NEW YORK (AP) — Samsung unveiled new smartphones with largely unchanged designs and incremental improvements such as a better camera — accompanied by a second annual price increase for many customers. The static design of the new Galaxy S9 underscores both the slowing pace of smartphone innovation and the extent to which other manufacturers, particularly Apple, have caught up with Samsung features that once stood out. That includes everything from edge-to-edge screens to facial recognition to a water-resistant body.
