How Apps on Android Share Data with Facebook (2018)
The only way to crack down on this is to prevent apps sending any data at all and to minimise the use of proprietary software. As soon as your personal data leaves your phone and hits someone else's server they will sell it.Its a bit of a hard problem which we tried to solve using a permissions system but its a hassle because its hard to tell if a permission is being used legitimately and the average user just hits accept on anything because they don't know how to verify if something seems right.The GDPR was a step in the right direction where it allows you to say no to tracking and still use the service as normal.
