If you’re an Android user experiencing unexpected ads after phone calls, it’s important to recognize that this is not a new feature to adapt to, but rather a form of ad fraud. Researchers have uncovered a network of applications on the Google Play Store that employ a tactic known as AfterCall, allowing them to display intrusive advertisements over the Android interface.
How ads are taking over Android calls
This deceptive practice often starts with seemingly benign utility applications, such as calendars, alarm clocks, and notepads. Upon installation, these apps request overlay permissions, which enable them to appear on top of other applications and subsequently display ads during phone calls. By detecting the end of a call, these applications can launch full-screen advertisements disguised as call information screens. This clever ruse makes it less likely for users to suspect any malicious intent, as the ads appear to be part of the standard call interface.
It’s crucial to understand that overlay permissions cannot be granted through a typical pop-up during the installation process. Instead, they fall under a category of “special permissions” that require users to navigate into their system settings to enable. While Android apps are expected to request these permissions transparently and provide a valid rationale, AfterCall scammers often cite reasons such as alarms needing overlay permissions to function correctly. In some instances, users may find that the apps crash if they decline these permissions.
How to remove AfterCall ads
The challenge in addressing these ads lies in their unexpected appearance—surfacing after a phone call and featuring content unrelated to the utility app in question. Since these utility applications do not overtly appear malicious and often do not show up on recent app lists when the ads are displayed, pinpointing the source of the problem can be quite difficult.
For those encountering ads post-call on their Android devices, a thorough check for apps with overlay permissions is advisable. Users should navigate to Settings > Apps > Special app access (which may be found behind a three-dot menu) and select the relevant permission type. Here, they can identify unfamiliar applications or those that should not possess “display on top” permissions and proceed to uninstall them. Regular audits of these permissions are recommended, disabling any that are not essential.
While these applications may primarily serve as an annoyance rather than outright malicious threats that compromise sensitive data, the risks associated with installing programs that request unnecessary permissions cannot be overlooked. Ultimately, these apps not only waste advertising dollars for brands but also risk tarnishing their reputation among users. However, for many, the primary concern remains finding a solution to eliminate these disruptive ads following phone calls.
