Unknown system app FP4 Android

Hi, does anyone know what the App “Radikal” does?

It shows if you navigate to all apps and Display system apps.

Couldn’t find anything online about it but it only shows under System apps.

Running Android 15 the very latest update (works well btw :blush:).

Thanks.

Your screen(shot) is missing the package name which indicates its some kind of font the name is com.android.theme.font.radikalsource

As Radikal is German maybe its coming from an App

ChatGPT says

Using ADB you can check with

adb shell dumpsys package com.android.theme.font.radikalsource

or

adb shell pm path com.android.theme.font.radikalsource

Where its located, if its /system, /system_ext, /product oder /apex, it would be part of the System.

Does anyone not located in Germany have it?

Given the package name it sounds as if it was the package for the front called “Radikal”, see Radikal Font Family - Befonts

I’m not near a PC right now, might try later to pull the package from my FP4 and see what it contains.

$ adb shell pm path com.android.theme.font.radikalsource`
package:/product/overlay/FontRadikalSource/FontRadikalSourceOverlay.apk
$ adb pull /product/overlay/FontRadikalSource/FontRadikalSourceOverlay.apk
/product/overlay/FontRadikalSource/FontRadikalSourceOverla... 1 file pulled, 0 skipped. 1.6 MB/s (8542 bytes in 0.005s)
$ file FontRadikalSourceOverlay.apk
FontRadikalSourceOverlay.apk: Java archive data (JAR)

JARs are just ZIPs with a defined file/folder structure. It mainly contains a file called resources.arsc and the extension hints at “Android Resource Storage Container”.
I don’t have Android Studio on the current PC so the analysis stops here, but so far it looks consistent with the assumption that it adds the font named “Radikal” to the Android system.

I have that too on my FP4, but at the bottom, where on the screenshot above we only see “version 1.0”, for me it states:

version 1.0

com.android.theme.font.radikalsource

So it definitely seems to be a font.
