UPDATE: As many of our readers reported, this trick does not actually work. Also, HTC contacted us to say that its engineering team could not replicate the issue and determined that the ROM used in the video is not stock.

HTC One M9 owners beware – the pattern lock on your phone is very, very easy to bypass, even on the latest version. The trick is dead simple:

1) Use the Quick toggles on the lock screen to toggle Wi-Fi (on or off, doesn’t matter) 2) Done

Did you expect more steps? Well, there aren’t any. For whatever reason the HTC One M9 just skips over the pattern lock when the state of the Wi-Fi changes. When it disconnects, it unlocks the screen. When it connects to a network, it unlocks the screen.

If you have an M9, please try this method and report in the comments whether it works (including the ROM version).
