Here’s my ongoing little experience about this.
After some months with Blokada, and some advice from @harvey186, I recently moved to Tracker Control.
After some days with it, no issue, very smooth app, quite discrete about battery usage.
But when comparing to what blokada listed as blocked stuff … I found quite a difference.
And thinking it a bit, of course there is (I’m an idiot 
: Tracker Control blocks trackers by default, but not ads (see https://github.com/OxfordHCC/tracker-control-android/blob/master/ADBLOCKING.md) ; or at least not much, as the default hosts file shipped with Tracker Control is not aimed at that !
So I grabbed a good host file from Steven Black (https://github.com/StevenBlack/hosts) and imported it into Tracker Control (append mode, to keep original = default entries).
Let’s see how it goes :
- will some more blocked stuff appera in reports ?
- what about battery usage ?
Hoping this can help …
