    Still present in 2017.3.1f1. Only solution is to minimize the app and re-open.

    Still not fixed in Unity2017.2.0f3
    Hope this will get a fix soon even though this is set to 'Won't Fix'...
    Is there an older version with Vuforia that does work, so i can make a working android build without lag?

    I don't know why this issue is not being fixed. While Unity has released new versions with new features we are still stuck with the old version because of this issue. This is very frustrating. Request the Unity and Vuforia team to fix it as soon as possible.

    cannot upgrade my project because of this.
    Works fine if we have one input field but lags with 2 or more.

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

    It's very easy to use, just attach the script to your inputfield game object and attach the pluginmsghandler script to a game object in your scene. It's all opensource and fully customisable.

    Works with Vuforia 4, I have not tested with other versions.

    I'm currently using 5.4.3f1 and facing the same issue.

    After searching around for solutions, it seems the app loses focus when on-screen keyboard is fired up. Attempting to manually call these functions proved unsuccessful as the camera feed still suffers from extreme lag. A workaround was to minimize the app and re-open - either with the Home or Menu buttons.
