Smartphones are the same PCs in a small body. This means that they have their own OS. Each OS has some version and build number. Each new version vendors provide some new functions, patches, API changes and so on. Therefore, we can get different errors on different OS versions.

iPhones: Settings/General/About/Version

Androids: Settings/About Device/Android version. Also, Model number is very useful.
