[Bug 1364412] [NEW] unity8 freezes after pocket touches

 

Public bug reported:

I have a mako running the rtm branch and I use a PIN. If I lock the
phone and put it in my pocket, sometimes I can hear my phone pocket
dialing. If I take it out of my pocket, I can see the emergency dialer
is open. Sometimes I can interact with the dialer and make it go away.
Other times, the phone is locked up and doesn't respond to touch events.
When it is unresponsive, if I long press the power button, I get the
dialog to restart or cancel but most of the time it doesn't respond to
events. When in this state, the only recourse is to reboot the phone.

I think a number of problem are here:
1. I know that before we could set a PIN, I would sometimes see touch events pass through the 'swipe to unlock' screen. This could be a contributing factor
2. swipe isn't taking into account pocket detection. The swipe happens too easily and then there is the pin/passphrase dialog with the 'Emergency Call' link to open the dialer available to be touched
3. at some point enough happens that the phone is no longer responsive to any input (other than the power button)

Within the course of one hour over the weekend, I had to restart my
phone 4 times. I am going to add the rtm14 tag and mark as Critical
because if this is not fixed, it will be a cause of returns. (FYI, f I
leave the phone outside of my pocket on the desk, I don't see lockups
very often).
