Firefox OS/Metrics

This is a placeholder page for design / discussion around Metrics in FxOS

Phase 1

Requirements

For User Benefit, knowing the following information will security updates and app functionality

1. Build IDs, Country, Operator, OEM, Version of HW: These are needed for Device Updates and Security patches: When a bug is found, or a security risk is detected, they need to be sent as an update to the particular OEM, Operator.
2. Screen Height, Width, Pixel density: This is needed for CoreApps development (Gallery, Camera, Dialer, Browser) and 3rd party apps. These apps need to know the screen sizes, resolutions that they would need to support.

Design of Ping

Delta to what exists today

1. Is triggered through the first-time use experience / activation. Will automatically retry until it is successful (on a 1 hour interval)
2. Never pings again once it is successful (unless the phone's "userdata" partition is formatted through the recovery partition, but this is not a case we support generally, it means wiping all of the user's data)
3. Can also be disabled, but requires extra work on top of disabling app updates or removing the Firefox marketplace app
