Yes, in UDOO you can't take a screenshot using buttons. You need an app like this one: https://play.google.com/store/apps/details?id=com.icecoldapps.screenshotultimate
Hi, Just tried the proposed app (screenshotultimate) on Udoo Neo running 5.1.1. I cannot take a screenshot using any of the available methods. The Capture method automatic detection report no possibility found, and the Manual method is giving more success. Does anyone already succeeded to take screenshot on UdooNeo running Android ? Regards, Jeremy.
