Ok so I downloaded photos a lot in in huge succession up to the hundreds and it takes a while for them to show up ok my gallery. Then after a while they will show up, but sometimes they just disappear with the only trace being my download to prove I downloaded it and I'm not crazy. Though when I tap on the file in the downloads the file just disappear as soon as I take it. I can't find it in file manager or anywhere. There just gone. But its not all my photos is just the one I downloaded that day. I've tried recovery apps but that just brings back photos I've deleted. Someone please help. I'm at the point of just full resetting my phone. I have a zte Max pro btw. Idk if that helps.
