I tested this bug on version RC-proposed revision 84 using a BQ device and when the proximity sensor is covered the screen will not turn on so there is no way to unlock your screen by mistake.
I have also checked iPhone 5 and the screen stays on when the proximity sensor is covered. Also you can slide anywhere on your screen to unlock your phone. ** Changed in: ubuntu-ux Status: Triaged => Fix Committed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1474363 Title: [greeter/unlock] "Unlocking swipe" is to easy to do on accident Status in Ubuntu UX: Fix Committed Status in unity8 package in Ubuntu: Incomplete Bug description: Use-Case: Your phone is in your pocket. You get a text message. You take your phone out of your pocket, and turn it in your hand so the front faces you. Expected behavior: The phone is still locked Behavior I get: 80% of the time, the phone is unlocked and I opened some app or menu I don't want. When you take your phone out of your pocket, the screen rubs against your leg and your fingers. This easily creates the sliding motion required to unlock the homescreen. Most android and ios phones use a small, 1cm thick slider to unlock the homescreen. This is a lot harder to do on accident.
