YouTube v4.0.23 Android Apk App

Requirements: Android 3.2+ (HC/ICS/JB)
Overview:

 Keep up with your favorite YouTube channels and access the world’s videos anywhere with the official YouTube app for Android.
 I saw some threads floating around about youtube 720p playback, and I really always wanted that too for a long time.
 But I was stupid enough not to even try it.
 I did try now and, yep, I got it working!

 What's in this version:
 Android 4.0+ devices: v.4.0
 * Nexus Q support
 * Bugfixes

 How I installed it:
 • Removed /system/app/YouTube.apk (you need a rooted device for this step! If your device is not rooted, try ignoring this step, but installation may not possible.)
 • If YouTube is still there, just go into its app info tab and tap "Remove installed updates" or something, then "Force stop".
 • Install my APK!
 • Of course, your device must be capable of 720p video decoding!
