I actually don't have a smartphone right now, but the last one I had was an LG Spectrum.
I detested it. The main issue I had with it was that the battery came broken on it, a common issue apparently from Googling the problem. Having a smartphone die after an hour or two of light usage isn't fun, especially considering it performed rather badly with freezing up so you're spending precious battery life trying to shut down and start it up again, etc. Quite annoying.
It wasn't all bad with it, though. It had a nice sized screen and everything looked pretty good on it.
Overall, definitely wouldn't recommend it to anyone.
