Thanks to @neocyke for your useful tips on APKs downloads. Saved me a couple of hundreds as I just want some light viewing on Youtube and other apps. You are da man!
Also thanks to @ffxmadman for the tips on Youtube TV version 1.2.7 works well for the Hypptv box. The versions 1.3.xx and above have problem with the tiling as per mentioned.

Thanks ya all for sharing!
