The broken triangle explained

Samsung Galaxy phones show a broken triangle with two arrows pointing up and down when Data Saver is active. This feature protects your data allowance from being used up.

Other triangle symbols mean different things

A solid dark triangle with an exclamation mark warns of a charging fault or software glitch. A plain triangle means cellular roaming is active. Icons can vary by phone model and carrier.

How Data Saver works

When Data Saver is on, only your active app can access the internet. Background apps cannot download updates, sync data, fetch content, or receive alerts and notifications.

“apps cannot access the internet in the background, only your currently active app can do so”

Data Saver is off by default

Most Galaxy users never encounter Data Saver because it is usually off by default. You can toggle it on or off in Settings, Connections, Data usage.

You can exempt specific apps

While Data Saver is on, you can give certain apps permission to work normally in the background. Go to Settings, Connections, Data usage, then tap Allowed to use data while Data Saver is on.

When to use Data Saver

If you spend most time on Wi-Fi, you probably won't need Data Saver. Turn it on when traveling to manage expensive roaming charges or when your monthly bandwidth runs low.
