I show you how to get into developer options mode within your Samsung Galaxy S4.
-Go to Settings
-Build Number - tap 7 times until is says you are now a developer.
-Tap on back button and you should see "developer options" icon next to "about device" icon.
"Read about each of the settings within the developer options here: http://www.androidcentral.com/all-about-your-phones-developer-options"
"Take bug report: Tapping this option grabs the current log files on your device, packages them up and prepares them for sending to, well, whomever you want to have it. It takes a minute or two after you tap it, and you'll see a notification once it's ready. Tap that notification to send it on it's way. Swipe it away to cancel.
Desktop backup password: You can use ADB to backup and restore things like apps and their associated data to and from your computer. This option forces a password on those backups, and they can't be restored without that password.
Stay awake: Checking this box will force the screen on your phone to stay on anytime and every time it is plugged in. This works with a wall charger or your computer's USB port, and is a great way to make sure you burn images into your screen. Don't use this one unless you need to!
Select runtime: Here is where (for now)you choose to use Dalvik or ART. ART is still experimental and what we have now isn't what will eventually be released in Android L. Some phones really don't like the current ART runtime preview, so refer to the forum for your particular device before going there.
Enable Bluetooth HCI snoop log: Sometimes, a developer (or security specialist) will need to capture and analyze Bluetooth HCI (Host Controller Interface) packets. Enabling this will place them in a file on the device storage (/sdcard/btsnoop_hci.log) for retrieval. You can then analyze them with a program like Wireshark.
Process stats: Everything you ever needed to know about the running processes on your phone. Go ahead and tap it, then tap one of the entries. For the layman, it's just a lot of numbers, but for a developer debugging his or her app, this information might save the day.
USB debugging: This is what allows your phone to communicate over the USB port on your computer via the Android Debug Bridge (ADB). You need to enable this to use things like DDMS, or to use ADB commands."
