I'm running Oreo 8.1.0 on a Xiaomi A1. In the status bar I see the following three similar icons, never more than one of them at a time; for none of them can I find info by searching online, nor at https://material.io/tools/icons/?style=baseline . What do they mean, please?

  • One of them is a solid equilateral triangle, with a vertex at the top, occupying the top half of the status bar.
  • One is a solid equilateral triangle, with a vertex at the bottom, occupying the bottom half of the status bar.
  • And the third is the combination of the other two.

I guess you think on up/down arrows next to WiFi signal indicator. They are called network activity arrows/indicators. Those arrows are showing when there is network activity. Arrow pointing up means you are uploading data (doesn't necessarily mean that you are uploading a file but rather that there is network activity, when you search something on Google you need to send data first - request to be able to receive) and arrow pointing down means that phone is receiving data via internet. They can appear separately or both at same time. They also appear next to cellular signal strength if cellular data is active. Sometimes arrows are inside of WiFi/cellular icon it really depends on device manufacturer.
