Its been quite a while the current build 10586.107 has out to insiders and it is also available to production release. We were first to make first impression available to our readers. We are looking closely on the windows 10 mobile builds and checking the performance of the device. So we will suggest to read all the detailed windows 10 mobile coverage on Windows Latest. We are using our Lumia 1020 with current build from quite some time.



We have also done review of the few Lumia phones also running the current build 10586.106,

As done with previous reviews we will divide the review categories below. The complete demo is at the end of the post.

  • First Impression
  • Performance Review
  • Multitasking and App Switching
  • Gaming
  • Camera Review (Especially for Lumia 1020)
  • Final Verdict
  • Demo Video (with the current Windows 10 Mobile Build 10586.107)

First Impression

Before we go ahead you can watch the first impression of build 10586.107 below,

Let me first show you the device configuration,

PLATFORM OS Microsoft Windows Phone 8, upgradeable to v8.1
Chipset Qualcomm MSM8960 Snapdragon S4 Plus
CPU Dual-core 1.5 GHz Krait
GPU Adreno 225
MEMORY Card slot No
Internal 32 GB, 2 GB RAM / 64 GB (Telefonica exclusive)

To a quick view, check the below details to get more information.

In terms of specs its really not an high end phone comparing to today standard that Microsoft has mentioned above, except 2 GB of RAM and a good GPU its an average. During the launch Windows Phone 8 doesn’t support higher processor even though they are available that time.

Now coming back to windows 10 mobile build 10586.107, overall the device does work slower compared to windows phone 8.1, but its not that bad too. I will say, one you start running windows 10 mobile you will like in on 1020 and you will get used to it. The good display and thanks to 2 GB of RAM it does job very well in most of the situation (average camera performance I will say too).0


Performance Review

Before making review of lumia 1020  I did review lots of lumia phone and somehow you will get to know which device is actually working fine with W10M (Windows 10 Mobile). I will say the processor  is more important here to handle the W10M. For a good example you can read Lumia 630 review here.

We opened some of the general day to day usage apps like,

  • WhatsApp
  • Facebook
  • Here Maps
  • Here Drive
  • Adobe Reader
  • One Note
  • Word
  • Excel
  • Skype
  • Microsoft Edge.




they open smooth and also worked very fine. On using the apps to for day to day purpose I had no issues in using them. The performance is fine

Multitasking and App Switching

As the performance is good the app switching and multitasking is great. Due to 2 GB of RAM the lumia 1020 handles heavy multitasking too. Even resuming games likes Asphalt 8 had no issues. They resume perfectly.


Some apps doesn’t show up the original screen when performing app switching.


Overall we had good experience in multitasking too.



When it comes to gaming the real performance of the device shows up. We played many games on Lumia 1020 earlier. In this build we did played only two games,

  • Asphalt 8 Airborne
  • Temple Run 2


We played Asphalt on default setting (Medium Graphics) level. To be honest there are lags. During game start it was more but once the game loaded in to memory there were a few only (2 GB RAM saves lumia 1020 here).  Asphalt experience is also nice. Sensors works smooth and graphics rendering is also good.


Temple Run 2 works very smooth with only 2 drops in our notice, but most people wont even notice that too :). No complaints on that, just works great in single hand also.




Camera Review

If you talk about the Nokia Lumia 1020 and missed to discuss camera review its a shame  to 1020. This is the only Lumia 1020 which still supports Lumia Camera (to handle 34 MP DNG Files).


We used both the Lumia Camera and Windows Camera for taking picture of same object.


Lumia Camera


Windows Camera

Here is our observations,

  • Windows Camera loads faster than Lumia Camera (much faster)
  • Windows Camera stores only once image of effective 34 MP.
  • Both images looks same(Lumia Camera 34 MP and Windows Camera 34 MP )
  • Windows Camera images smaller in size (4.52 MB compared to 7.92 MB of Lumia Camera 34 MP)
  • Lumia Camera stores two images
    • 5 MP
    • 34 MP (DNG)


I have uploaded the original photos in case you want to check those sample.

I will recommend to use Windows Camera

Final Verdict

Since the lumia 1020 doesn’t support SD card removable battery, make sure to take proper backup if you are planning to upgrade. As said earlier you will not get disappoint.

    Hi. Have you noticed in the display, when you scroll a text e/or photos, if, putting the 1020 in landscape position, a portion of the screen (left side) freezes or hangs? This happens only in W10Mobile version. When in WP8.1 this issue do not happens.
