Samsung Gear 2 The most important part of the Gear 2 is its 1.63-inch Super AMOLED display that has got 320×320 pixel resolution. The bright screen adds a premium feel. The touch is responsive. The overall performance is good. I was able to answer calls while driving. The notifications for emails and messages appeared on the phone and I was even able to reach the content in the same. To save the battery, the display dimmed after a short period of inactivity. But with a flick of the wrist, it came back. The Gear 2 runs on Tizen, has got a dual core 1GHz processor. It has got a 2mp camera that snaps average images. This smart-watch takes a few hours for a full charge and continues to stay connected for close to three days.
