I have purchased several of these testers which appear to be made by the same company. From the lowest price to over $600 they all seem to share the same 9800 or 8500 main processor. They all seem to lose cameras in multi-view and any attempt to start multi-view after that crashes and returns to the main menu . These devices are overpriced due to the inconsistent performance they offer. I work with them two or three years ago. Screens get better, but performance remains the same. Camera, and in other cases just clicks.
