ASUS Miracast dongle Tool

I can't connect my phone with my samsung smart tv. Previously on jelly bean 4.3 works perfectly(mirror cast). Now on kitkat 4.4 i can't connect. (playto) is not working, connection established for a few seconds after some time not found error kindly fix the bug

Even when my zenfone 5 detects my LG smart tv and the message "connected" appears on the tv screen, the latter remains blank and doesn't mirror the phone. It takes a lot of tries and time to finally get the screen casted. Please fix this

It's good because it keeps the firmware updated. I don't where to ask, is there any support for upgrading OS of some Lite version of your phones, mine is Zenfone 5 Lite, the Zenfone 5 get the Lollipop update amd maybe getting later versions, what about the Lite? Is it stuck on KitKat?
