Thanks for being with Samsung and for sharing your concern. We would like to inform you that the ultra data saving and opera max reduce your mobile data usage by preventing background apps from using the mobile data connection. You can use the data compression feature to compress Internet data, such as images, videos, and webpages, accessed via the mobile network.
