Just when you though OEMs were already settled in their own, single-letter kingdoms, they kick up the dust once again. Sony drops the Z for the X and Lenovo/Motorola drops the X for the Z. While LG has more or less been happy with its G, it has also recently put out an X screen and an X cam. Now it seems it like the Korean OEM is preparing to have another X join its army. A trademark filed in Korea reveals LG trying to reserve the rights to an "X5", hinting at what might be a cheaper version of the LG G5.
