For both Android and IOS Validic’s Mobile SDK currently supports the current OS and 3 previous OS. This is a rather generous level of support considering most organizations support current OS and -1. The adoption of the new OS for IOS users is rather quick, and though in Android there can be lag, the majority of the market share is in the current OS and -3. This website gives a nice visual of the Android OS market share.
What if a Validic end-user has an older OS that isn’t supported?
They can try to use our mobile SDK with their older OS. It may work. It may not. We won’t be able to offer support for older OS and would suggest that the end-user upgrade the OS on their phone to continue using our product.
