About this APK

Lie Detector Test Prank is an app by First Class Media B.V. in the Entertainment category, listed since at least March 2021. It includes native code only for ARM 32-bit, so it won't run on 64-bit-only phones such as recent Pixels.

Since version 1.4.8, the minimum Android version rose from 4.4 to 7.0. It asks for 24 permissions, 6 of them sensitive, including camera, record audio and approximate location. Compared with version 1.5.6, it adds 4 new permissions (“Camera”, “Read shared storage”, “Access adservices custom audience” and “Google Play license check”) and drops 1 (“Read media audio”). The app offers in-app purchases through Google Play and can read the advertising ID that ad and analytics services use.
