Basics

Android 15's Sensitive Notifications is a feature that offers increased privacy by screening the specifics of certain alerts on your device when the screen locks. This guide will shed light on its implications for users and how to handle these preferences.

A Deep Dive into Sensitive Notifications

Sensitive Notifications serve as a shield for your private information against unauthorized access by users or applications. By activating this feature, notification details such as emails, text messages, and sensitive content get hidden when your screen is locked, providing security for personal messages, one-time passwords (OTPs), and other confidential data.

Navigating Sensitive Notifications Settings

Sensitive Notifications can be managed using your Android 15 device's settings. Below are the necessary steps:

Begin by launching your device's Settings app. From the options available, select "Notifications". This will direct you to a section where you can find "Sensitive Notifications" or "Enhanced Notifications". At this point, you can choose to enable or disable this setting based on what suits you. Once activated, the system conceals sensitive material from the lock screen.  Many devices have a setting called "Sensitive Notifications." This setting, when enabled, allows details to be displayed on your lock screen. It might seem that turning this toggle off would display these details, but actually, it does the opposite by hiding them.

Users have the ability to enable or disable the Sensitive Notifications feature overall, but they do not have the option to alter the visibility settings for individual notifications as that is determined by the application developers.

Tips and Hints

For certain applications to present sensitive notifications, you might need to grant special permissions. This can be done in the app settings. Be aware of notification access if you're using interconnected devices such as smartwatches and ensure they have essential permissions for reading notifications. For optimal security, keep your device current with the latest safety patches.

Advantages of Using Sensitive Notifications

Sensitive Notifications maintains your privacy by guarding personal information from unauthorized exposure. It thwarts potentially harmful apps from stealing private information like OTPs. Above all, it puts you in control of the data displayed on your lock screen.

When you make use of this feature, your privacy and security are boosted, securing sensitive data even when your device is inactive.

Insights for App Developers on Setting Notification Visibility

App developers can classify notifications based on their sensitivity. This is accomplished by defining certain settings in their code, marking notifications as public, private, or sensitive:

Developers can sort notifications into categories or channels. Each category has distinct importance and visibility parameters. Public notifications have full visibility on the lock screen, private notifications only reveal basic information, like the app name until the device is unlocked while sensitive notifications only show the notification symbol on the locked screen.

Developers use the setVisibility() method in the NotificationCompat.Builder class to adjust the visibility of a notification. Feature visibility levels include Public, Private, and Secret modes. While users can enable or disable the Sensitive Notifications feature in general, they cannot change the visibility settings of individual notifications as specified by the app developers. Hence, a notification marked as sensitive by the developer will always be counted as such on a locked screen.

The Impact of Sensitive Notifications on Interconnected Devices

When you've enabled Sensitive Notifications, not only the phone but also the associated smart devices such as watches, tablets, and smart displays, hide the details of these notifications. For instance, if you get a sensitive alert, your smartwatch won't display the content; you might only view the app icon or a common notification alert.

Much like with smartwatches, other connected instruments will also prevent sensitive notifications from being seen. This means you'll have to unlock your phone to view the complete information.
