My phone would quit working no calls out no calls in no text not even emergency calls I would have to power it down and start it back up to get it to work maybe sometimes I had to do that two to three times before I would start working went to spectrum where I got the phone and had my service after about 3 to 6 months of playing with them they told me to call Samsung because they wouldn't replace my phone still under warranty called Samsung they told me I would have to drive to West bend which is approximately 40 miles from my house leave my phone there go home and go back and get it when it was repaired if they could repair it if not Samsung would replace it that's over 120 miles plus wear and tear on my vehicle my time all for a phone that was under warranty and should have just been replaced if you don't have somebody local to fix it the place I bought it from should give me a new one worst service ever will never ever buy another Samsung product I now own Motorola and went to US Cellular where there is never a line of people waiting for help
