Static sound coming from earphones!!

I've been experiencing a few weird problems with my

iPhone 5 lately! It all started when I begun getting messages that my phone doesn't support this kind of device (my charger).

Then my home button stopped working all together for about 12 hours, which I really panicked about, and then suddenly started working again.

And now when I if my earphones in all I hear is static sounds!! It is so frustrating as I use it so much for car audio through aux and earphones. You literally cannot even hear a person speak it is pure static noise! There is probably

No fix for this, and my phone is under the 1 year warranty, so can I get this fixed?
