I've been gifted the Samsung A7 tablet (2019) with a 10.1 screen. It is the T500 series but I cannot find a cover for it! The ones in ebay and Amazon make no mention of the T500 series (and if they do, it starts from T510 so I'm not sure I'm selecting the right one for my model. Can someone be an absolute gem and send me a relevant link so I know what to look out for. Thanks in advance!
