A trademark application was filed with the USPTO (United States Patent and Trademark Office) this month, clearly relating the G3 name to “mobile phones.” Usually, trademark applications are reviewed by the USPTO “approximately 3 months after the filing date”, so we assume that LG will have full rights over the G3 name starting May.
Coming as the successor to the well-received LG G2, the G3 might become LG’s first smartphone to use a Quad HD (1440 x 2560 pixels) display. The screen could measure 5.5 inches, this giving it an incredible 534 ppi density. The new smartphone may also feature an LG-made octa-core 64-bit processor, and 3GB of RAM.
Later this month, LG should officially announce a G2 mini and a new G Pro 2. The latter will have a rear camera with enhanced OIS+ technology, and we're expecting this to be among the features of the G3 as well.
