>How does one find out if an app is stealing data on your android phone maliciously? I.e. data, texts, photos, videos etc.

Use something like Wireshark or another package sniffing tool.

Why are you putting information that you want to keep secure, on a fucking cellphone? Are you an idiot or something?

The confidentiality problem of android apps is a popular CS research subject since 2011, you can search google scholar with keywords like "android privacy leaks" and it will yield a lot of results.

There are some related open-source projects about program analysis that I know of:

Also there exist some noob friendly products on market, but most are expensive and enterprise targeted.

I personally use replicant now and it's really nice to see that there is no play store installing itself some new update without asking you.

Only replicant can say that they have almost solved the problem (waiting for a phone with libre hardware).

But wile we have to use satellites with non libre hardware and software controled by govs no phone will be secure

>In March 2014, Replicant developers found and closed a backdoor present in a wide range of Samsung Galaxy products that allows the baseband processor to read and write the device's storage, sometimes with normal user privileges and sometimes as the root user depending on device model. It is unknown whether Samsung's proprietary firmware for the radio chip can be remotely instructed to use these access features and whether the vulnerability was introduced with legitimate uses in mind.

>have no google products

>install xprivacy and set all apps to request usage of all permissions

I've caught 2 apps that were only using internet to send analytic data or advertising data.

The best solution, though, is to use open source software.

Root your shitbrick and uninstall all the google apps. Now throw it out your window and go pick up an old nokia or something.

Thank you for not using the revelant sticky.

What were you thinking?

use XPrivacy, AFWall, Bootmanager.

Only install applications from F-droid.

After that, if you want to be super autistic, use Tasker to auto-set Airplane mode when launching a proprietary application.
