I just got my first smart phone yesterday, and I'm feeling pretty stupid. I can't even get the phone to stay on. It's fully charged. I press the power button, the home screen comes on for 2 seconds, then the screen goes black. It will power back on if I press the button again, but the same thing happens every time. LG support has frustrated me further by not listening.. they keep telling me to go into settings. I keep telling them the screen doesn't stay on long enough to do that. Can anyone please help?
