The Samsung Galaxy Tab 4 NOOK’s Status Bar

By Corey Sandler

As if owning a Samsung Galaxy Tab 4 NOOK weren’t status enough, in the status bar you can see how well connected your tablet is, how full of energy it is, check its watch, and more.

The time of day

At the right corner of the status bar is the current time. You can customize that, too: Adjust the date and time, select a different time zone, use the 24-hour or military clock format, or change the date format.

  1. Swipe down from the top of the screen to show the notification panel.

  2. Tap the Settings (gear) icon.

  3. If it isn’t already selected, tap the General tab at the top.

  4. On the left panel, locate the Device Manager section and then tap Date and Time.

  5. Change the settings on the right side of the screen.

The life of a battery

You can see how much power remains in the internal battery by looking at the can-shaped icon next to the time. If it’s full, your tablet is full of power. If it’s almost empty and looking a little red, recharge it. (If you’re using the tablet while it’s plugged into its recharger, you’ll see a black lightning bolt within the battery icon, telling you that the juice is flowing in.)

Don’t let the battery die back to nothingness. That can damage the battery. Also, don’t try to replace the internal battery. It should last a few years. Contact Barnes & Noble or Samsung directly if the tablet needs a battery transplant.

Wi-Fi connection

Although you’ll use the reading and other apps without an Internet connection, most of the time you’ll want to be in communication by Wi-Fi. The icon’s presence (a pie wedge with curved plates) means the Wi-Fi system is active and connected.


If you see arrows moving up or down from the icon, that means information is exchanged with the Internet, including email services.

Depending on your settings, you may also see four other communication icons:

  • Wi-Fi Direct. Similar to the standard Wi-Fi icon, this icon’s arrows go left and right instead of up and down. This icon appears if you’re using your tablet in local communication with another device that can exchange data without going on the Internet.

  • Bluetooth. A stylized angular B tells you that the tablet’s Bluetooth radio is active; you need to pair your tablet with another device and exchange security codes.

  • Connected to Computer. A pitchfork-like symbol indicates that your Tab 4 NOOK is connected to a desktop or laptop computer. Confusingly, this icon can appear either in the notification panel (on the left) or the status bar (on the right), depending on the devices you’re using.

  • Nearby Device. If you’ve allowed nearby devices to come within the cone of connectivity of your Tab 4 NOOK via Wi-Fi, Wi-Fi Direct, or a mobile hotspot, you’ll know it when you see this icon, a little tablet that seems to be doing the twist.

Other status or notification icons

Here are a few more you may see from time to time:

  • Mute Enabled. A little speaker with a slash through its cone tells you audio has been silenced. (Wouldn’t it be nice if you could aim that at the kids who want to loudly chat all through a red-eye flight to Istanbul?) You can mute your tablet by merely pressing and holding the – side of the Volume button until it is all the way off.

  • Alarm Activated. Not a burglar alarm — a wake-up alarm. You can set an alarm, with a musical salute, from the Alarm Clock app. When it’s on, a reminder appears on the notification panel.

  • Airplane Mode Activated. If you turn on Airplane Mode (the quickest way is a two-finger pull from the top of the screen and then touching the icon) the tablet turns off Wi-Fi and Bluetooth radios but otherwise works. This way you can read books and use certain other apps, but block communication.

    A little jet airplane appears in the status bar to remind you that the radios are off. Retrace your finger-steps and turn off Airplane Mode to turn radios back on.

  • Blocking Mode. Turn on this feature to block notifications, alarms, or both. Tap the Settings (gear) icon, choose the Device tab, and then tap Blocking Mode. Do this if you’re in a place where noises are inappropriate, or if your tablet is on public display and you don’t want other people to see your alarms or notifications. This icon, a slashed circle somewhat like a “Do not enter” sign, appears in the notification panel.

  • Error. Houston, we have a problem. If you see a triangle with an exclamation point in it, do not panic. Yet. Shut off the tablet, go for a brief walk around the office, and then turn it back on. Shutting off the device might clear memory of corrupted data. When all else fails, call Barnes & Noble or Samsung.
