Recently, my Samsung GN3 has begun losing 4G LTE more and more regularly. This morning it dropped to 3G and never came back. I have spent most of the day researching online and I have not been able to find a solution. I have tried many of the tricks and settings I've seen on similar posts. I have pulled the battery & card; I have checked the network type and I've even tried Safe mode. I just tried to call support but they are now closed. I am in an area where I have always had 4G (Indiana) and now the phone hasn't said 4G at the top all day. Even the 3G is going in and out and occasionally it shows 1X or even no service. It is a SM-N900V. Software was updated 3 months ago to Android 5.0 (lollipop). Love the phone. Not sure if the issue is with the GN3 itself, 3rd party software, my account settings or something stupid I am overlooking. Any help is appreciated - love the phone. Thanks, Scheu
