Auto Message After CallOPPO background apps settings for Auto Message After Call
OPPO background apps are limited by ColorOS to save battery. Two switches let Auto Message After Call keep running and send a WhatsApp after every call.
OPPO background apps need Allow background activity and auto launch turned on in ColorOS, or the phone may stop Auto Message After Call between calls.
ColorOS, the software on OPPO phones, manages battery firmly, and an app that is not exempted can be stopped soon after you leave it. Two settings decide whether Auto Message After Call survives. The first is Allow background activity, found in the app's battery settings, which OPPO describes as letting an app keep working when it is not on screen. The second is auto launch, which lets the app start by itself after the phone restarts; OPPO lists it under the Apps settings as Auto launch. With both turned on, the app is awake when a phone call ends and can open WhatsApp with your template. ColorOS also offers to lock apps in the recent apps view, which stops a clean-up from closing them. Menu names have changed across ColorOS versions, so if a label does not match, search Settings for background or auto launch.
OPPO background apps steps
- Open Settings, tap Apps, App management, choose Auto Message After Call, tap Battery usage and allow background activity.
- In Settings, Apps, Auto launch, switch the app on.
- Lock the app in recent apps if your phone offers it.
- Restart the phone and test with a call without opening the app.
OPPO explains these controls in its official community; paths differ slightly between ColorOS versions.
