Microsoft executive Gabriel Aul suggests that those who already have updated the Lumia 550 to preview Build 14267 and are experiencing these issues, to roll back to Build 10586. To do that, sync the phone to your PC by using the USB port. Open the Windows Device Recovery Tool, and choose "My device was not detected." Once that is done, tap on Lumia and reboot your handset. The Windows Device Recovery tool will detect your phone and re-install Build 10586.
As we said, Build 14267 has a bug that needs to be exterminated before you can install it on the Lumia 550; once it is cleared to be installed, the update will add a music search icon on the upper right of the Cortana screen. If you want to know the name of a song that is playing, open Cortana and tap the icon. The virtual voice activated personal assistant will reveal the name of the song and the artist.
With Build 14267, Microsoft has enabled Word Flow for the address bar on the Microsoft Edge browser. In addition, the update makes it easier to open InPrivate tabs on Microsoft Edge. Right next to the new tabs icon, you will find the button to press when you want to open a private browsing session. And a prompt in Edge will let you know when a download is starting, allowing you to cancel one that has started by accident. Photos can be added to Skype messages by tapping on the paperclip icon on the lower left of the screen, while composing a message to a contact. Or, the camera app can snap a photo that will attach to your Skype message.
Unfortunately, all of these changes are going to have to wait if you're rocking the Lumia 550. If you haven't yet installed Build 14267 on that model, wait for the all-clear sign from Microsoft. If you already installed the update, use Aul's workaround to get back to Build 10586. Time heals all wounds, and eventually Build 14267 will be cleared for takeoff.
