Meta was found to be tracking Android users' online behavior, even in incognito mode or when using a VPN, raising concerns about user privacy.
The tracking method involved collecting private browsing data through the Meta Pixel script, bypassing incognito mode, VPNs, and Android's app sandboxing.
This data collection aimed to improve personalized advertising on Facebook and Instagram, but was done without user consent, drawing criticism.
Google and Mozilla are working on patches to prevent similar tracking in the future, while the incident has raised questions about iPhone security compared to Android.
