Oh god, next year, if anything have changed, I'll move to nexus... I tried to support Wp 8.1 for a long time, but its very, very disappointing... I have been optimist for 2 years, its time to say the truth guys, we all know that windows phone will fail... WP 8.1 is there last chance.
Oh how wrong you are, you have no idea. Recent numbers shows the WP8.x OS is gaining more and more attraction world wide, and his "progress line" is upward, not downward. Go ahead, use Google to google it.
It's not the MS or OEM's to blame here, it's the carriers who needs to be blame for taking too long time to approve the updates and roll them out. Samsung stated that all his WP8 phones will be supported with the new firmware who is already in final stage. Phones mainly included here are ATIV S and ATIV S Neo and ATIV SE.
And i am little bit confused with some of your statements in your post. I don't know, maybe it's a simple typo error, for example"
"I tried to support WP8.1 for a long time..." - First of all WP8.1 is out for 3 months already and it's not official its Developer Preview, so basically means it's BETA or GENERIC if you prefer more. Ofcorse it will have bugs. But if you meant WP8, then thats another story, which brings other confusion... Why did you bought the WP8 device in a first place? I assume that you got sick of Android and wanted to try something new so you give it a try to WP8. Does your WP8 device suit you good so far? Did it provided the necessary things you do on your smartphone in a daily basics? If Yes, then what else do you need from your WP8 Device? Just don't tell me "The Apps" cuz that answer is long gone now since the WP Store grew a lot. More and more official apps are getting in the store every day. We got so many good 3rd party apps that provide even better user experience than the official one. So, "The Lack of Apps" is not the answer you need now.
