Microsoft promises its existing lumia phone uses they will all be upgraded to win 10 mobile & then trows most owners under the bus, saying that your phone is not good enough. Just as they did to win 7 phone owners, they are doing to win 8 phone owners.
I have a lumia 925, which meets the hardware requirements & runs the latest win10 insider build, really well, but now my phone has an unsupported OS, with no upgrade options.
who in there right will ever buy a phone with windows OS, if this is the way Microsoft will continue to treat its users.
Bottom line Microsoft should deliver what they promise.
Can you go back to Windows 8 or are you stuck on 10 insider now?
If you really bought the phone on the understanding it would get win 10 that might be a worthwhile CGA claim.
I'm thinking in your position I would be happy continuing with 8 as long as the security updates keep coming. That's the important part.
What windows 10 phone features could you actually need? ; )
