In our world, smartphones have replaced many things. Most people are happy with this change because they can't live a day without one. One of the most popular smartphone brands in the world is OnePlus. People love the accessibility of these phones, which leads to a lot of sales. One downside is that many people have experienced an issue with their OnePlus 6Ts' notification light. People accustomed to using the light may find it irritating that it doesn't work anymore. A guy came up with a solution to this problem, which eventually led to the creation of NotifyBuddy— an app that has helped millions of people. Advertisement

NotifyBuddy originally used lights on the phone to notify the user of incoming messages or notifications. However, they stopped functioning on most phones and are only repairable at specialized phone repair centers. By creating an app, he eliminates the problem naturally since it eliminates the need for a software. It doesn't need to be installed on your phone physically. It functions just as well as a physical indicator light. Unlike the default notification light, it provides additional options. You only need to download a specific app and use it like any other app. That’s because the app is very clever — it eliminates the need for users to pay for phone services to fix an issue with their device. Disabling the ambient display and any battery-saving features in the phone allows you to use it. You can also select which apps can use the display through a menu option.

This light notification app was created for just one specific function, but it has many additional features that make it a very useful app. We'll discuss all of these in a moment. Smartphones come with a notification light that cycles through different colors and animations. However, users lack any way to change the light's effects or cycle. This is because the notification light is built into the phone's operating system. NotifyBuddy lets you change the LED light animation time from one blink to ten. This means you can make the LED light take anywhere from 1 to 10 seconds to blink one time. Advertisement You can change the color of NotifyBuddy's LEDs at any time. This is thanks to the inclusion of a color wheel. You can choose from different LED colors, including red for greater visibility. Alternatively, you can use white LEDs as is by default. With NotifyBuddy installed on a smartphone, users can adjust the position of notification lights anywhere on the screen. This app makes it possible to display lights at the top, bottom, left or right corner of a smartphone's display. Alternatively, users can adjust lights to appear in the center. With an app, users can adjust the size of their LED notifications to small or large. This is helpful for people who have trouble seeing. They no longer have to miss important notifications because of this change! With the premium version of this app, you can pause its functionality for a specific amount of time. This is one of the unique features of this program, and it's not shared with the free version. This app is completely free to use, download and wear! It works with every Android phone and the OnePlus 6T.

Getting started with the app is a breeze. After only a few periods of use, users learn how to efficiently utilize the app's features. We also offer helpful guidance on how to properly use the app for optimal results. You can change the appearance of your phone by deciding which apps you want to notify you about. Propose applying notification permissions to allow an LED light to blink on and off when selected apps notify you. This will help users quickly check their phones when they have important information. Notifications can be configured in a number of ways, including color, size, and placement of the LED light. They can also be configured to notify users about important news, or even notify them when they get a new message. This makes the phone easier to use for users because it saves them time by notifying them about important news. This program offers many customizable features.

To keep apps running longer, don't forget to grant required permissions to our apps. Additionally, grant access to LED lights so that our apps can notify the user. You need to choose the color scheme for the LED lights that will display your chosen application. It's critical to note when you have successfully chosen a color scheme— the announcement LED lights will turn that color. With the corresponding notification LED light color, the name text will be changed to equivalent colors so users can easily recognize it. MIUI 11 was released with several new features. One of these is that users should make sure the "Autostart" option is checked in the application's settings. Checking this box allows apps to display notifications when the phone's screen is locked, which allows users to see all LED notifications at once. Additionally, users should check the "Show on lock screen" option to grant that permission. Doing so allows MIUI 11 apps to display notifications when the phone's screen is locked and unlocks new features for these programs.

New features make our app more loved by its users. We continue to update our app to meet the needs of our users. One of the reasons folks love our app is because of the LED notifications. No other apps have this feature. ———

So I was annoyed not having an LED notification light on OnePlus 6T so I tried to make one of my own.
As OP6T has amoled display whenever a desired notification comes the app brings in a black screen with notification LED looking animation.

Though this is tested on OP6T, it should be working for most Android Oreo and later phones.

To use it:
Install App.
Disable Ambient Display and any battery optimisation for the app.
Give notification access permission.
Select apps you want notifications for, by choosing a color (Only apps you set a color to enables LEDs).
Note: On successfully selecting a color for an app the text in which the App name is written should change to that color
Thats it.
