iPhone 4 ear speaker issues
I am using an iPhone 4 and I've recently upgraded to the most recent software update in hopes that the speaker issue will be solved (iOS 7.1.2).
When I am using the ear speaker (making any calls/receiving calls, facetime audio etc.) the sound is extremely muffled to no sound. The speakerphone works perfectly. If this is a software issue how do I correct for it? I want to downgrade if this software is not compatible with my phone. I've had the speaker work at times before but recently it has not gone back to normal. So I am not sure if the ear speaker is damaged or if this is software issues?
Any help is appreciated.
