Congratulations to you on updating your device’s software version! After updating the Galaxy S8 and/or S8+ to Android Oreo, you may encounter a few new status icons in Android Oreo update for the Galaxy S8 and S8+ Smartphones. The icon you’re referring to is the new data saver status icon. The triangle icon you’ve referenced with the two arrows (up and down) inside indicates you’ve turned on the data saver option in your Samsung Galaxy device. The data saver will reduce your mobile device’s data usage. You can enable or disable data saver for the Galaxy S8 and S8+ through Settings>Connections>Data Usage>Data Saver.
