Now on my 5th unit in 14 months including 3 in the last month and a half. Verizon keeps sending me refurbished replacements, each with else something wrong. Have wound up wasting several hours every time setting it all up all over again. Worst battery life imaginable whether or not on 4G. Ever heard of a phone where you have to have 5 chargers and 3 batteries just to keep going? Locks up, shuts off, intermittent delays from a few seconds to SEVERAL MINUTES (no joke) when trying to make a call from the call log or going between screens. Half of my incoming calls wind up with a smashing static sound in my ear and/or just no voice at all. This model is an abortion and BOTH Samsung and Verizon should be ashamed to continue selling it.
