we offer fast, accurate and
up-to-date device detection
solutions for creating great mobile web user experiences. To do this we maintain a database of 80,000,000+ headers to make sure we keep our 99.9% detection accuracy. This means any new device that is released on the market must then be entered into our database. It is important to us that our users know where we source our information from so that they can remain comfortable, knowing that our information is accurate.
The properties for each Hardware
Device profile are manually populated by our professional
team using multiple official and unofficial sources. As these properties are
essential to optimising the mobiles performance with the web we do our best to
get it right. We also try to develop strong relationships with manufacturers
enabling us to create a database that is both accurate and up to date.

unofficial sources had occurred and it became apparent that the majority of these

the manufacturers get official information wrong occasionally.
At 51Degrees.mobi we aim to retrieve accurate
information about every device that we use in our database. Our professional team use a combination of
sources including: Official websites and technical documents, unofficial mobile
news websites and physical devices to create the most comprehensive list of
device properties available.
