Ear speaker on iPhone 4 suddenly very low, near mute.
My iPhone 4 is a 16 GB, about a half-year old.
I have replaced the front screen. Everything went smoothly, and the new screen worked like a charm. But after three weeks or so, the ear speaker suddenly became extremely low—at normal volume levels, it's impossible to detect any sound.
So now I'm stuck talking with the speaker on or using a headset. Which is not too cool...
I have done the works, as far as I know, for the software. I've done a hard restart and used iTunes to reset the phone to original settings.
None of these attempts have worked, though. I´m not that technically advanced when it comes to electronics. So I am just wondering if any of you could give any tips how I should fix it.
Is it a hardware error or a software problem? The speaker works. I can turn it up and down with the volume buttons, but it's all extremely low—essentially useless. Is there some software error that may have dialed the whole volume setting down somehow?
It's probably a hardware error, and my Apple guarantee is no longer valid, as I have changed the front screen. Should I try to replace the ear speaker myself, or should admit defeat and pay a pro to do it?
I hope you guys have some good ideas!
Is this a good question?
