I’m wondering why the kompakt constantly sends out cellular data signal while data is turned on but not if data is turned off? This phone has no side loaded apps. So for it to have no apps running that really need the internet, what is it doing and wasting data for? Here’s a video. You can see when I turn the data off it stops spiking the meter. https://youtu.be/7gZfaTZ4BkY?si=TzSyNM0VDbIKHCaR

Might the native “Weather” app be a source of that data traffic?

But it’s constant. I do not see a weather needing updated every few seconds

Have you tested for the same behavior on other cellphones?

Yes. Both my iPhone and android acts like that, but as you know they have the app stores and constantly update for notifications. That’s why I thought it was strange for this one since it has no App Store or apps to update constantly

This will be interesting. I would very much like to see the result as well.
Plus maybe try one measurement with the Offline+ activated.

What does the “updater” app do?

My understanding is that the native “Updater” app ‘phones home’ – through the data portion of one’s cellular plan – to Mudita to see whether any updates to MuditaOS K are available. I do not know whether the app ever does this on a schedule. I do believe that the app runs whenever you tap the gear > About > Software Update.

I found it. It was maps! I have never even used maps at all

Wasn’t Maps supposed to just receive GPS signal and not broadcast anything in return? I am getting confused…

Could be downloading some regional map in the background.
Anyone interested in the traffic could consider forcing the phone to use Wi-Fi and run Wireshark/tcpdump in your network to sniff the traffic (on a router gateway node or on a device in between on the path). Should shed some light on what, where and how much is being downloaded or transmitted.

It actually spikes rf on every mudita app. I installed foss equivalents from fdroid and disabled all the mudita apps and no more rf spiking!

Why in the world would the mudita apps do that? That is concerning. Do the Foss apps have less battery consumption too? How did you disable the stock apps?

Type these commands to disable them in adb.
adb shell pm disable-user --user 0 com.mudita.audio.player
adb shell pm disable-user --user 0 com.mudita.calc
adb shell pm disable-user --user 0 com.mudita.calendar
adb shell pm disable-user --user 0 com.mudita.meditation
adb shell pm disable-user --user 0 com.mudita.notes
adb shell pm disable-user --user 0 com.mudita.ereader

Thank you! I might do this. If the rf is high, the power consumption is also likely high. Considering the apps are as bare bones as it gets this is very strange.

This is a major bummer because I love my Kompakt so much, and I was so happy when it didn’t even ask to track me on setup. So I assumed it didn’t.
Scrolling through “App Manager” from F-Droid, it shows 2 trackers for Calculator for example (io.sentry.android.core.SentryPerformanceProvider and io.sentry.android.core.SentryInitProvider).
NetGuard confirms it connects to sentry.mce.one on launch. I did not yet bother to set up an AP and try to MITM it, so I can’t tell what’s in it.
I would assume that this is benign and truly anonymous telemetry that was just forgotten to be removed or to be made optional. A company advertising low RF and privacy would surely remove or make optional such tracking.

What’s the link to that app on fdroid? I’d like to check it out.
That’s interesting, I should find some time tomorrow to play around with packet capture.
