Ok, so I have had my VS rDNA 40 for about 2 weeks now and it is performing flawlessly. Tonight was a fairly cold night (0-1.5 degrees C) and I was spending a bit of time out in the garage. I set my VS down for a few minutes. When I came back to it, it performed as expected, but the screen was totally black. After a few minutes, it started lighting up again, but was garbled. Still vaping as usual. After quite a few minutes in the car (warmer temperatures), the screen was back to normal. I have never seen this problem before. Should I send it back in, or is that just a side-effect from cold weather?
