It turns out the HTC One X has a secret hiding in the HTC Sense 4.0 overlay to ICS. Certain Bluetooth headsets can actually control the smartphone's camera.
A Bluetooth headset can be used as a remote-shutter for the One X, by pressing a combination of buttons on the headset itself.
No one has confirmed if there is anything that details this in the HTC documentation, so it is possible that this 'remote control' will work with other HTC One smartphones too - such as the One S, One V or the recently leaked, Desire C.
For an iTech A2DP headset, users need to double press the volume up button, whilst owners of Jabra and Plantronic Bluetooth headsets need to triple press the dial button.
The HTC One X promises "lightning-fast web browsing, remarkable picture quality and seamless gaming visuals" due to its quad-core 1.5GHz processor and a 4.7in screen.
The smartphone features 1GB of RAM, 32GB of storage and weighs 130 grams. The device also boasts an eight-megapixel camera and 1080p HD video recording, and runs Android 'Ice Cream Sandwich' 4.0.
Earlier this week, HTC recognised a bug in the X's message notification system, and has promised a solution. The issue affects users as they are not notified of a new message, when the phone receives it and the counter badge on the messaging icon also fails to update.
