iPhone 4 - Speaker volume too low
I bought yesterday an iPhone 4.
Today, while activating, I noticed that the speaker didn't make a sound (ringtones, keyboard, lock, iPod...), while everything worked fine with headphones in.
I already tried to restore many times, and no result.
Later, I noticed that keeping the iPhone speaker very close to my ear, I can barely hear the sounds (again, ringtones, keyboard etc.). Anyway, this is not helpful, as I can't normally hear those sounds.
Is this an hardware or software issue? Does anyone know how to fix that? I already planned to go to Genius Bar, but due to many issues I have in the meanwhile, it would be very cool to be able to solve by myself. 🙂
