At $679.92, the Samsung Galaxy S6 from T-Mobile isn’t for everyone. With the speediest processor available on an Android and its streamlined, jet-set looks, it is one flashy phone to pull out of your pocket. A slim 2.78 inches, the device is easily navigated with only one hand, unlike the company’s Note 4. Its richly-colored display offers superb resolution, easily seen even in bright sunlight. The only drawback, however, is that it does not offer buyers the opportunity to expand the device’s memory.
