    Windows Insider won’t work for me. It tells me there is a server error and that I should check my devices internet connection and its date/time settings. I use a Lumia 1320 and live in France.

    I know RAM might be the excuse used for not adding windows10 updates the early Lumia handsets like the 520 and so on.
    Third party apps often require an OS update, but if the company that makes the devices doesn’t make updates for their handsets. You might as well be saying “fuck you for buying our merchandise”.
