The latest instance of this was my phone locked after too many unlock attempts while in my pocket making it quite inconvenient to take a picture. Contrary to my comment #6 I can trigger touch events through lightweight fabric like pocket lining. I disagree with point 1 in comment #9, If you can see the screen the proximity sensor will be disengaged. If you can't it should prevent the screen from coming on. That is: Event happens - proximity is true - screen off user takes phone from pocket - proximity now false - screen comes on unless timeout period has passed
I think all the issues with inadvertent touches are resolved by fixing this to keep the screen off until proximity is not detected. Also see bug #1426115 to shorten the time the screen is on when triggered by an event ** Changed in: canonical-devices-system-image Milestone: ww24-2015 => ww28-2015 ** Changed in: canonical-devices-system-image Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to telepathy-ofono in Ubuntu. https://bugs.launchpad.net/bugs/1291455 Title: [greeter] Screen and input should be disabled with proximity sensor when on greeter Status in the base for Ubuntu mobile products: Confirmed Status in Ubuntu UX bugs: Triaged Status in Unity System Compositor: New Status in powerd package in Ubuntu: Incomplete Status in telepathy-ofono package in Ubuntu: Invalid Status in unity8 package in Ubuntu: Incomplete Bug description: Steps to reproduce: * suspend your device * cover the proximity sensor (top left on mako) * call the phone Expecte result: * screen does not light up until you uncover the proximity sensor Current result: * screen lights up and you can answer the call This results in butt/pocket calls...
