I love Chromecast but a few issues keep making me sad. 1. Casting a photo from Photos app, pressing Android back button makes the TV screen go black. Have to remember to swipe left or right instead, or use in-app back button. 2. Photos on 4k Cast-enabled TV are shown in horrendous quality. It's definitely not 4k and compressed as hell with contrast loss. Same for videos. There used to be a ton of race conditions in YouTube TV app but those are thankfully fixed.
