This means text and images pop when displayed on a black background, as most of the Fitbit OS is. The biggest complaint I had with the first Versa was that its display was LCD, and Fitbit has now upgraded to an OLED with the Versa 2. The most significant improvement on the hardware side of things is the addition of a new OLED display. The device now has one button instead of three, which I'm okay with as it makes the external design look much cleaner, and Fitbit has removed its logo from the very front of the device to give it a cleaner look too. To start, the device is a tiny bit thicker, but this is unnoticeable when on you're wrist. Coming from a Versa 1, the Versa 2 is an all-round pretty subtle upgrade over the first generation, but there are upgrades worthy of note here.
