A micro SD memory card has been recognized without difficulty and carried out all the necessary settings via a pop-up menu, including almost all apps could move to the SD card, as well as photos and other files.
The Lumia 830 is relatively easy but a bit too wide for my taste, so it is best to operate with two hands.
Restarting I had, then I connected the phone to the charger overnight and turned for more updates left, after that I had experienced no further reboots.
Hardware and operating system harmonize very well. Apps open quickly and the Lumia camera reacts now brisk.
Conclusion: Lumia fans I can recommend the device highly.
