Hiding notifications on the lock screen Xiaomi Redmi Note 9: the full guide

Why Blocked Notifications Can Be a Dangerous Data Leak

The lock screen of the Xiaomi Redmi Note 9 is not just a protection against accidental clicks, but also a potential “loophole” for prying eyes. Imagine a situation: you leave your phone on the table in a cafe, and the screen shows an SMS from the bank with a confirmation code or a message from the messenger with confidential information. Even if the device is blocked, the content of the notifications can be read by anyone who is nearby.

Xiaomi’s MIUI firmware (even in the current Redmi Note 9 versions) displays notification text on the lock screen by default, ostensibly for user convenience. However, this convenience turns into a privacy risk. This is especially critical for owners who use the phone in a corporate environment or store sensitive data on it. Fortunately, the system provides flexible tools to manage the display of notifications, but they are hidden in non-obvious settings sections.

In this article, we’ll look at all the ways you can hide notifications on lock, from complete shutdown to selective settings for individual applications, and how to get around common bugs (such as when settings are reset after a MIUI update) and what to do if standard methods don’t work.

Method 1: Completely disabling notifications on the lock screen

4. Activate the option to Do not show notifications (in some versions of firmware it may be called Hide content or Disable).
5. Confirm the changes if the system requests a password or pattern lock.

Method 2: Hiding the contents of notifications (without completely disabling)

Special cases: Call notifications and SMS

Missed calls and SMS are handled in a special way by the system, and even if you have completely disabled the notifications on the lock, the information about the calls can still slip, which is because MIUI classifies them as "critical" notifications.
