I just started with the development of a watchface for Tizen/Samsung watches (native application). Should I select the latest Wearable version 5.5 in Tizen Studio expecting that it is backwards compatible with older devices? Or should I select an older version like 3.0 so that the watchface runs reliably on older devices?
The way to go in Android is to always choose the latest SDK version and when there is a function, that is not supported on older versions, to make a case distinction and implement the code for those older versions.
Thanks for any help
You can start development using Tizen 4.0 as it is stable now. Tizen 5.5 will be released soon but some of current devices may not get Tizen 5.5 updates (Gear S3, Gear Sport etc). So, to cover the most devices you should pick Tizen 4.0.
