Greeting Wandalorians & Wand Wizards! I was having screen flicking and sometime blackscreen when Wand updated last time,especially on the videos in app, I finally figured out that it was a newer Nvidia update to the Graphics Driver I needed and fixed the problem, I hope this may help anyone else that might be experiencing this. I wanted to say Thank you for the Great work you are doing on this product, its been very fun playing Old & new games, so much i didn't hesitate to go Pro. Thank You Wand Team!
