Sharing of location data by mobile OS is almost impossible to turn off
Consumer organisations from Czech Republic, Greece, Norway, Poland, Slovenia Sweden and the Netherlands have filed a GDPR complaint against Google over tracking in Android. According to the complaint the mobile operating system uses a variety to techniques to make it near impossible to turn off location tracking. The existing controls are deemed deceptive and ineffective.
"There is no real option to turn off Location History once it has been enabled; users can only pause it after the Google account has been created. Users who attempt to 'pause' location history receive vague warnings that this will limit some functionalities." – Forbrukerrådet
