Lock screen customization is an important aspect of a modern smartphone and the Redmi Note 4 offers a wide range of options. In this tutorial, you’ll learn how to change your lock screen wallpaper, disable notifications, and change the timeout interval.

Set Lock Screen Wallpaper
Like many other smartphones nowadays, the Redmi Note 4 allows you to set different wallpapers for your Home and Lock screens. Of course, you can opt to have the same picture on both. However, to set your Lock screen wallpaper only, follow these simple steps:
Unlock your Redmi Note 4.
Tap the “Gallery” app icon on the Home screen.
Browse the folders and open the one containing the picture you want to set as the wallpaper.
Tap the picture to open it.
Tap the “More” option.
Tap the “Set as wallpaper” option.
Crop the photo.
Select the “Set as lock screen wallpaper” option.
Another way to do it is through the “Settings” app. Here’s how that works:
Unlock the phone.
Launch the “Settings” app from the Home screen.
Tap the “Wallpaper” tab.
Tap the option “Change” beneath the “Lock Screen” picture.
Browse the available system wallpapers and tap the one you want.
Tap the “Set” button.
If you’re running MIUI 9, you can do it from the “Themes” app. The “Themes” route looks like this:
Unlock the phone.
Tap the “Themes” app icon on the Home screen.
Tap the “Wallpapers” option.
Browse the available wallpapers and tap the one you want.
Tap “Apply”.
Select the “Set as lock screen wallpaper” option.
Hide Notifications on Lock Screen
Another useful thing to know is how to hide the Lock screen notifications. You can do it through the “Settings” (on MIUI 8) app or through a third-party app (such as Floatify). Here are the steps for the “Settings” app route:
Make sure that the apps you want to hide are added to the “App lock” app.
Unlock your Redmi Note 4.
Tap the “Settings” app icon on the Home screen.
In the search bar, type “app lock”.
Tap the first result from the list, “App lock”.
Select the apps you want to add to the “Hide Notifications” list.
Next, tap the “Cog” icon in the top-right corner of the screen.
After that, tap the “Hide content” option to toggle it on.
If you opt to install Floatify, follow these steps:
Download and install the app.
Make sure to give the app the permission to access Lock screen settings.
Launch it from the Home screen.
Tap “Help”.
Tap “Lockscreen”.
Tap “Hide sensitive notification content” or “Don’t show notifications at all” options.
Set Lock Screen Timeout
Among many other options, the Redmi Note 4 allows you to customize the Lock screen timeout. If your device uses MIUI 7 or higher, here’s how to do it.
Unlock the phone.
Launch the “Settings” app.
Tap the “Lock screen & password” option.
Tap the “Sleep” button.
Pick the timeout interval.
Exit the app.
