++ the future of Microsoft Lumia mobile phones ++

I think the mistakes MS have made in Mobile (and in other consumer hardware they have attempted) are deep routed in the consumer psyche at this point and will not be turned around with product improvements or 'new' versions.  

++ I have still in mind the real danger posed by some flagship devices of the competition some years ago (overheating beyond limits) & now they have made their way to the company store // so problems can be solved, if there is the required will // the stock market is in a bull stage, the cloud based services also having their boom, but market trends probably will change in the future & if the company wants to compete with its rivals to be & remain a 1 trillion company, then it will need Windows Mobile as a service // the fundamental problem is that the mobile platform is not a priority (although the company has the synergy with UWP & in a decade there will be a 4 billion + smartphone market ) //

I have been a loyal MS Mobile for years starting with Mobile 6.x on a Motorola Q9c and currently Mobile 10 on a Lumia 735. I would love to see the Lumia line move forward, but neither MS nor the app development community seems willing to put skin in the game and here, in the USA, I don't find carriers interested in phones with the OS.

I have recently been seeking support for email issues that have appeared out of the blue and have found the very same problem among other Lumia owners with different models. The pattern indicates a systemic problem within the OS, but MS has essentially turned a blind eye to support questions of many sorts from what I can see which is somewhat understandable given their recent end-of-support announcements for the mobile OS.

Support for a Lumia future is inseparable from support for the OS. If we have the latter, we won't have the former.

I agree with what your saying but once again, you are ignoring the main point. at this point customers will not buy microsoft mobile because they don't  trust the brand, this excludes people like us who are perhaps more technically aware or less willing to accept the walled gardens and intrusive social media aspects of other brands but we are by no means a platform for a global mobile business.

Agreed the only way we can move forward is to help ourselves. If it all possible. When i switched phones and hit email problems a complete reload of the o's fixed it using the insider preview

Sadly, even MS people don't trust the brand.

I have a client that is a long time MS partner who, like I, was waiting for Windows phone to move forward. The killer for him was attending an MS conference about a year ago where he watched MS reps using iOS and Androids and none with a Windows phone. Within a short time, he'd moved to iOS especially as part of the conference was demonstrations of interacting with MS cloud applications on these other phones without having a corresponding app for Windows Mobile.
