"Njanga speakers have remained relatively isolated from the direct influence of the Fulbe. Their village is comparatively underdeveloped and less modernized. Indirectly, however, population movements stimulated by the Fulbe arrival in the region brought Njanga speakers into closer contact with speakers of the neighboring dialect Sundani, which has now fully replaced the Njanga... There are now only four remaining speakers of Njanga plus six rememberers, and it has no function, everyday or ceremonial, that is not met by the replacement language. For this reason, Njanga is moribund. Unlike Wawa, the threat to Njanga is not Fulfulde– although almost all people of Mbondjanga speak Fulfulde–but Sundani, a sister dialect and the replacement language."

The language is "no longer spoken at the village level, but essentially used only in the home, or perhaps among friends."

"It is spoken only by the chief of Mbondjanga and his notable, or dignitary, on a more or less daily basis ("i.e. at some time during the day"); it is not known to what extent it may be understood by older people in the village."

"[Njanga] is considered to be a dialect of Kwanja... The Njanga have increasingly intermarried with the Sundani, another Kwanja group, and their dialect of Kwanja is the one now used almost exclusively in the village. A small and decreasing population, together with (or resulting in) the increasing intermarriage with Sundani has apparently been the primary factor in the decline of this language."
