Honestly i won't buy another wp phone for many reasons.
1. microsoft are doing bad and worse with the OS ,with windows 8 was great later windows 8,1 some functions like upload photos right to facebook and messenger chat built in has end and lost one of its charms as OS
2. Camera pro is great but is lacking more functions like light metering and others photo controls, i had a nokia 710 and in spite camera app was basic but it feels like more personalizable and i thought that with nokia camera it keeps but i was mistaken.if Microsoft has merged the functions of windows camera on wp 7,8 and the functions of nokia camera like shutter and more it would be wonderful.i am talking from pro point ( i'm professional photographer)
3. many apps are no so good made and many applications does no work anymore like instagram official app , also the lack of functions of some oficials app even the same functions like have instagram for ios or android that can upload videos or facebook for wp that almost never can upload a photo . is great 6tag but people wants official apps. official apps just a few does existl , even app like wordpress ,flickr , yahoo suite apps does no exist anymore on wp 8 and many official app that on IOS and Android are avaiable but on WP NOT.
4. the politics of expansion of MS on lumia no consider south america ,in fact i see more AD of iphone and galaxy and no one of lumia , even find a case here is almost impossible .had to buy on america a case for my lumia 830 .there is millions of accesories for iphone and android based phones availables on Chile but for a nokia lumia is like a challenge find it .
5.Cortana on spanish there will be also on chilean spanish ,we have no the same language structure as mexicans have also on voice commands is lacking many and is no equal on questions quantity as cortana on english, is stupid idea if i want use the question "what song is playing" must change the language of phone and location for use it .
6. i knew on a forum that panorama ,storyteller ,videoupload,refocus it will no be available on october , is a pity . i no get anything with a cellphone with a zeiss lens if i have no photo app for take advantage of the lens .
7.very bad policy that wm 10 won't be available on old lumias like 820 and others from x20 series (520,620,720,920,1020).
is very sad that a good idea Nadelya is killing step by step,like a sunset of a good idea and just focus on india and china being microsoft a global brand and like a global brand must do global products and the same care on america, india, chile ,etc no just focus on two markets and worldwide markets are no important.
