This works on my EVO 3D, but I assume that it will work on any phone with sense 3.0+. That means like most htc phones out now.
There’s actually three ways of doing this, just muting the ringer without rejecting the call:
- Press Power button once, pressing it one more time will reject the call.
- Press VOL UP or VOL DOWN once.
- Placing phone face down on a flat surface, if it’s already face down it will still ring. You need to then turn it over and again place it face down to silence it.
Was looking for something else, and found this instead. The last one I knew about, but not the first two. Pretty handy things to know.
