Hi @iamnarendrasingh and happy new year to you too.
Wow, that is a big problem indeed. What Android version did you see this problem on?
Clients send a user agent string with every HTTP request. It will contain a string that includes device information that looks something like Dalvik/2.1.0 (Linux; U; Android 8.1.0; Android SDK built for x86 Build/OSM1.180201.007) which could be logged. How and when you do it will depend a lot on your backend and user setup but perhaps that gives you enough to start working with.
I think that providing a metadata option to get that user agent string in a form submission is also a very good idea.
