So what's happening here is that you tell the sensors that the phone would be in landscape position (by shaking it), but you have an app focused which forces the shell to stick with portrait. Then, you start an app that supports landscape and unity will do what you asked it for, rotating to landscape.

I might be mistaken but this bug seems to be a new issue that arrived with the full shell rotation feature in wily. Using a phone while it's laying flat on the desk it sometimes rotates itself to landscape. Seems like we might have some over-sensitive accelerometer logic. $ system-image-cli -i current build number: 255 device name: mako channel: ubuntu-touch/devel-proposed/ubuntu last update: 2015-07-14 03:41:29 version version: 255 version ubuntu: 20150714 version device: 20150708 version custom: 20150714 To manage notifications about this bug go to: https://bugs.launchpad.net/qtubuntu-sensors/+bug/1474225/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
