Samsung Galaxy series of devices can almost be considered a pinnacle of smartphone engineering at this point. When you are talking about edge to edge displays or bezel-less displays, the one company that should be getting a lot of credit happens to be Samsung. The company released the first device with an Edge that was the Samsung Note Edge released alongside the Note 4, the device was not perfect by any means, but still showed an interesting concept with an edge on one side. However, that was just the start for what Samsung had planned.

Starting with the Galaxy S6, Samsung started releasing the "Edge" variants of their devices, alongside the flat-screen variants. As the name suggests, these displays were curved on both sides, basically eliminating the side bezels altogether. As time went on, Samsung only perfected their technology and nearly eliminated the top and bottom bezels as well by moving the front camera into a hole punch and a speaker grill in a very, very slim slit.
