Always on Display (AOD) for a smartphone means that the screen is partially illuminated and some important information is always displayed on the phone.
It takes advantage of the low power consumption of OLED screens, which not only saves power but also allows you to view time and notifications in real time.
XDA Forum user XJIOP has created an APK application, AOD DoubleTap Mod, which aims to bring the AOD function to OnePlus phones with AMOLED screens but without that function.
Installing the application does not require Root, you only need to download and install normally and then start it through "Accessibility".
AOD DoubleTap Mod is specially developed for OnePlus 7 series, but in theory, OnePlus 6 series, OnePlus 7 series and OnePlus 7T series and other Android phones using AMOLED should be available.
Here is how to enable Always on Display on OnePlus 7 according to XJIOP:
Short description:
Double tap on AOD screen to open lock screen
Description:
This app adds the ability to double tap on AOD screen to open lock screen, where you can view notification text and remove them with a swipe without unlocking the screen.
This app was made exclusively for the OnePlus 7th model and was tested on it, but should work on OnePlus 6 / 6T, 7 / 7T, 7 Pro / 7T Pro models and possibly on other devices with Amoled screens. This app is not tied to this brand of device.
Installation:
1). Activate application "OnePlus AOD DoubleTap Mod"
Settings -> System -> Accessibility -> OnePlus AOD DoubleTap Mod
2). Enable option "Tap the screen to show"
Settings -> Display -> Ambient display -> Tap the screen to show
How it works:
On the off screen, one tap turns on AOD screen, on AOD screen using this app, double tap opens the lock screen.
Double tap of this app works only on AOD screen! This screen is not completely off, it is a screen with a black background on which the clock and notification icons.
