WaveUp Fortune Cookies

WaveUp Fortune Cookies wakes up your phone — switches the screen on — when you wave over the proximity sensor. As a plus, for this pro version, you get some cool cookie sayings.
It's mostly a way for you to show your appreciation for my work.

Please check out WaveUp before you buy this app. The waving functionality remains the same. With the pro version, you get the coolness of the fortune cookies :)

Here is the original WaveUp description:

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 Service

WaveUp uses the AccessibilityService API for one purpose only: to turn off the screen when you cover the proximity sensor. It does not read screen content and does not collect or share any data.

The accessibility service is optional. It is only needed if you enable the screen-lock feature — if you don't, WaveUp never uses it.

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!
