Notification symbol that looks like a lightning with a small download symbol n

[Android Central Question]

The symbol is not lite up but is in my notification bar. A lightning with a download symbol ( arrow pointing down a bar). It to the left of my WiFi and to the right of my alarm notifications.

Welcome to the forums. Do you have a Samsung device? It sounds like Download Booster is enabled. Usually you can enable/disable this feature in the quick settings panel.

Having similar issue and download boost isn't on am wondering if it's some means of spying as have seen the word and others flash very briefly when a sceen change takes place
Sounds weird i know
