Cyngn has struck a deal with TrueCaller to integrate it with the default dialer app on Cyanogen OS 12.1. For a privacy-conscious person like me, it was totally unacceptable given the notorious reputation of TrueCaller. Read this post on XDA-Developers for more details.

Here is how I got rid of TrueCaller. Before installing the OTA on my OnePlus One, I turned off mobile data and Wi-Fi so that I could prevent any internet access till I removed TrueCaller. The phone rebooted after installing the Cyanogen OS 12.1 OTA update (which has been pulled due to some issues at the time of writing this). Immediately after that, I opened the dialer and was prompted to enable TrueCaller. I refused it by selecting Not Now.

I also went into the settings menu of the dialer app to make sure there was nothing related to TrueCaller enabled by default. All this just disables TrueCaller but does not remove it entirely. Read on if you want to completely remove it.

Since the TrueCaller app does not show up in the App Drawer, go to Settings ? Apps ? All and scroll down to the TrueCaller Service app. Tap on it and uninstall it from the App Info page that shows up.

Uninstall TrueCaller App

Now your phone should be free of TrueCaller and its privacy issues. If you go to the settings menu of the dialer app, you can verify that there are no settings related to TrueCaller.

This should work for any device for which Cyanogen OS 12.1 is released.

In case you have a change of mind after doing this and want to reinstall TrueCaller, you can do that by navigating to /system/vendor/bundled-app/TrueCaller folder using the File Explorer app and installing the APK that is there. The /system/vendor/bundled-app/ folder contains the APK files for all the other pre-loaded (but removable) apps like Boxer, Browser as well.

Hope this helps 🙂

GNOME 3.14 supports captive portal handling but it is not enabled by default in Debian Jessie probably due to the privacy concerns. To enable it, create a file /etc/NetworkManager/conf.d/20-connectivity-debian.conf with the following content:

[connectivity]
uri=http://network-test.debian.org/nm
response=NetworkManager is online
interval=300

Then restart NetworkManager using the command service network-manager restart as root user (or use sudo if your non-root user has sudo privileges). Once this is done, whenever you connect to a network with a captive portal, GNOME will automatically open the captive portal login page where you can login to get access to the internet. Please note that the requests to the connectivity test URL could be logged and be aware of its privacy implications though no personally identifiable information is sent.

This is very helpful for me since my ISP ACT Fibernet requires its users to login to its captive portal before allowing internet access. Hope this is helpful for others. The configuration given above tries to reach the specified URL once every 300 seconds and tries to open the captive portal login page if it is not reachable. This could cause the NetworkManager applet to try opening the login page if there are any issues with the internet connectivity. So feel free to tweak the interval according to your needs.

GNOME Software application automatically downloads the packages to be updated and presents a notification in the notification area. It might be a good idea to disable it avoid excessive data usage on metered internet connections.

To do it from the command-line

$ gsettings set org.gnome.software download-updates false

Or open dconf-editor and navigate to

org -> gnome -> software

and unselect this key

download-updates
