UIInput Blocks UI Thread on Android App becomes non responsive

[mstar]

After I upgraded my Unity Pro to 4.6.1p3, my UIInput no longer works. Once you click on the input field, and type some characters in the on screen keyboard and click OK to dismiss the keyboard, app will become non-responsive. It seems UIInput is blocking UI thread. This only happen after I upgraded Unity. I have created a separate test scene with just one simple text input prefab on stage (the prefab from NGUI package). The issue remains the same. Also this bug only happens on Android, works fine on iOS
Can anyone help?
Thanks,
Chris

I suggest reporting it to Unity, not to me. If it works on platform X, & and Z but not on W, it's always Unity bug. Especially if it worked in 4.6.0 and doesn't work in 4.6.1.
