If you are a Gmail user on Android mobile, then you may want to change your profile picture. This is because on some devices, the default profile picture is not very attractive. To change your profile picture on Android mobile, first open the Google Play Store and search for “Gmail Profile Picture.” Once you find the app, open it and select the “Change Profile Picture” option. Once you select this option, you will be able to choose a new profile picture for your account. You can either choose a photo that is representative of who you are or choose one that is more stylish. If you have a phone with an HD display, then your profile picture will look great on this type of device. However, if your phone has a lower-resolution display, then your profile picture may not look as good as it should. So be sure to test out different profiles pictures before choosing one that is best for you!
