My phone had been doing this for a month now. Every time I leave my house or job my phone don't work. Samsung was supposed to give an update to fix this issue. They did, Now it works here and there. It will work for 5 minutes then cut off. I need my phone not just at home. I can't Google maps to get somewhere that I don't know. I can't research something, make a call, send a text. Nothing that you need you data for. This is crazy Samsung please I'm begging you to fix this issue. For everyone
