Hi, i miss icons showing network activity in the top (arrow up and down)
I found on f-droid a app call Throughput that suppose to insert those icons close to connection icon but I deed see is five years old
I wandering if can be installed on GOS pixel 6

Following the subject! My wish is the same...

The OS doesn't support it and as you say targetSDK for apps is particularly important for device security.

You can however use an app like Shortcutter:

This will add the relative info to a QS tile.
The feature is premium and requires Play Services and an account to purchase right now however LeeDroid the dev is working on the next release:

And I have requested a non Play dependent method for it:

I am not affiliated and there are probably other methods ie widets and apps that provide it.
