I'm trying to get general device information (e.g. Name, Brand etc..) on Firefox OS but i'm struggling with the "Settings API"https://developer.mozilla.org/en-US/Firefox_OS/Platform/Settings_list and this set of API is available only for certified apps.
Is this the only way? How can I access to Device Name?
You can use navigator.userAgent [1] to see name and brand of some devices without any permission.
For Alcatel One Touch Fire, for example, you will get: Mozilla/5.0 (Mobile; ALCATEL ONE TOUCH 4012A; rv:18.1) Gecko/18.1 Firefox/18.1
Keon and Peak, unfortunately, will only return a generic UA. You can see more UA strings at [2].
