Aftercall adware hides in Android tools, shows post call ads

The article discusses a new wave of deceptive Android apps known as "Aftercall" ads, which generate ads after users finish phone calls. These apps disguise themselves as common tools (like alarm clocks or calendars) and request overlay permissions to show ads in a full-screen format. They make it difficult for users to uninstall them by hiding from the recent apps list and presenting ads as part of legitimate call functions. The article advises users to check apps with overlay permissions and use anti-malware tools to detect and remove these fraudulent apps.
