Touch Lock Temporarily Blocks Touch Input on Your Phone
Android: If you want someone to read or watch something on your phone, but don’t want them to spy on, Touch Lock can ensure that it can’t do anything by locking the touchscreen.
The app puts a continuous notification in your shadow. Just tap the notification to turn on the lock. Then, when you’re ready to use your phone again, double-tap the barely visible Touch Lock icon to re-enable the touchscreen. Sensory blocking is not the safest thing in the world and is relatively easy to unlock, so you probably won’t use it to keep an adult out of the way who wants to break in. However, in order to prevent children from getting into applications, they should not be, this is a handy tool.
