Hello to all of you.
Many thanks for your replies and advice.
I have installed Exodus and I only found one app with 1 tracker, which is from Google… Whatsapp. The tracker is Google analytics.
I know there are many alternatives to Whatsapp (Telegram, Signal…) but I work for an association that still uses this app. So I guess I have no choice for this one until the people I work with are convinced that we all should forget this app…
I also installed Netguard but I am not sure about which app I should chose to allow/block.
How do you know if the app is a “fishy” one or not ?
For the moment, I denied wif-fi and mobile for all apps except those that should communicate with some external device to work (for instance: web browser, messaging app, podcast, radio, F-Droid,…)
In fact, I guess my device is now as “clean” as possible, given that I cannot root it (and still use the original OS) and that I decided to install WhatsApp…
Where do you find package names ?
I am aware of what you say in your last sentence but as I am a complete newbie, I don’t know how to distinguish between “good apps” and “bad apps”…
Since I couldn’t “root” my device (didn’t find any compatible FOSS OS and/or don’t have sufficient technical skills and knowledge nor days to work on this), I have to deal with vendor apps which I cannot uninstall.
I apologize for any misuse of the english terms below. My device is configured in my native language and I don’t know the translation in english.
For some apps, I am able to “de-activate”. For others, I have only one option visible: “force shutdown”.
For instance, when I go to “parameters”->“apps”, I see many applications that I didn’t install myself, like “camera”, “SIM toolbox”, “Documents”, “E-Mail”, “Clock”, “Launcher3”, “Music”, “Downloads”, “Phone” and even “Parameters”…
Of course, I have already “de-activated” all apps with the world “Google” inside…
What should I do with these apps ? I guess most of them are harmless but I want to understand this complex world of Android that is new to me.
