iPhone: No Clicking Sound
Many long-time iPhone users are familiar with the mystery of disappearing keyboard clicking sounds (among other sound effects). Here are a few things you can try before you take your fruity phone back to the store:
1. If you are a proud owner of iPhone 3G, make sure the silent switch was not engaged by accident. This tiny knob was placed by some idiot near the volume control buttons to make it more convenient for your to activate it unintentionally. The primary purpose of this silent switch is to make you miss important phone calls.
2. Take a can of compressed air and clean the headphone jack. If this doesn’t help, plug and unplug the headphones repeatedly a few times to remove whatever may be stuck in the jack.
3. Did your iPhone stop making sounds after you installed a new application? Uninstall it, why don’t you? Especially if this application is using the buggy “push” update feature.
4. Reset your iPhone by going into Settings -> General -> Reset -> Reset All Settings. Your contacts, notes and apps will not be harmed. The icons will be rearranged to the factory default, your ring tones will be reset, and you will have to re-enter your Wi-Fi password.
5. If all else fails, back up your iPhone and take it to the store. Did you see the part about backing it up first? Just checking.
