Build 14393.3 Installation Experience:

The Installation experience has been smooth for us in case of the Build 14393.3. On three of our devices it took around 35-40 minutes for the build to get downloaded, installed, data migrated and the devices getting up and running. In case it takes too much time for you try a soft reset or plug-in the phone and it may work finally. You can refer to our common issues and errors fixing guide for more.

You will be usually notified for a restart when the download has completed in background. You can check our tutorial on how to prepare for upgrade to Windows 10 Mobile.

Build 14393.3 Hands-on Impressions (Performance, Multitasking, Gaming, Battery Life & more):

Here is what you could notice during our hands-on with Build 14393.3,

  • The Build 14393.3 runs very smoothly and impresses with its responsiveness all around.
  • It packs mainly fixes and improvements and is breeze during normal daily smartphone tasks like start-screen navigation, apps list scrolling, opening and closing of settings, handling calls, texts, Mails and more.
  • Mobile Data and WiFi connections work fine on our devices
  • Store works appreciably fast and is much better now. In fact the issues with app re-installations are nearly gone
  • Native apps like Maps, Camera, Outlook Mail & Calendar etc work fine. Sharing works flawlessly.
  • Microsoft Edge has kept improving with every build. It loads pages faster and zooming, panning etc work appreciably well.
  • Video streaming and playing also works fine without any issue like flickering faced on very early builds and we have demoed it too.
  • Gaming also works fine and with Build 14393.3 we have demoed with two games open at the same time. Needless to say that games optimized for Windows 10 Mobile still offer better experience
  • Multitasking for apps works impressively and apps resume really fast from background. Apps don’t crash in background while multitasking
  • Battery Life seems quite good so far during our hands-on usage of the Build. The Battery discharge rate seems to be the one of the lowest so far.

Major Bug & Issues:

  • Microsoft needs to work with developers to get the Windows 10 Mobile optimized version of the games in the store, as optimization seems to be the culprit while multitasking with older games. Windows 10 UWP games resume instantly from background.
  • Bluetooth functionality needs a UI and connectivity overhaul. Fixes for known Bluetooth issues too. Surprisingly Microsoft ignored it in Build 14393.3.

So, Build 14393.3 really seems to be a solid build so far and in terms of performance, multitasking and overall polish it seems very close to earning a daily driver status for itself. Microsoft may release several cumulative builds for Build 14393 before making it the public release or Anniversary update.

We also want to make it clear that it is our hands-on experience with the build and your experience may vary and may be better or worse than ours. We recommend hard reset, if you are facing lots of issues. You can read our guide to fix commonly known Windows 10 Mobile upgrade, installation and usability issues.
