Reader request: Icon based unlock system in Tasker

Got another Tasker video tutorial based on a reader request. The challenge this time is to create a lock screen that requires you to tap a series of discreet icons to unlock the screen, rather than use the traditional PIN/pattern unlock system. The video shows how to create the basic system, which can be expanded upon however you want.

The slowness issue I mention in the video can also be solved by adding a Wait action before the Variable Set actions for icons 2, 3, 4. The down side of this is that there will be a delay from you tap the last icon to the system actually unlocks as everything catches up. The method used in the video is quicker if your inherent code input isn’t too fast, so both have pros and cons. If you have any suggestions for work arounds to this issue, post a comment below.

Disclaimer: You need to be careful when dealing with the System Lock action, especially when it’s tied to a %WIN refresh! I mention this again and again in the video, but I can’t emphasize this enough. You use this system at your own risk. Also, as you can see, the system works with my device/ROM/Tasker version combination. If it doesn’t work with yours, there’s no way for me to know why.

    Hello,

    When I create a scene, I set the background color to BLACK. Now when I add buttons to the scene, how can I make them black color? The idea is to make the buttons “invisible” if you know what I mean. I only see an option to change the label color, nothing for button background color.

    Any idea?

      Use blank images or text elements with transparent backgrounds. Tasker has a blank image in the built in icons. You can also use that to add invisible icons to WL

    Ended up using a image that is all black. It works. But still would like to know whether it is possible to change button background color.

    What is the easiest way to display an image on the screen?
    I have a 720×1280 image that I would like to display on the screen of my S3, which has the same resolution. I played around with scene+image element but it is a pain in the butt to get the exact 720×1280 resolution for both the scene and image, if it is possible at all. Must be a better way to simply display an image that covers the whole screen….please help!
