Nokia will do well on Android (or as well as anyone that isn't Samsung can do these days). There's already a high demand for these phones especially in India etc where Nokia is still a very strong brand. I'll definitely be buying whatever the top flagship model may be (P8/P9?). The rumoured specs look awesome and the build quality so far with the low to midrange models have been top notch. It'll also be running close to pure Android so that's gonna be popular with many Android fans and will mean fast and early updates on the software front.
I can't see them ever doing a Windows version at least not any time soon. They've built strong ties to Google now and will want to prove themselves to them
India's definitely a wildcard as a so called "emerging" market. Still, in budget they'll have to take on xiaomi, Lenovo etc, and in premium they have to take on Samsung and apple. Premium brands still have growth in india, so brand power like say, apple is apparently very strong.
Everyone's fighting for india in a way. Apple and Samsung just poured a mountain of cash into advertising in places like india, and xiaomi has been quietly working on expansion into the budget market in india for at least a year already.
Perhaps as you say, the brand name nokia still has value enough to compete with the likes of apple and Samsung, or the budget models can compete on price with Chinese companies....but even hearing what you say I am still sceptical.
Companies like HTC have really struggled to break through (and only did recently in the US). Outside the big two, its mostly budget budget budget, and that fish pond is loaded with hungry competitors....(xiaomi, Lenovo, oppo, Huawei, alcatel and more, all with some serious distribution networks already set up - and for phones distribution is major)
I guess we'll see!
Actually counter to the original posters question - if nokia as android flops, and windows phone gets a boost from the various new hardware and software intiatives (windows s, windows on arm, Andromeda, whatever is happening to win10m after the FCU)....will nokia come crawling back to windows phone?
I'm definitely a outside the box thinker, feel free to call be a dreamer, but I don't consider either of those impossible or even unlikely. Together maybe slightly unlikely. But not impossible.
There is a reason why players like TCL and HP, coship and whartonbrooks have flirted with win10m. Because that android market is a nightmare to find a place in. Easier to make a big piece of a small pie, no one is fighting for, than get a crumb from a large pie there is an all out war over.
