It seems that you restored your device to factory settings. Your phone may have a Korean firmware as evidenced by the Korean characters on start up. (Samsung is a Korean company, by the way.) You can change that by tapping on the button below the Android icon when your device starts. If your phone boots up and still isn't using English as the default language, follow these steps:

I bought a new Samsung Galaxy S4. How do I enter my SIM card's pin code?

I do not know how to enter the pin code?

Take note: different SIM card providers have different default pin codes. Some use 1234, while others use 0000. The best way to determine which pin is used with your SIM is to look at the back of the card itself. It should show the default pin code for your phone. If the SIM card does not show it, try 1234 first and check if it is correct. Your phone will warn you about the remaining number of attempts before your phone locks itself for security reasons. If it is more than one, try the pin 0000. If neither pin works, call your cellular service provider to get the correct code.

My 2 week old phone is dark. It was working fine this afternoon.

The battery could have been low, but I have been recharging it. What should I do?

You should check your phone's brightness settings -- you may have changed them on accident. If your screen is just unusually darker but still working, it is most likely because of the brightness settings. However, if it's completely dark and not working at all, your screen or another component of your phone may be broken, in which case you'll need to get it repaired. Thankfully, since your phone is only two weeks old, you're still covered for free repairs under the manufacturer's warranty.

My phone has a prolonged Yellow SprintSpark screen when rebooting?

The phone has been showing the yellow SprintSpark screen since turning it back on for a long time. There is no Spark network in Milwaukee area yet. Is it just taking forever to reboot? It's been several minutes.

Was this helpful? Yes | No| I need help

If your phone hasn't booted up within a minute and a half of starting the boot up process, try taking the battery out and putting it back in. If it still doesn't boot within a minute and a half, take the phone into your local Sprint store to get it checked out for problems.

My phone reaches the Galaxy logo but doesn't get past it, and then it reboots.

My phone is trying to turn on, I see the Galaxy logo, but it shuts down again. We got a new battery, same problem. We tried a reboot, and pushed the volume up for second, but got the same problem.

Your phone is stuck in what's called a boot loop. This happens when the phone's firmware or operating system can't complete the boot process. The phone restarts itself to try again, but the problem persists. You will need to take your phone into your local carrier store or send it back to Samsung to get the problem remedied.

I downloaded and used the Button Savior (non-Root) App to restart my phone. It turned my phone off, but now it will not turn back on with the directions posted here, AND it will not charge when plugged into my laptop or wall charger! What happened? Does that App even work or did the software destroy my phone?!

Samsung Galaxy S4, power button stopped responding completely. I need to restart my phone every day to get service where I live. I downloaded Button Savior as you recommended, but when I selected "restart" on the App, it turned off my phone. Now my phone won't even charge (when plugged in to computer or wall, no battery icon appears). When I unplug and replace the battery, the phone vibrates once and the "Samsung Galaxy" in white flashed across the screen, but nothing else happens. I used the recommended "turning off" method, but the "turning on" method is not working for me, even if I am trying what the article says to do. I have tried: Literally exactly what the article told me to do. Like, exactly. I don't understand why this didn't work! I think it was caused by: Doing literally exactly what the article told me to do. Like, exactly. I don't understand why this didn't work!
