    Before this build, my almost 2-year lumia 730’s uptime was a shame, the absolute record was below 3 days (reached 4 months ago).
    Now with this build i reached over 15 days uptime, the phone worked perfectly, without any problems, I had no reason to restart.
    Now i had to restart for new update 10.0.14393.321 I hope it won’t fuck up this amazing performance.

    How about Lumia 535?

  • Pedro Weekes

    Still has black screen unlock bug!!!

      try disabling the auto brightness and set a fixed level of your choosing.
      this seems to have fixed the issue for me, so far.

    So far _very_ good and stable on my Lumia 950. Fixed many issues I had on prior .67 production release… Including fixing many issues that were not listed in the official changelog.

    Finally starting to feel like a more polished OS! First time I can honestly say that since release of W10m last year. W10m onward and upward!

    I suspect this may also be the real reason why Microsoft has waited to release a Surface phone. Releasing a Surface Phone to a large audience with the insanity that has been w10m to this point would have been a huge mistake.

    Looking forward to Redstone 2 and Surface Phone!

    Looks a good update but still has a WiFi issue on the Lumia 930. You can see the SSID’s but it gives an error message when you try to connect, also sometimes you can connect to an SSID but it doesn’t give you internet access. Both are fixed by restarting the phone

      Very disgusting as always there is update and then also always there is heating problem and battery ? draining issue .lumia950xl is one of the wrost phone of the world never just buy or you will regret ,whole life

        They really need to get their act together. I recommend software, communications and phones to large multi nationals and currently I would never advice them to have any Windows 10 Phone based product – not even phones like the Elite from HP – with the quality of operating system that Microsoft are shipping.
