Android Apps Share Location Data With Advertisers by Default

A recent investigation by the Electronic Frontier Foundation (EFF) revealed that many Android applications contain third-party code that automatically transmits users' precise location data to external companies, including advertisers and data brokers, once location permission is granted. There are no specific location permissions for Software Development Kits (SDKs) on Android, meaning that granting one app access allows all bundled components to access the same data. Developers may be unaware that their apps are configured to share location histories with external firms, as advertising SDKs often prioritize data collection for revenue generation. The EFF calls for advertising SDKs to stop making personal data sharing the default setting and urges developers to disable unnecessary data collection. Location data can reach data brokers, which may experience breaches, compromising user privacy and security. This situation poses hidden risks for investors in the mobile advertising sector, as legal challenges and reputational damage may arise from regulatory scrutiny of location data practices. The EFF emphasizes that app-level permissions do not provide meaningful consent for third-party data sharing, highlighting the value and risks associated with location data.

DoubleVerify finds dozens of Android apps a month showing ads after calls

A recent analysis by DoubleVerify engineers has identified a trend in mobile advertising known as AfterCall ads, where applications display advertisements immediately after a phone call ends. This practice generates hundreds of millions of impressions monthly and raises concerns about user experience and brand integrity. AfterCall applications operate using three components: a misleading permission, a Broadcast Receiver to capture end-of-call events, and an Activity to display ads. The SYSTEMALERTWINDOW permission allows these apps to show content over others, often granted under false pretenses. They utilize Android's telephony system to trigger ads post-call and employ tactics to obscure their presence, such as removing themselves from the recent apps list and using innocuous icons. Detection is challenging due to the lack of shared codebases and the obfuscation techniques used. The scale of the issue is significant, with numerous AfterCall applications identified monthly, negatively impacting user experience and raising concerns for advertisers.

My parents’ Android phones were ruined by invasive ads. Here’s how I fixed them for good

Mobile advertising on Android devices has seen a rise in deceptive pop-ups that mimic legitimate notifications or system updates, leaving many users, particularly less tech-savvy individuals, vulnerable. A personal experience highlighted this issue when a family member fell for a misleading PDF ad, leading to the installation of multiple fraudulent applications. Recently, similar deceptive ads were encountered on YouTube, raising concerns about the safety of family members who rely on their devices for important tasks. Discussions on platforms like Reddit have pointed out the prevalence of misleading ads on family-friendly platforms. The author expressed a desire to block all ads if companies cannot ensure their safety. To address the issue, the author sought an ad-blocking solution that allows for remote management and network-wide filtering, ultimately choosing NextDNS. This content filtering solution offers a free account with sufficient monthly DNS queries and supports individual profiles for tailored settings. The setup process for NextDNS involves creating profiles for each family member, allowing for distinct settings and blocklists, and configuring devices with the provided DNS-over-TLS endpoint details. While NextDNS is effective, it does not eliminate all ads, particularly those from platforms like YouTube, indicating that additional measures may be necessary for comprehensive security. Regularly reviewing app permissions and uninstalling unnecessary applications are also recommended for enhancing security.

As Google sits back and watches, terrible ads are ruining Android’s free app ecosystem

The mobile advertising landscape has shifted from simple banner ads to aggressive monetization tactics that often manipulate users. Common intrusive ad experiences include unclosable interstitial ads, interactive playable ads that mislead users, and unsolicited notifications promoting unrelated games. This shift has negatively impacted independent developers, who struggle to compete against large ad networks and feel pressured to adopt disruptive ad practices. Google, which controls the Play Store and ad services, benefits financially from these intrusive ads but has not effectively addressed the issue, allowing low-quality ads to proliferate. The current state of advertising is eroding user trust in free applications, threatening the integrity of the Android ecosystem.
