WM10 is DEAD IN THE WATER - a sunk ship that the sharks above (Android and Apple) don't even care about as a threat to their market share and profits.
eg. I was using the Lumia 640 for a year to beta test it. Hardware had so much potential for the price point.
But, update after update, even simple things like the camera went from great quality and speed to so-so and sometimes crashed (huh? Just how much re-coding is going on behind the scenes of a simple camera app to make it crash??) Edge couldn't handle some sites correctly, like Wikipedia, when the fonts were set to 125%+ under accessibility, even after months and months of waiting after reporting the issue. Groove couldn't come up with a Folders view despite asking time and time again.
All Microsoft seemed to do was to either put in more useless features - like epub reading mode in Edge when epub apps were already in the store - change icons in the settings just to change and add icons - and ignore really simple things.
Like if I only have internet on my phone, and try to setup my phone with my microsoft account, it now wants to send a two-factor to my microsoft email. BUT, I can't access Edge to get online to check and verify, because it won't let me pass, so I'm now stuck. If I don't do this, there's no way to RESTORE my saved account settings and such back to the phone after I skip the initial login verfication - ie. Microsoft is SO dumb, you can't add an account after the initial setup to restore a phone using just the phone?!? So now, I'm forced to find a computer to log in to my Microsoft email simply to setup my phone after a reset/etc. where I want to restore my phone info from backup.
And in the end, promises that are so easy, like Android apps on WP ala Blackberry, were not kept. Heck, you know when XDA folks are installing Android OS onto WPhones that it can be done even at the OS, rather than app level, so what's keeping one of the biggest IT companies in the world with supposidly brilliant programmers away from expanding their market share instantly to all interested users in the world? The dumb CEO in charge...
Finally, the thing that killed it for me was the lack of apps and apps being pulled from the market.
Whether it's something as simple as Flickr, Pinterest, Chase, etc, or more complex, it's sad that WP didn't even bother to emulate Android compatiblity ala Blackberry. It would have been so simple, but the dumb Microsoft CEO refused, and that was the end of that.
$40 Lumia 640 got kicked out, a $80 LG G2 brought in. And startling?
1. Same size, but G2 has a bigger 5.2" screen in the same body vs 5"
2. 13MP camera vs 8MP.
3. Faster 800 processor vs 401.
4. 4x the memory.
5. Everything Android runs on the LG G2 whereas few apps run on the 640.
Basically, same price range, but far, far better, more useful, feature-packed, etc.
And more useful! MICROSOFT must be the DUMBEST ===PHONE===maker on the planet if it can't put a dialpad button on the home screen like every other phone on the planet. WP is the only stupid OS where I must press several icons/choices to get to the dialpad. Somehow, the lame programmers at Microsoft thinks every contact is already in my contacts list, or I want to add every business/unknown/infrequently used contact to my contacts, and thinks that is good enough to have as an icon from my home page. INSTEAD OF A SIMPLE DIALPAD ICON!?!??!?!??!?!
WP died for me because every time I dug into this app, that feature, this setting, it was a Wth!?!? moment. Things that have been in other phone OSs for decade+ were missing in WP.
The latest WP update has done nothing to correct the many problems I've noted, so it's definitely end of the road for WP period, IMO.
