The market of featurephones and apps on them is way bigger than smartphone market what everyone in tech world is talking about. It is way undervalued. But there are some issues: a) no proper infrastructure/ecosystem so far. Elements like this in-app purchasing help a lot here. Ovi Store in phones is terrible compared to AppStore counterparts, for both developers and endusers etc. Very limited monetization options etc. b) low-end smartphones are coming to this market, Huawey provides almost as cheap Androids as Nokia nowadays in Africa. c) fragmentation for developers. Why can't Nokia do one really good cheap phone which fits 90% users. Always they announce 4 marginally different ones, just so different to make developers mad and stick to Android/iOs.
