YouTube for Android had been updated, and can now play HD videos on Gingerbread and Froyo (2.3 and 2.2) devices as well. While the feature is now there, only capable phone will be able to actually play videos in HD.
Many Android users are still using Gingerbread and Froyo, so this update should be relevant and welcome for a fair number of users. If you’re not sure whether you screen has the right resolution, the best option in this case will be to simply get the new YouTube update on your device and see if can stream HD videos.
Don’t confuse HQ (high quality) with HD. Even before this update, your phone was capable of showing YouTube videos in HQ. This new update will hopefully enable HD video streaming, which is quite different. The update should work on devices such as the Samsung Galaxy Nexus and Galaxy Note, HTC Rezound, Motorola Droid Razr and more (i.e., newer devices). If you can’t see the update on your device, you can head over to the Android Market and download it manually.
Let us know in the comments if you’ve managed to get HD streaming, and on which devices.
