Phone won't turn on at all
My phone froze on the "Samsung logo" start-up screen and did not want to shut off with just the power button. I held the power, home, and volume buttons to boot into Recovery Mode and it did. I chose to boot it up normally but then it froze on the Recovery Mode screen. I held the power button down to shut it off then it didn't want to turn back on so I plugged it in. When I did, a green screen was displayed with some OS options, so I chose to start it up with the existing OS. Now it doesn't want to turn on at all and doesn't show the battery screen when charging. Please help. Thank you.
