HTC One X camera has secret Bluetooth controls
Here’s a clever trick for those of you who want to take pictures with the HTC One X while not actually touching the shutter button yourself: it turns out there are hidden Bluetooth controls included in Sense 4.0 that will allow you to operate the camera by pressing certain button combinations with Bluetooth headsets.
Here’s the catch: this unofficial, undocumented feature works differently with different headsets. So, for example, you have to tap the volume up button twice on an iTech brand A2DP headset, while Jabra and Plantronics Bluetooth headsets require you to triple-tap the dial button. On the other hand, some headsets (like the Motorola Finiti) don’t seem to have any button combination that activates the shutter, so this is definitely a case of YMMV.
Some have implied that this may work on other HTC One Series devices, or on a device like the HTC EVO 4G LTE, but I haven’t been able to confirm this myself (I actually don’t use Bluetooth headsets, but that’s another story for another day). In any case, this seems like a fantastic little feature – definitely one that HTC should refine and start bragging about.[ePrice via Android Community]
