Back in 2015, we saw introduction of devices like the One M9 and Galaxy S6, so you can expect more flagship announcements from the usual suspects -- including HTC, LG and, of course, Samsung, which is expected to reveal the GS7 and GS7 Edge .

While the show doesn't officially start until Monday, February 22nd , the action actually kicks off sooner than that, with many of the major companies holding their main press events tomorrow, February 21st. Stay tuned, as we'll be bringing you the latest news as it happens from Barcelona.
