2
3The tables below show whether an app has network access while on background depending on the status of Data Saver mode, Battery Saver mode, and the app's allowlist on those restricted modes.

5### How to read the tables

7The 2 topmost rows define the Battery Saver mode and whether the app is allowlisted or not for it.
8The 2  leftmost columns define the Data Saver mode and whether the app is allowlisted, not allowlisted, or denylisted for it.
9The cells define the network status when the app is on background.

14* **DS OFF**: Data Saver Mode is off
15* **BS ON**: Battery Saver Mode is on
16* **BS OFF**: Battery Saver Mode is off
17* **AL**: app is allowlisted
18* **!AL**: app is not allowlisted
19* **DL**: app is denylisted
20* **ok**: network access granted while app on background (NetworkInfo's state/detailed state should be `CONNECTED` / `CONNECTED`)
21* **blk**: network access blocked while app on background (NetworkInfo's state/detailed state should be `DISCONNECTED` / `BLOCKED`)
