The down arrow indicates that the device is receiving data from the network, pointing downhill traffic. These little arrows are useful to know if the device is actively using the Wi-Fi connection and to Identify potential connectivity or speed issues.

In addition to helping diagnose possible connectivity problems, the information it provides is used to evaluate the quality of mobile network coverage offered by the operator.
The arrows that appear next to the connection icon Bluetooth They also indicate data transfer activity, but in a connection context between devices. That is, the arrows They appear when the mobile is connected to another device and their absence indicates that there is no connection. To reflect the data transfer between the two, the arrows light up or appear off, but are always visible while the mobile is paired with another device.
