Can someone PLEASE tell me what to do?

You can try clearing the cache/data from the wifi app.And if that doesn't work.
Do a factory reset,Doing this fixes most issues like the one you have.

 

What Wi-Fi app??

And I don't see how doing a factory reset would make a difference since it's brand new and hasn't been altered.

 

Look in settings>>>apps>>>all>>>wifi.
In settings apps maybe app management.
Once you find the wifi app,Tap on it and clear cache and data.

 

There's no such thing on my phone. Wi-Fi is not listed in the apps.

 

There has to be,But go ahead and do a factory reset.That should fix it.
I need to know what device your on to tell you how to do it.
So,What devise you have?

 

I am not sure, like I said. Here is the link to the description of the one I have, but I don't know what it is. It's not too specific, really.

Mini S5 4.5 inch Android 4.4 Unlocked Phone SC8825 Dual Core 1.0GHz WVGA Screen WiFi Dual Cameras Bluetooth Function Supported (BLUE) | Everbuying.com

 

Try this method:

 

No, that isn't working. It doesn't matter what buttons I hold, it just eventually turns the phone back on.

 

Try holding the volume down and the power button at the same time.This should get you into recovery.

 

No. It doesn't do anything. The phone just comes on.

 

You have to hold them down until you see the 1st logo,Then you can release them.
If this doesn't work,The there is nothing more I can help with.

 

Then I guess you can't help because that isn't working. The most I've gotten it to do was go into Safe Mode.

 

Look in Setting for Backup and Reset.You can do a factory reset from there to.

 

Well, I found that and did it, but it still doesn't work. It's the same as before.
