WaveUp

<b>WaveUp</b> 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 <b>great</b> Gravity Screen On/Off. I looked for an open-source alternative and just couldn’t find one. So I made it myself!

<b>Features</b>

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

Both are <i>enabled by default</i> but can be turned off in settings.

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

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

<b>Known Issues</b>
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.

<b>Accessibility Services</b>

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

<b>Permissions</b> (yep, quite a few)

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

<b>Uninstalling (Android 8 and older)</b>
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.

<b>Fun fact</b>

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