You can find the list of compatible Android and iOS smartphones on the faq
I was not talking about smartphone models, but about actual version of Android operating system supported 
Latest version of Android is 13, but is cryptoplatz supported for older Android OS 4 or 5?
Reason I ask this is because I have some ancient Android smartphone I could use for this purpose.
Sorry, CryptoPlatz App is compatible with Android 4.1 and above
