I buyed a USB-C to HDMI device and it didnt work, so i thought the problem is the device and tryed to get a refund.

I have no other device capable of testing it and i searched in the entire Internet about it but found nothing.

I found something about HML and my device does not support it, but some people said that the HDMI works even without the device supporting HML.

Samsung flagship devices support it - not all. Check the lists at mhltech.org and everybodywiki.com. I cannot find the A21s or its model alias SM-A217F there.
