Always on Screen is an Android application by FayaX that allows you to keep your phone screen on at all times or activate it by waving your hand over the proximity sensor. With this app, you can easily check the time, date, and notifications without having to unlock your phone or press any buttons.

One of the best things about Always on Screen is its extensive customization options. You can choose different clocks, calendars, and fonts, as well as resize almost all elements of the screen. The app also allows you to display notifications and choose which apps you want to receive notifications from. Additionally, you can show the battery percentage and select which information you want to see on the screen.

Another notable feature of Always on Screen is its ability to avoid AMOLED displays burn-in by auto-moving the screen. The app also has a pocket mode, which disables the app when it's in your pocket, and an auto-disable feature that turns off the app depending on the battery percentage. There are also gestures available, and you can stop the app and unlock your phone with your fingerprint.

Overall, Always on Screen is an excellent app for those who want to keep their phone screen always on or easily check notifications without unlocking their phone. With its extensive customization options and useful features, it's definitely worth trying out.
