I am new to Android and I am hoping to find a comprehensive list of the icons popping up on the uppermost bar of the galaxy s4. I have found several short lists (those featured in the S4 user manual and on a various S4 sites including this one) but none that include the icons in question. One is on the left hand side and it features a lock icon with an exclamation point (in a triangle) in the lower right corner of the lock. Any clues?
Another is featured near the center. It is a standard cross with diagonal lines connecting each of the four points (think square standing on a corner with cross upright in center). This icon has three wifi bars projecting from the right hand side. Any clues?
Thank you in advance for the help.
