LG sought to reinvent itself this year and got the ball rolling on two things. It created new product lines, Universal and Explorer, for "normal" and experimental phones, respectively. It also adopted a new naming scheme that moved away from single letters and numbers to make its phones more memorable. After the LG Velvet and the LG Wing, the company's next unconventional phone might be the LG Rollable. That is at least based on a trademark filing in Europe and it leaves little to the imagination what it could be.
