I dont understand the frenetic attention to an announcement to an in line upgrade to an existing line of phones. In the S7/Edge case, the leaking rumours are more numerous than the icebergs in the ice field that sunk the Titantic. Good grief. Chill, people. The MWC web site --
https://www.mobileworldcongress.com/ -- has various resourses, brochures and an app that tells all on its home page. Instead of watching the shilling from various outlets on the 'net, I opt to watch the BBC 'Click' show --
BBC World News - Click -- available on most cable TV systems. Spencer Kelly and his minions do a decent job getting the story and filtering out the noise. Alternately, in past years manufacturers and Verizon phone carrier web sites had new pages posted virtually simultaneously with the new product announcement. The Twitterverse will be ripping: search on such tags as #MWC, #Barcelona, combinations thereof and brand names and models. But remember, it is just a phone with incremental features over a decent -- note I didn't say great -- S6. And remember to breath.
