App Signature Verification on Android devices is an important aspect of mobile app security as it helps ensure the integrity and authenticity of any app before it is installed. The signature gets generated using a digital certificate, which will be issued by a trusted authority like Certificate Authority (CA). The verification process begins when the user attempts to install any app on their device.
Your mobile will check the signature of the app against the list of trusted certificates that are stored on the device. In case the signature isn’t found on the list, the app installation will be blocked and the user gets notified that the app isn’t trustworthy.
Users experiencing errors with App Signature Verification on Android devices
In most cases, the built-in Play Store may be sufficient enough for checking most of the prerequisites but in some instances, you may wish to make changes to the APK before installing it. For instance, if you wish to sideload an older version of any app, then doing so using the generic method could give you the INSTALL_FAILED_VERSION_DOWNGRADE error.
Meanwhile, if you are trying to install a modified APK file, then you’ll be greeted with the ignore invalid digest error. It’s possible that you won’t be able to allow overlay apps to be installed with inconsistent signatures. However, using a nifty workaround, you will be able to bypass these issues after you disable App Service Verification on Android devices.
