I think it is TTY,its for deaf people,you can turn that option off
The TTY option is turned on. you can turn it off in the setting>phone>TTY
You can turn off lamps from the iPhone 5S by swiping up from the bottom so as to access the Control Center and then tap on the Flashlight icon.
The symbol you are most likely talking about is the TTY symbol, which would appear in the menubar of your phone. It indicates that TTY is enabled for iPhone users who are normally deaf or hard-of-hearing. If you do not want this feature to be enabled, simply go to your Settings app and tap on Phone, and then tap on the TTY slider to "Off."
If you are using iOS 7/8 then you go to the bottom of the screen and slide up. This should pull up icons. You need to select the flashlight icon to turn it on or off.
The App Store should already come with your iDevice. If it doesn't contact Apple Support or go back to the place you purchased and inquire the features of your iPhone. If the icon is not there maybe there is an Restriction on your iPhone. To turn it off just go to Settings > General > Restrictions >Turn off. And the App Store should appear on your home screen.
