Symbols that appear on Samsung cellphones include a small radar, which means that Wi-Fi is switched on, and a signal strength icon, which indicates the strength of the network signal at a location. The flight-mode symbol, indicated by a small plane, shows that flight mode is activated.
These symbols appear at the top of the screen. The symbol of a battery shows how much power is remaining, usually with the aid of a color. The battery also indicates when the phone is charging.
Symbols such as G, E, H and H+ show the kind of network that is in the surrounding area. G stands for GPRS, E stands for EDGE, H stands for HSDPA, and H+ stands for HSDPA+. There is also the 3G symbol, which indicates that there is a UTMS network, and 4G, which indicates that there is an LTE network. The two arrows that appear under these symbols indicate whether the Internet connection is working properly. Whenever the symbol R appears next to the signal bars, it means that the phone is roaming.
The symbol of a closed envelope shows that there is a new message. An upside-down teardrop symbol indicates that the phone's GPS service is on. An exclamation mark that is inside a triangular shape shows that there is an error.
