Touch Blocker: Disable Screen

Nightly Nexus

About this app

Touch Blocker can intercept touches, taps, swipes, gestures, and any other input on your screen, so you can leave your screen on without worrying about accidental input.

Listen to YouTube with your phone in your pocket. Leave a chart open on desk tablet.

Touch Blocker is the only app I know of that correctly and fully intercepts screen input to lock your screen on and avoid swipes, system navigation, and opening the notification shade.

Note that Touch Blocker uses the Accessibility APIs in Android to display a screen overlay. Touch Blocker will ask for this permission in the system settings when you open Touch Blocker. Touch Blocker does not collect or store any data and only uses this permission to display the overlay as necessary to function.

Touch Blocker is open source.

P.S. for power users:
Other apps (like Tasker) can broadcast locking, unlocking, and toggling Toch Blocker via these broadcast actions:
com.nightlynexus.touchblocker.ACTION_START_BLOCKING_TOUCHES
com.nightlynexus.touchblocker.ACTION_END_BLOCKING_TOUCHES

Ratings and reviews

Great app but it could use some improvements. The onscreen lock/unlock icon needs to be resizable or have a few size options and the icon is hard to tell whether it's locked or not. The image needs to be reworked. APP has been updated and addresses all the above issues. Excellent work!

Perfection. Tried multiple apps but for some reason none of them worked properly. I wanted to lock the touch screen so I could trace over a few pictures and this worked perfectly. So simple to use, responds to the double tap immediately, can't fault it. Only improvement I can think of would be an option to use a pattern or pin to unlock instead of just clicking the icon

I like that in order to unblock your screen, you have to tap twice. I think that's smart! This app works pretty well in general and, to be honest, the only thing I don't like is that I have to go to settings again if I close the app. Maybe that's just something that happens on my phone though and it isn't an actual problem. I'm very satisfied with Touch Blocker! :)

What’s new

New unlocked icon for better differentiating visibility.

New Free Feature: Custom sizes for the floating lock button.

Also, Touch Blocker now works on older devices, too.
