I have had a number of hardware and software issues in the 6 days I've owned the device. I'll be exchanging mine on Friday. I'm really hoping I got a lemon, but there are so many issues that I'm very skeptical, and very much missing my Surface 2.
1. 64gb memory card would only hold saved items for a few hours, then require a reformat. It's the same card I used in my Surface Pro, and Surface 2, so I know it's fine. I just tried a 32gb card today, so far so good but still disappointing.
2. Graphical glitches in 3d games such as Dungeon Hunter 4 and Asphalt 8. They both look fine on my dad's Surface RT. Hopefully it's immature drivers.
3. Camera no longer works. I snap a photo, the app crashes, and the green light stays on for about 5 minutes. The tablet still works during this time. I tried a full reset today but still no luck here.
4. The sim tray no longer sits flush on the top, but rather sticks out about 1/16 of an inch. Not a big deal, but a concern.
5. Yellow display: maybe it's been like this all along, but the whites definitely have a yellow tint.
6. I did another full reset to attempt to fix the camera issue, and it's been on the Nokia logo with spinning circle for a few hours now (Lumia 900/920 flashbacks...)
7. I can't get any devices to connect via the micro USB port.
Like I said, I really hope I have a lemon. I don't even have the sleep issue so many seem to be relating. I have to say, this tablet feels like a gigantic step down in class from the Surface Pro, and Surface 2.
