March 1 will be a very important day for Samsung and HTC, as both have scheduled MWC 2015 press events for that day. The two companies have made it pretty clear that they're going to announce their next-generation flagship smartphones on March 1: the Galaxy S6, and the One M9, respectively.

While the handsets that precede the S6 and the M9 - Galaxy S5 and One (M8) - are very different devices when compared to each other, the new models are expected to have quite a few things in common (besides Android Lollipop). Note that we're talking about the regular Galaxy S6 and One M9 here, not about the S6 Edge and M9 Plus.

There are (at least) 5 features that both the Galaxy S6 and One M9 will most likely offer - although, of course, we'll be able to confirm them only after Samsung and HTC announce the two smartphones.
