LG Optimus series

The LG Optimus series is a series of smartphones and tablet computers manufactured by LG Electronics. Optimus-branded devices have been produced running both the Android and Windows Phone 7 operating systems.

The LG G series is a line of high-end Android devices produced by LG Electronics. The "G" designation was first introduced in 2012 as a branch of the LG Optimus series for flagship devices, but LG announced in July 2013 that the "Optimus" name would be discontinued for future flagships in favor of maintaining "G" and "Vu" as distinct brands. The first purely G-branded phone, the LG G2, was unveiled in August 2013.
