LG has not yet unveiled the G3 yet but that has not stopped the specs of the mini version of its upcoming flagship from leaking on the Internet. According to the documents that the folks over at MyLGPhones have stumbled upon, the LG G3 mini will be codenamed B2 mini (G3 is codenamed B2) and will sport a 720p resolution display of unknown dimensions. 

Other interesting details revealed by the document include the device running Android 4.4 KitKat with a new version of Optimus UI on top of it. The rear camera has also been confirmed to sport a resolution of 8MP, though it is not yet confirmed whether it will feature OIS or not.

Sadly, other specs of the handset are not yet known. Lastly, the leak also suggests that the handset will be making its way to all the four major carriers in the United States: AT&T, Verizon, Sprint and T-Mobile.

While the images of the handset have not yet leaked, expect to sport the same design as the G3 and will be sporting rear-mounted buttons as well. LG is expected to announce the G3 within a couple of months from now so expect the G3 mini to break cover only after its big brother is launched.
