is it possible to watch netflix 4k from my phone. netflix are showing films in uhd 4k. now can i get mini micro to hdmi and plug it in my lg 4k televison its not a smart tv just 4k with Ethernet in the back as there is a few streaming channels. or could i mirror cast the phone to a dongle and do it that way. plus i was led to believe that youtube show 4k stuff but i have not come across any yet. also i use Bluetooth headphones but when im listening to my playlist on youtube i have to leave my case open if i close it youtube goes of and the clock comes on its the magic circle case, i dont know if there is a setting on the phone. when playing music from sdcard or my wd 2tb cloud i can close the case and it still plays, any advice please.
