Buttons didn't work referring to the navigation UI buttons. It took good couple weeks for it to arrive. I was looking forward to it. Expecting the Evo4g 3D like I had back when it came out around 12yrs ago & I really loved it. This very little & cheaply refurbished version is disappointing. Worst of all I contacted the vendor about it and sent video proof they requested . Still haven't heard back from them 🙅
