Signature verification failed Android update zip

One may wonder what is Android Signature Verification and why it is needed while updating. So let’s begin with some theory behind it.

Android Signature Verification

In every Android device, by default Android Operating System requires all the signed orders to install it. To check the legitimacy of the application and identify the author of the application which is needed to build the trust based relationship between the apps. When we install some applications a valid signature is sent from the developers of the application, which may or may not need some private data to process the same. This signature helps to check

  1. APK was not tampered by anyone from the time it is being signed.
  2. Installed version by matching apps certificate.

This is actual work that runs behind the screen when we install something on our phone. It is a kind of security check to whether the currently downloaded application is legal or not. If the certificate matches then installation will be continued and also it retains the data. If the signature is invalid i.e. doesn’t match APK’s contents or the certificate is not matching the original application, then there is no further continuation of the installation process.

Benefits of Android Signature Verification

1. Security

It provides a security feature to your device that protects your data from the apps we install without knowing their legality. Only checking the signature, allows the installation to be complete. To a certain level, it provides basic protection to the device without any cost. As it is pre-build in the device, we don’t need to do any work for this.

2. Communication between the system and application

When we want to install some app on our device we are not going to check who is the developer, who is the distributor, or its legitimacy. But this Android Signature Verification checks it by communicating with the app by checking its signature and certificate. If it meets all the checks then it will be installed.

3. Driving license of apps

It is like the driving license of the apps. If the app or that APK has a signature or certificate then it is permitted to be installed and worked on the device. If suppose it is not matching the certificate or the signature is not valid then it will be not privileged to work with the system.
