YouTube adding 'black triangle' at bottom right corner of thumbnails for some Android users

As an online video-sharing and social media platform, YouTube has been a pioneer. YouTube’s algorithm is constantly fine-tuned to help users discover the videos they enjoy viewing.

However, the platform is far from perfect, as users have reported issues such as the ‘watch in VR’ option being unavailable for iOS users, the home page displaying a ‘blank screen with no video suggestions,’ and so on.

Some YouTube viewers are currently experiencing a problem where a ‘black triangle’ appears in the bottom right corner of thumbnails for them (1,2,3,4,5,6,7).

Lately, many YouTube users have been expressing their confusion regarding a visual glitch that appears at the bottom right corner of thumbnails and covers the runtime of a video.

This occurs infrequently since sometimes many videos in a sequence are displayed with this glitch, while other times only one of several are displayed with a ‘black triangle’.

This issue appears to have appeared in the last few days and has solely affected Android users.

Yes YouTube, I really love having the video timecode covered up by a black triangle. Not counterintuitive at all 😀

This does not appear to be a thumbnail issue because it occurs at random intervals and can occur for any channel or video.

Although the ‘black triangle’ has no effect on app usability for YouTube users, it is a needless distraction for them.

Hopefully, a patch is released soon that fixes this issue. That said, we’ll keep track of the situation and will post an update if and when there are any further developments regarding the matter.
