Feature phone is more like Nokia 1100. No OS, may be Java. Cannot do much with it than making calls.

No it was not java its just simple OS or nokia generally used Symbian as their Main OS on their multimedia feature phones.

There is no more Nokia phones. They are all made by Microsoft and their feature phones use the Chinese MTK based closed system.

Nokia (not Microsoft) is going to release new phones with android soon. HMD Global bought 10 years license from Microsoft to make Nokia phones.
