Over the years, Android and iOS have borrowed features and UI elements from one another, to the point where you’ll find basically the same functionality on either platform. There are certain design differences that have stuck around, though, and the way Android treats its status bar is one of them. You’ll often find the status bars on most Android phones quite populated with all sorts of icons. Besides your usual Wi-Fi, Bluetooth, and mobile data indicators, most OEMs have their own set of icons to represent different features. If your Samsung phone is displaying a triangle symbol, it could point to the Data saver feature being enabled.
You can confirm this if you can spot two arrows inside the triangle pointing in opposite directions (up and down) when looking closely at the icon. As its name suggests, Data saver helps you reduce mobile data usage. It does so by restricting background data consumption by apps. Your Android phone does a lot even when you’re not actively using an app. Third-party apps and games often pull data in the background to refresh content, sync information, check for notifications, and download media.
You can configure the allowlist to let certain apps continue using mobile data in the background by navigating to Settings > Connections > Data usage > Data saver > Allowed to use data while Data saver is on. Of course, if you’re connected to Wi-Fi most of the time, you can turn the feature off.
It could also be a warning notification
You can turn off Data saver on your Samsung phone if you don’t require the feature. However, if the triangle icon still doesn’t disappear, it might not be related to the Data saver feature at all. Android typically uses a triangle symbol with an exclamation mark to indicate a warning or an issue that warrants your attention. Samsung does this too and says that your phone “requires your attention due to a warning, issue, or action that may need to be completed.”
The exact cause of this warning can vary, though. It could be related to a failed software update, an issue with your SIM card, or insufficient storage on your device. To view more information about the warning, you’ll need to pull down the notification panel and tap on the warning to see what action it wants you to take. Many common issues with Android can often be fixed by troubleshooting your network, restarting your phone, or making some space by deleting unwanted apps and files.
If you spot a yellow triangle icon when trying to charge your phone, it could be an indication of a faulty charging adapter or USB cable. Try swapping the adapter or cable for ones that you know work so you can rule out the possibility of a broken accessory. If using a different charger doesn’t solve the issue, it could be worth contacting Samsung support to get your phone’s USB-C port assessed.
Check if it’s a notification from a third-party app
What differentiates Android from iOS is that third-party apps can also display their notifications in the form of status bar icons. This can be immensely useful, since you don’t need to always swipe down to check whether you have any pending notifications. However, this does mean that an app installed on your phone could have a triangular notification icon that’s throwing you off.
The quickest way to identify which app the icon belongs to is to pull down the notification panel and look for a notification with the same symbol. It could be an app that has a triangle logo, for all you know. In case the icon bothers you and you deem the notification to not be particularly important, you can turn notifications off for the app itself. On your Samsung phone, navigate to Settings > Notifications > App notifications. Here, select the app and tap the “Show notifications” option to disable alerts.
Android actually gives you granular control over which types of notifications an app is allowed to send. This lets you disable, say, an app’s promotional notifications while keeping its more important alerts, like messages or delivery updates, enabled. You’ll first have to enable this feature on your Samsung phone by heading to Settings > Notifications > Advanced settings and turning the “Manage notification categories for each app” option on. This will now let you individually configure notification channels for each app.
Other symbols to look out for
The triangle warning symbol is not the only status bar icon that might be unfamiliar to new Samsung or Android users. While most status bar icons don’t warrant immediate attention, knowing what the common ones represent might help you better understand what your phone is doing in the background. For instance, a tiny upside-down teardrop-shaped icon points to an app currently accessing your phone’s location.
A key icon on your phone’s status bar means your device is currently connected to a VPN. If you don’t recall deliberately turning on a VPN, it’s worth checking if a third-party app has established a connection without you realizing it. You can view and turn off VPN connections on your Samsung phone by navigating to Settings > Connections > More connection settings > VPN.
Another status bar icon worth recognizing is the Do Not Disturb symbol, which is represented by a circle with a horizontal line running through the middle. It silences incoming notifications and calls, which can come in handy when you’re in meetings, driving, or simply want a quick detox. Having the Do Not Disturb toggle on accidentally, though, can make you miss important messages and calls. You can create an allowlist by heading to Settings > Notifications > Do Not Disturb, then selecting contacts and apps you want to continue receiving notifications from under the “Allowed during Do Not Disturb” section.
