8.10.14192.280 was installed on my Lumia 620 tonight. No problems until now, reboot once to check for problems, all ok.
Some say it is a bit fast but in general, it looks the same. I think the Nokia Camera is faster because I use it everyday and load faster and shoots better. Maybe it is not, but this time was faster. Maybe just me wanting to be faster...
Anyway, update takes more than 10 minutes. So connect it to the socket wall or computer and just wait. After the update, as always, it will update almost every app, so you do need to wait for it to finish and then, restart the phone.
Let's hope the battery is even better as was on the last update, as it almost double the standby time. Before was bad. After these last updates, the line is not flat but l do have the phone to last 2 days with a few calls and email, bluetooth and little more.
So for now, all went well for me. But I need a day or two to test this.
