Ugoos AM6B+ broken HEVC/H.265 video engine

Hi,

I recently received my Ugoos AM6B+, and I think it has a broken video engine. When I play any HEVC/H.265 content, the video is purple-ish, pinkish, and there are visual artifacts on the screen. I tested with multiple TVs, and multiple HDMI cables, and the symptom is the same on both Android and CE. Playing H.264 or VP9 content is working as expected. I wonder if re-flash (of the Ugoos Android software) would solve it? How it can be, that only HEVC/H.265 is broken?

Can somebody confirm, that such issue can happen, that amlogic hardware decoder or the VPU ( Advanced Video Engine Gen10) is broken, and if it is a hardware error? If it is confirmed, I will return the device and ask for a replacement. Thanks for the hints.

Just to update - it was a faulty unit. I sent back to AliExpress, and got refund.
