    I did just download Unity 5.6.0f3. Problem still exists.

    Vuforia ArCamera and simple InputField are enough to reproduce this bug.

    I just tested a simple project with Vuforia and a single InputField.
    On android when i add text multiple times to the input field, the camera feed is going slower and slower.

    Tested on Unity 5.6.0b7 : NOT FIXED although the current bug status is fixed in Unity 5.6.0. and with only one input field !

    Tested on Unity 5.5.0f3 : NOT FIXED

    Tested on Unity 5.3.6 : WORKING AS EXPECTED

    For anyone still experiencing this issue, I found using this plugin overcame the Android keyboard disrupting the camera feed:

    The same as the previous comment. After one input field was activated, the camera seems to be working, but after activating multiple input fields still cause the camera feed buggy.

    The bug is gone if there is only 1 input field. However, having multiple input field will cause this issue again.

    This bug is still present in 5.6 beta, I just tested our app and the keyboard still kills the camera feed on android.

    This also happens when native pop ups come up like NativeToolKit stuff.
    5.5.0f3 still bugged.
