I have 1 chromecast and I use localcast app on a note1 to do as much as it lets with all the extra taps needed.I just happend to be in aUK maplins store and saw something called a prestigio pmd 1 dongle mirroring dongle. My plan is to put a chromecast on every tv but it wont mirror yet. Iam not technically gifted to tell you what the pmd 1 one exactly is but for £29. It plugged in to hdmi micro usb'd to a note 1 plug for power (usb tv port on another tv.) I pressed sreen mirroring on my tab 3.8 and it quick connected the whole of my phone , camera an all.Anything on your pgone is mirrored to the tv, operating system, apps, showbox and all. Im hoping google I/o gives us mirror today but if it doesnt I dont care now id just buy another of these. I dont think thease have any operating system in them (pmd 1) just bit of ram and memory to cast but it works.
