Remove google-dependencies

As Android / LineageOS is a google software, there are some sentinels deeply baked in the system. Here we will remove them.

1. DNS

Not every server name should be resolved by google:

Navigate to Settings - Network and Internet - Advanced - Private DNS
Enter new DNS: dns3.digitalcourage.de

2. google captive Portal

The question whether you are connected to the internet should not be googles decision:

Replace google captive portal check with Kuketz. Therefore, connect your Fairphone to your computer and execute following adb commands:

adb shell 'settings put global captive_portal_http_url "http://captiveportal.kuketz.de"'
adb shell 'settings put global captive_portal_https_url "https://captiveportal.kuketz.de"'
adb shell 'settings put global captive_portal_fallback_url "http://captiveportal.kuketz.de"'
adb shell 'settings put global captive_portal_other_fallback_urls "http://captiveportal.kuketz.de"'

In order to test if the settings were correctly adopted, type in your terminal: adb shell 'settings get global captive_portal_https_url'

3. google print service

Did you ever use the google print-service? If not, let's switch it off:

Switch off Print Service (Settings - Connected devices - Connection preferences - Printing).

4. Phone number lookup

LineageOS uses an online look up for the entered number, but that is not their business.

Switch of the forward lookup, the people lookup and the reverse lookup (Telephone-App - three points in the search field - Settings - phone number lookup).

5. Alternative Browser

Do not trust googles Browser

Open Fdroid to install a Browser. We use Fennec.
Open Fennec and install "privacy badger" & mBlockOrigin as add-on.
Drag your Fennec-App-Symbol to the browser location (at the bottom of your screen) & remove chromium
Set Fennec as you standard browser.

6. Location Tracking

Nobody should track your location:

Check Privacy Settings and GPS (especially browser-settings for Fennec).

7. Browser search suggestions

Not every stroke on your keyboard has to be sent to the search engine, especially not to google.

Choose another search engine e.g. startpage or duckduckgo (Browser - Settings - Search)
Switch off the search suggestions (Browser - Settings - Search - Show search suggestions)

8. Deny net access for untrusted apps

If you have to use less trustworthy apps, a firewall is very usefull. We use NetGuard.

FDroid -> search for NetGuard -> install.
