I installed 10136 on my 920, I am from Malaysia. Here are some quick sharing:
* After 10136 (it came to me as 10.0.12634.0, i think) is installed, there is another update, a shorter one, I am not too sure what it fixes
* No Data Mobile toggle in the notification center! (There have Mobile Hotspot, Connect to Wifi Device, VPN, Quiet Hours), but leaving out Data Mobile toggle?
* As a workaround, I have to pin the data mobile toggle on the home screen.
* Alarm works, but it only alerts you for 5 seconds, there is no prompt to turn it off or snooze, although after you are awake, you can see it in the notification. This will consider to be not functioning to me, it will not wake you up.
* Store Beta works fine. I managed to install Excel Preview, and it works well and looks beautiful.
* Outlook mail now hosts all your email accounts together, I am still not able to find a way to pin my particular email account to the home screen. It remembers all my email accounts after the installation, I do not need to set them up again
* Calendar looks beautiful too and I simply love it
* You will see two PHONE and two SEARCH apps in your list, only one of them is working, the other one just stays there, I do not find a way to remove it
* Camera loads really fast
* Photos app seem to be more organized, but my favorite is gone
* Have not use OneDrive yet
* and I managed to reinstall Whatsapp, There is nothing wrong with it, I was just testing to see if I can uninstall and reinstall it. It works fine without any issue
* Overall, it is a little slow when you do certain things with the phone, sometimes resuming takes longer time
* Battery Saver, the details information is gone. Battery life seems okay, it drops just a tiny bit faster... that takes us to background apps next
* Background apps - everything will be turned ON by default, you have to go and turn some of them off yourself. But I notice the list contains a lot of items without names. I guess that is why it is still a Beta
Thanks.
