Nintendo has updated the official Switch Online app to version 1.1.0 on iOS and Android.
The update adds a much-requested feature: the ability to use the voice chat feature while using other applications, and it also works while the phone is in sleep mode.
Meaning your phone doesn’t have to be turned fully on and drain battery the entire time you’re playing Splatoon 2, and you can now check your text messages or emails without dropping out of the voice chat session.
The Switch Online App is the only way to use voice chat in games (so far only Splatoon 2 is supported). It’s a cumbersome setup that requires the player to hook up the phone to the console and headset via an accessory.
