Google Talk that bundle with Samsung Galaxy S II does not have video chat function. I keep seeing people asking for it. Personally, I don’t use Google Talk because not much of my friends are using Google Talk. Anyway, here is the Google Talk 1.3 apk with voice and video chat support. By the way, root access is required.
How to install Google Talk 1.3 with voice and video chat support? Copy libtalk_jni.so to /system/lib using ES File Explorer first. Then install Talk2.apk. That’s all.
Download Google Talk v1.3 apk for Android here.
