Samsung galaxy s4 call log arrows
My aunt and uncle got me the Samsung Galaxy s4, but I've never had a cell phone before (usually whoever I'm with has a cell I can use if needed), and I'm not 100% sure what the colored arrows next to each number in the call log mean?
The green arrow means incoming call (someone called me)
The orange arrow means outgoing call (i called them)
but I'm not sure what the red "broken" arrow means (it looks like the arrow was headed towards a floor, hit the floor and started to bounce off the floor back upwards)
does anyone know what the red "broken" arrow symbol means next to a number in my call log?
(i thought maybe it meant I missed that call but I know there was 2 other calls before that number that i missed and their arrows where green, but this number has the red broken arrow)
