++ the future of Microsoft Lumia mobile phones ++

Don’t know if this will help, but

If you have a WIN10 laptop or desktop, you can run a USB cable that’s standard on one end to the PC and the micro USB end in the other. The phone will slave power from the PC port, but nothing else.

The Windows File Explorer should either see the phone as an attached USB device or try to install a driver so that it can do so. Once you have a link allowing you to see the files on the phone through the file explorer on the PC, you can transfer files or delete the ones you don’t want. On my old Lumia, these were typically pictures or audio files.

Hopefully, this will free up enough space for you to start working again.

++ if the memory fails, then probably you will need to change the hardware (new hardware is only available for the rival platforms), but at least your account & app library lives on & Windows 10 mobile will be there in 2020 ++ I think Microsoft should have aimed for the potential 40-50 million Windows 10 mobile fleet or install base (as the industry says it) ++ a distinctive OS almost has guaranteed a loyal follower base (it is important to be #1 to these 40-50 million customers & if they bring the customer to the center of their strategy then they will have a future & a growing install base) // ++ recently I have studied the drama of the Star Wars franchise & may the force be with Windows 10 mobile //

PS : from personal experience I can say that these memory problems can occur after approximately 5 years of usage //

"Windows 10 Mobile, version 1709 will reach end of service on January 14, 2020. Devices running Windows 10 Mobile and Windows 10 Mobile Enterprise will no longer receive monthly security and quality updates that contain protection from the latest security threats. "

Windows 10 Mobile is getting one more update. Hackers will not target Windows Phones, way to much security and too little market share, even if there's no further security updates. Microsoft has had over 2 years of bug fixing, stability improvements, and security updates. Lumia's running 1709 are basically a fortress of security, this has ruined battery life though, especially when using Edge. Aside from that, incompatibility with other devices make W10 Mobile harder to breach, this wasn't intended as it makes Lumia less useful.

I'm not saying they can't, but what are the chances of you encountering someone trying to hack a Lumia? Because I haven't seen another person with a Lumia this entire year.

I hear you, Szilard, but it’s all water over the dam now. They simply abandoned the project and wrote it off on taxes. €5.4 billion for the Nokia purchase plus whatever else they invested. In 2015, Microsoft took a $7.8 billion write-down on the Nokia purchase. All chump change to them. In 2017 Belfiore revealed that Microsoft had ceased the development of new Windows phones and new features for Windows 10 Mobile, citing the losses in market share and lack of app development. Belfiore is another one that just didn’t get it.

I edited my earlier post to reflect what I was attempting to get at concerning Store apps. I was speaking of commercial customer apps such as for banks, investment firms, retail stores, fast food chains, utilities, government agencies, train & bus lines, gas stations, and so on. Yes, plenty of game and productivity apps, but the other apps are what’s important to users as well.

Along the way I would email companies as to why they didn’t offer the Windows version of their app. A standard reply was on the order of “We don’t feel the need to invest in that right now” or “We have no future plans for that”. That’s why I stated they should have created a commercial Store app department, even if they gave the apps away and lost money. So they write off a billion or so. So what? They would’ve been billions ahead in due time. Other solutions as well such as a folding phone so to use as a pad. Or a pad that makes calls. How about a Surface mobile? Easily performed with or without wired or Bluetooth ear buds. But no! Let’s just abandon the whole project altogether. Let’s just sell Nokia to an Android OS loving company. What a crock!

So now I have an OS-unsupported $500 boat anchor. A hacker’s dream come true. No thanks. I’ll move on the best I can. I’ll simply abandon my Lumia and root my new phone. Now that I’m retired, I have time to fiddle with this stuff.

Cheers

+my opinion is that Mr. Gates is not addressing very well his "biggest" business mistake : first of all the company leaders have abandoned the Lumia ship in 2016, when the situation was not so bad 2% - 3% market share vs. around 20% for Samsung or Apple (all this with minimal marketing & distribution strategy efforts; the company has spent more for the acquisition of GitHub than for the Lumia division); secondly if you make some mistakes you try to correct them & not abandon all the project & the idea of Windows on a phone (live tiles, which btw could be even better with fluent design elements built into them) ++ the app problem is easy to solve : who needs & who can handle millions of apps (most of the users need a couple hundred or even just tens of apps & the company's mission would have been to study what apps are actually really needed)

++ so the company's support for Windows10 mobile is on life support (some Microsoft apps will be still supported in 2020 as well) & there are still enthusiastic developers who lend a helping hand to the platform : Gameloft updates many of its games & likewise Extreme Developers (e.g. they have a brand new game available on mobile for those who like history & the era of battleships ++ USS Monterey for example) //
