Android 10 lets you personalize your device by adding a profile picture to your lock screen. Not only will your image or avatar be added to your lock screen, it will also be added to the Quick Settings menu. It's a nice touch of customization that makes your device feel like your own.
When you sign in to Gmail and other services, you'll see a small picture of you. A simple indicator that informs you that the device and the app you are using belong to you . Now there is a similar icon on the lock screen of Android 10 and in the notification bar, but by default it's a simple silhouette. However, with a few quick clicks, you can change that to any picture you like.
Setting Up Your Profile Image
Open the Settings app and tap System. Next, select "Multiple Users". Here you see yourself and a guest user. Touch your profile name ̵
After selecting Choose Image, you can use the default File Selector app to find a photo in the camera roll of your phone. Once you've selected the ideal image, you can crop it by zooming in or out and then clicking Done. You will see the previous screen with the "Profile info" popup. Press the "OK" button. Now you see your avatar in the upper right corner of your lock screen and in the lower right corner of your quick settings!
