Currently have an LG G3 on verizon unlimited plan, which is still going great, but know it will probably die, looking for a verizon phone, did consider G5 (GPS problems), and V20 (signal problems) I need a phone that has 1) good signal retention in all areas as I travel in rural areas; 2) Good GPS is a must; 3) good speakerphone without feedback; 4) LTE/internet connection. Do not take pictures or listen to music so do not care now good/bad those features are. Also, would consider buying older phone from Amazon/ebay/etc that was an upgrade to G3 and meets my requirements? RECOMENDATIONS?????
