I partially agree. The FM radio on my LG G4 works fine, until it gets stuck and requires a reboot. The NFC radio has never worked. And after 1 year my LG G4 developed the infamous "reboot loop" issue. It just randomly restarted one day, got halfway through the restart, and restarted again. And again. But customer service was fine for me. I was able to ship it to them, get it fixed under warranty, and have it returned within two weeks.
Unfortunately LG insisted on using FedEx, and marked it "signature required", and "do not allow holding for pickup." There was literally no way I could get the damn phone back without working from home for a day and _hoping_ (since FedEx can't guarantee) that they would retry the delivery on that day. WTF would you disallow holding for pickup at a nearby store??? Why would FedEx even provide that option?
