Some years ago we bought a Tesco Hudl (the first one, not a Hudl 2). It features a small Tesco button on the navigation bar. Its presence on the bar is not an issue but there is a problem where the device periodically starts registering presses to this button, opening and closing the Tesco website every few seconds. The only way to stop this at present is to lock the screen using the power button, wait a few seconds, then resume normal use. The manufacturers were clearly aware of screen issues, as one of the software updates that rolled out claimed to address this and did help. The device is so old, it would make no economic sense to physically repair but disabling the button that registers the click would make the user experience much better.
Yesterday I looked around for ways to disable or remove this button. It seems that some years ago people on MoDaCo created a custom firmware for the Hudl that did not have the button. I tried to download the binary last night and the server seemed to through errors, so I assume it does not have the file any more. Further to this the version of firmware this mod seems to apply to the more recent version installed on the Hudl. The Hudl is running Android 4.2.2 and a later ROM version than the 20130923 specified for this alternative image.
A few people also suggesting using some software to remove or disable the soft button without loading a new ROM image. I have managed to ''root'' the Hudl and install the Xposed framework but I have not been able to find a tool that would let me modify the [ T ] softbutton. I have been able to change the style of the other Icons (which might be a welcome relief to my partner as she hates the Lollipop NavBar icons on her Nexus 4), but not alter the Tesco icon.
Please can someone provide some simple instructions of how to remove or disable this NavBar soft button? As I have mentioned it is a rooted Hudl 1, running the latest over-the-air firmware.
