1. If you love or like this platform stop complaining and use the platform as is.
But what about when they remove the features that made me like WP in the first place?
2. Use official apps over third party apps more frequent.
Why, if official apps are crap/non-existent?
3. Don't be cheap support your favorite apps and games developers no matter what the cost.
I gladly but an app or a game, even more so if I know that an indie developer is behind it. However, when I send an email asking the developer about a feature that is not available in the demo, and costs 2? extra (plus additional 2 to remove adds), and I get no reply, why would I waste money on something that may not work as I want it to? 'It's only 4?', yes, it's not a lot, but there are developers who respond in an hour, and I'll rather buy their apps. Unfortunately, I don't make a million a month, so I can't just go buying all the apps there are.
4, Support your favorite OEM:s.
I don't understand this, I already have a Nokia phone, am I supposed to buy every new phone they release and wear their T-shirts? When they offer an amazing phone with no compromises, I'll support them again (glance, no yellow tint in camera, no overheating, etc.)
In the second quarter, Microsoft's smartphone shipments dropped to 7.4 million units from 8.2 million in the same period of 2013. At the same time, the Windows Phone global market share fell from 3.4% to to 2.5%.
No wonder, there has been so little new phones available. 930 is unappealing to me as an upgrade from 925, because it doesn't have glance and there's no sd card slot. If they released a radically different (better) phone, I'm sure it would succeed. For example, built in 64GB basic, and 50? extra for 128GB built-in storage. Stores sell 64GB flash drives for 20?, isn't it about time we drop the 16/32GB phones and advance? Also if they offered something extra to WP users, it would be nice, like a BETTER skype experience than on other platforms, MORE onedrive storage (you don't get '15GB with windows phone', you get 15GB when you create a M$ account, it makes no difference if you even have a smartphone. If they offered 50GB to all WP users, or even 1 year of office 365, they would boost the sales a lot. Free maps are a good step in this direction though.
Yes, HTC One M8 is now also on WP, but it's aging hardware already, and except for software, it offers no extra advantages over it's android brother. Toss in a free bluetooth headset or something, and not just for US.
Is MSFT is to blame for this decrease or would you blame the Windows Phone community?
Read above. Also coming from little country in the middle of Europe, I never get any special treatment from any OEM, while there are constant rewards, free services, freebies with purchase etc. going on in US and maybe UK. When they realize they can do something extra for other countries as well (after all, WP is more popular in Asia and Europe than US) maybe they would gain more users.
Windows Phone community is great though, but it's not like a few enthusiasts can save a platform.
