Over the last few years Samsung has tended to keep things quiet at MWC, preferring to hold a separate Unpacked event a few weeks later. This year the Unpacked event will be held at MWC on Sunday March 1st according to the invite sent out.
The invite confirms the event will be in Barcelona at MWC and teases a curved edge design similar to the side of the Note Edge. This could mean the S6 will have a curved screen or that there will be two versions, similar to the Note 4 and Note Edge which were announced together. We will have to wait until next month to find out. Thankfully February is a short month so it’ll fly by.
