hear him but he can't hear me for some reason why is that? I'm sorry i meant i CAN hear them but they can't hear me
  • Recieving text messages from unknown callers? Simply saying, "Hey." it has happened a few times in the past as well. My phone is an iphone and is fairly new from last December if that helps. So who are these people? Is it safe to open the message so long as you don't reply? I accidently went to the message, and hope that no one is currently hacking my phone.
  • My callers ID picture don't show wide on the scream in my iPhone 5s. What should I do? I have an iPhone 5s and I need help I want my callers I'd to be shown wide on the screen. Their pictures don't show wide on screen they are just small pics. I want big pictures in the whole screen! How can I do that?
