Tired of seeing Samsung and HTC hog the limelight for Android handsets this spring, LG is planning to launch a new smartphone of its own on May 30th. Per Techradar, LG has sent out press invitations for a May 30th event in Macau for the unveiling of an unnamed smartphone that in all likelihood will be the sequel to the Optimus G. The tagline on the invitation is “ImaGination Begins,” with an emphasis on the “G,” so it’s almost a sure thing that the device will be some new variation of its Optimus G series that includes both the original Optimus G and the new Optimus G Pro. We got our first glimpse of what could be the Optimus G2 in leaked pictures last week, although we still have no idea what kinds of specifications the phone will have.
