Samsung Electronics Co. showed off virtual reality hardware alongside its latest Galaxy S7 smartphones, in its latest attempt to breathe life into its premium line and wrest ascendancy back from Apple Inc.

The new phones go on sale on March 11 sporting a 5.1-inch screen using its own Exynos or Qualcomm Inc. processors, with a larger 5.5-inch Edge model equipped with the same kind of wraparound display the company debuted last year.

While they look almost identical to the S6 line, Samsung is bringing back a memory card slot and adding a longer-life battery after the absence of a removable power unit alienated fans last year.
