      1.) Downloaded upgrade advisor 2.) Checked Enable windows upgrade 3.) started downloading update in phone setting now, here is the issue as i started downloading it worked perfect unless and until it reached 8% .... after reaching that it displays error message ( error 801882d1 ) i have performed hardreset as well as soft reset which later results of no good. i have tried updating 4 times with no luck.. Anyone have anymore suggestions ???

        I will never recomend to go back to Windows 8.1.My Lumia 640 XL having network freezing problem since last One month and the problem was more cronic as the time was passed.Restarst is the only solution I was visited to Nokia care but they said that there is no issues in smartphone it will be eliminate soon.After two days I got Winndows 10 update.After W 10 update Network freezing issues completly fix but call drop problem.Solution - After Windows 10 update device is looking for second 164 build install it ,then after hard reset is required after hard reset your device is completly copitable with Windows 10 OS (smooth performace) you can easly differentiate between two.Yes Windows 10 battery backup is lesser than the Windows 8.1 but in performance Windows 10 is much much better than Windows 8.1

          Points for windows 10installation.
          1. Installation size is approx 908b
          2. Complete installation takes 6 to7 hours as device will update twiceny using phone update.
          3. Edge browser really very fast. Even I could you say that, The fastest browser than ever.
          4. Candy Crush and whatsapp are little bit slow,but that's not a big issue.
          5. Yes, Windows 10 is faster than Windows 8.1 Lumia denim update 2
          windows user should update to Windows 10 as soon as possible.

            The issue I'm facing after updating to Windows 10 is posting a comment on Facebook. It takes ages to post a small comment. MS should roll out another update to fix all these glitches. Speaker is not as loud as before anymore.

Do not keep any previous apps if you want a smooth working windows 10 mobile. After hard resent download upgrade advisor app. Now check the updates in settings. Download the update. Let the apps update it senf after the installation is done. Now check the updates one again. There is one more update. Download it and install. Do a hardrest once again. Let the apps update and then do a soft reset. You will have very smooth working windows 10 mobile.

                      It's even worse, this is not final version, take whole this year 5 to 10 patches to stabilize. Call drop, worst, email merge into all, and settings most options not operational. What the sh t Microsoft did, doing, will do.

After completing the update I hard reset the phone. Then there is one more update. After this update. I once again hard reset the phone. And then after completion of apps update I did a soft reset.

                          I just upgrade my Microsoft Lumia 640 xl dual simple. It takes about 4 hrs after installing the Upgrade Advisor. It is faster and has nice gui like the desktop version. I am from Lagos, Nigeria.

                              Windows 10 upgrade is a very lengthy process it will takes too much time for installation.Its actually a 'Official Public release' and not a 'Final Version' .

                              There will be new updates on the way, which will add features and have bug fixes.To enjoy bug free Windows 10 experience we have to complete Upgrade to existing OS 8.1 1st then We will get further update.This update is better than the earlier insider Windows 10 preview.Currently I m using 2G data plan and edge browser perform brilliantly.Looks like I m using 3G data.Call drop issues is present With the Window 10 upgrade.

                                      Microsoft officially announces Windows 10 Mobile over-the-air update has begun.

                                      How to update your older Windows Phone to Windows 10 Mobile?

                                      As you may know, Microsoft has finally begun rolling out the over-the-air update for Windows 10 Mobile to a select number of older Windows Phones devices. Here's how you can find out if your phone is eligible and how to download the update if it is actually available for your device.

                                      1. Check the list:

                                      Only a small number of Windows Phones can currently support the Windows 10 Mobile upgrade. Here's the list of phones as it stands right now, but keep in mind that Microsoft will likely update this list in the coming weeks and months.

                                      Lumia 1520
                                      Lumia 930
                                      Lumia 640
                                      Lumia 640XL
                                      Lumia 730
                                      Lumia 735
                                      Lumia 830
                                      Lumia 532
                                      Lumia 535
                                      Lumia 540
                                      Lumia 635 1GB
                                      Lumia 636 1GB
                                      Lumia 638 1GB
                                      Lumia 430
                                      Lumia 435
                                      BLU Win HD w510u,
                                      BLU Win HD LTE x150q,
                                      MCJ Madosma Q501

                                      2. Download and use the Upgrade Advisor app:

                                      If your phone is indeed on the list above, your next step is to download and install Microsoft's Upgrade Advisor app:

                                      After you open the app on your Windows Phone, all you have to do is tap "Next" to see if the Windows 10 Mobile update is available to download.

                                      3. Download the upgrade

                                      After you tap "Done" on the Upgrade Advisor app, the last step is to go to "Settings" on your Windows Phone, then go to the "Phone Update" selection to check again for the Windows 10 Mobile update. You should be able to start downloading the upgrade if it's ready.

                                      By the way, there are actually two separate downloads. One will update the device to build 10586.107. When that download is installed, check for another update for the final Windows 10 Mobile build 10586.164
