Push notifications not working on So App?

A bunch of users might only receive push notifications if the app is open but not when it is closed, which defeats the purpose of push notifications.

This happens only on phones by manufacturers like Xiaomi, Oppo, One Plus, Vivo, Lenovo, Huawei, Samsung, and a few others.

Why is this happening?

On certain stock ROMs (Android operating system customized by device manufacturers), clearing an application kills that application and its background services. This is bad because we need background services to show Push Notifications.

Why don’t apps like Gmail and Whatsapp have these problems?

Top-popular apps like Gmail, Slack and Whatsapp are whitelisted by these stock ROMs. That means these apps have auto-launch enabled for them by default. Users explicitly need to enable auto launch for other applications.

I can’t find the settings to enable auto-launch. Where are they located?

The steps to enable auto-launch for an app are different for different manufacturers. This is because this is not a native Android feature and is very specific to stock ROMs.

NOTE: It should also be noted that the terminology used by each manufacturer is different. The auto-launch feature can be referred to as app auto-start, start-up manager, auto-start manager, app optimisation, protected apps, or background app management.
