Apple’s Touch ID sensor has been the best and most reliable fingerprint scanner since it made its debut in the iPhone 5s, but competing products announced at Mobile World Congress this week could give the Cupertino company some concern.

Not only has Samsung made huge improvements to its own fingerprint sensor for the Galaxy S6 and S6 Edge, but Qualcomm has delivered an even more impressive alternative called Sense ID that works through aluminum, stainless steel, and more.

Samsung’s love affair with cheap, tacky plastic is on hold for its stunning new Galaxy S6 and S6 Edge.

Unveiled today at Mobile World Congress in Barcelona, the new handsets pull out all the stops in an effort to reverse Samsung’s declining smartphone sales and mount a new challenge against Apple’s most popular iPhones to date.

They sport all-new designs made out of premium materials, and vastly improved software that promises a better user experience. But they aren’t without their own compromises.
