My LG G Stylo's GPS is not working properly since the 6.0 upgrade. I drive for a living. This is a nightmare. Tried Master Reset. No change. Took to Metro PCS and they said the phone was discontinued due to this issue (not sure if this is true). Called LG and they said I would have to send in my phone and they would "probably" be able to repair at "probably" no cost. But it would take 7 - 10 days and no loaner in the meantime. That isn't acceptable. What to do?
