I'm of the opinion that pretty much every smartphone has become less reliable over time, with manufacturers focused more on being the latest and greatest instead of reliability. To that end, I've decided to start buying extended warranties. Verizon's is only a few bucks a month and covers the phone as long as I have it. There's no set amount of time, so I'll not have to worry about one of these issues popping up outside of warranty and leaving me hanging.
So having what amounts to a lifetime warranty, I'm not too concerned about LG's quality controls right now. Sure, I may have a slightly higher chance of a fault, but they are the only ones with the features I want the most. It's an inconvenience I'll risk for that trade-off, and I have backup phones if needed.
Keep in mind I'm not talking about full coverage insurance that includes loss or damage from mistreatment. That does cost a fair bit more and not what I'm buying.
