Android App hang when hide keyboard

[HuyThach]

For input field:
The keyboard of the application is in the Japanese mode, touch on the back button on the bottom left of the device to hide the keyboard. The keyboard is hidden, but if we try to touch on the input field again, no response and after a few seconds, the application is hung.

Please help. Thanks!
I tested on:
- NGUI 3.5.8 and NGUI 3.7.1
- Sony Experia (Android version 4.1.2) and HTC (Android version 4.1.1)

* Updated:
It is even hung in English mode not only Japanese keyboard mode. Please help.

Application hanging points at a Unity problem. What version of Unity are you running?

I have tested on Unity 4.3.4 and Unity 4.5.3

There are currently no known issues about this, so I would need steps to reproduce in a clean scene. Trying input fields works as expected on mobile devices on my end.

It works for me now with the update to Unity 4.5.3p1.
