As a user of Samsung Galaxy S4, we often find problem when downloading something using wi-fi connection, because the connection will be disconnected when the samsung galaxy S4’s screen turns off.
So, how to make the connection still connected when the screen turns off? Try to follow these steps below
Fixing Wi-Fi disconnected when Galaxy S4 screen turns off
- Directly go to Settings, tap Connections.

- There you’ll find an option says “Keep Wi–Fi on during sleep,” Select“Always.”
