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.
