Hello, First of all, yes I have looked at the forums and have found people with similar problems, but none actually got a good reply. A few days ago I noticed that my iPhones hardware volume buttons work perfectly when I have my headphones on, however, when I get them off, the buttons stop working and whenever I push any of them, I only get the overlay logo of the speaker/ringer but no bar is showed on the bottom. If I start the Music application, the same happens, no volume control is displayed and if I swipe on the taskbar twice to the left, the control isn't there either. It's clearly not a button hardware fault since I can use them with the headphones on, it's not a speaker problem because I get my calls ringing the speakers, so what could be? Any of you guys has had this issue before? Thanks in advance for any help that you can provide.
