Good day. I'm using an X7 with the official Kitkat 250 firmware and am having problems with the YouTube app; not with all videos, but for a relatively large number of them sound plays, but video is black. As an example, I've not been able to get the following video to play in the YouTube app (newest, currently version 12.32.60) : Would anyone be able to confirm or deny the issue and if so, could you be explicit about the firmware version you're on? Note, the above video does play in Firefox running on the X7; it's only the YouTube app that has the problem. Don't know how to provide a "YouTube-App link", if that's even possible. I do not myself use YouTube but a visiting child runs into the issue constantly. I recently upgraded my home network to wired from wireless and thought that would be it; i.e., YouTube-app auto-selecting a higher quality that the X7 then trips over, but actually unplugging ethernet and re-connecting via WiFi doesn't help; the video still doesn't play (including after rebooting the X7). I also tried all HLS configuration options in the Android settings and none of them make a difference. My connection speed is approximately 70 Mbps over wired; as said though, it doesn't work to switch back to WiFi, nor to set the video to for example 240p. Can anyone help? You'd be doing the mentioned child a big favor. I believe this started only recently, but am not myself sure. [EDIT] I see that my youtube-link has auto-turned itself into an embedded video, but please note, I'm only after a report for the YouTube app. I'm sure that the video will play through browsers here. The title of the video is "When costumer refuses to pay"; if someone could search for it in the YouTube app on X7 and try it, that would be great.
