Nokia Lumia models:

Lumia 1520, Lumia 636, Lumia 638, Lumia 720, Lumia 730, Lumia 730 Dual SIM, Lumia 735,  Lumia 830, Lumia 920, Lumia 925, Lumia 928

  • Fixed an issue where the phone’s display wouldn’t turn off in close proximity to your face when in a call and using Continuum.
  • Stylized buttons in notifications are now aligned to the right – consistent with other system buttons in dialogs.

  • Has this information been confirmed for the Lumia 920? Is it really possible to upgrade to the latest Fast Ring build? Thanks.

  • “phone is up to date” nokia lumia 920, windows insider app running on fast ring, please help :(

  • Kapil Arya

    ^^ Re-sync your Microsoft account. If issue persists, wait for another build release and then see if you can get that build.

  • My L920 has been stuck at build 10586 – encouraged by this site, I tried to reset my phone to defaults, reinstall Windows Insider Fast Ring, but still no updates. Maybe I’ll have to wait for another build but it’s getting quite old and I fear being left behind. For the record, I still prefer Win8.1 on my HTC 8X but losing out on some apps :(

  • Kapil Arya

    ^^ You won’t be left behind, as if you download next latest build available 😊

  • Lumia 650 not getting build 15007.
