Best school is oldschool; at least that is what Motorola seems to suggest. According to The Wall Street Journal, Motorola plans to release a new Razr smartphone during the upcoming MWC event. Younger ones from you may not remember it, but Razr was a series of flip phones very popular around years 2004-2007. We do not know if the new smartphone will be a flip phone or a more modern foldable device, but it is more likely to be the latter - flip phone would most probably not cost 1500 dollars, which is supposed to be new Razr's cost.
WMC 2019 will take place in 25th - 28th February.
