WaveUp

About this app

WaveUp wakes up your phone—switches the screen on—when you wave over the proximity sensor.

I built this app because I got tired of pressing the power button just to check the time (a surprisingly frequent habit). Inspired by the great Gravity Screen On/Off. I looked for an open-source alternative and just couldn’t find one. So I made it myself!

Features

▸ Wave mode: Turns the screen on when you wave over the proximity sensor.
▸ Pocket mode: Turns the screen on when you pull your phone out of a pocket or bag.

Both are enabled by default but can be turned off in settings.

▸ Screen lock: cover the sensor for a second (or your chosen time) and the phone locks. Off by default, but easy to enable.

Wait, what's a proximity sensor?
It’s that invisible little thing near your phone’s earpiece that turns off the screen when you’re on a call.

Known Issues
Some phones keep the CPU running while listening to the proximity sensor and this drains battery (blame your phone, not me). Most phones don’t, so battery use is minimal.

Accessibility Services

▸ Purpose: Used to lock the screen on Android 9+
▸ Privacy: Used only for this, no data collected
▸ Scope: Doesn’t spy, just locks

Permissions (yep, quite a few)

▸ WAKE_LOCK – turn on the screen
▸ RECEIVE_BOOT_COMPLETED – auto-start on boot
▸ READ_PHONE_STATE – pause during calls
▸ BLUETOOTH / CONNECT – avoid pausing when on a Bluetooth call
▸ IGNORE_BATTERY_OPTIMIZATIONS etc. – stay alive in the background
▸ FORCE_LOCK – lock device (Android 8 and below)
▸ ACCESSIBILITY_SERVICE – lock device (Android 9+)
▸ DELETE_PACKAGES – let the app uninstall itself if needed

Uninstalling (Android 8 and older)
WaveUp uses Device Admin permissions, so it won’t uninstall the usual way. Use the 'Uninstall WaveUp' button in the app to remove it properly.

Fun fact

This is my first Android app and my first open-source contribution! I'd love your feedback or help—especially if you're into translations or just enjoy tinkering.
Open source rocks!

Ratings and reviews

I really appreciate your effort. i tried many apps and this one is more better than those. but one think that is irritating me is that every time i need to enter password to unlock mobile i already set in mobile setting that lock my device after 10 or 30 minute so that i don't need to enter many time password but when i used your app i have to unlock my mobile by every time with password. my mobile power botton is broken. IF YOU INCLUDE THAT ONLY SCREEN GOES OFF AND ON without locked the device!

The button that turns on my phone was damaged, which caused trouble in using it, but with the help of this app, the phone is easy to use. It has come as a boon for old phones. This app is actually very usefull.

If you want to lock your screen off then it is for you. its not about phone off/on. nor did screen on.
