No, so far I haven’t noticed any screen separation issue. This is also my first handheld console and I’m really happy with it, I wouldn’t have thought it myself. However, I ordered from Amazon (in Germany) for far too much money, only I found out too late. But maybe better that way than if I had to wait a long time for it. It’s really great to be able to play your old favorite games from anywhere. The only “issue” is: I suspect that the emulator apps that come with it are pirated. You don’t get any updates via the Google Playstore. But I uninstalled the ones I really use and then bought them in the Playstore.
