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

Premium dimming doesn't dim any darker than the regular device settings (pixel 11). Free portion is great, but did not get what I paid for with premium upgrade. edit post dev response. ye, the thing is there are ways to go darker. the simplest is a black overlay with an opacity slider. the app Darkr offers that on the free tier.

The touch blocking works great and is very responsive. The app needs an option to activate and deactivate it from the notification panel instead of relying on a floating icon that gets in the way during normal use and appears in every screenshot. That's why I can only give it 3 stars.

Edit to dev response. Thank you. It comes up (lock icon) when I press side button, fades, then an instruction comes up (double tap, so no touch block), before that also fades. Just wish it would do none of that, and was only switchable with the power button. BUT, I've revised my stars as this could still work when the rain is pounding my screen and upsetting maps.
