Samsung triangle icon usually indicates Data Saver is enabled
The broken triangle icon on a Samsung Galaxy phone usually indicates that Data Saver is enabled, rather than signalling a fault or security issue. The feature helps conserve mobile data by restricting internet access for apps running in the background, and may also improve battery life by reducing background activity.
Data Saver is found under Settings > Connections > Data usage, although wording and icons can vary by model, carrier and software version. It is most useful when a monthly data allowance is running low or when travelling and facing roaming charges, but it can interrupt background tasks such as uploads and notifications; selected apps can be given permission to continue operating.
