Realme, Oppo, Vivo, OnePlus and iQOO setup

These brands belong to one maker (BBK) and run on closely related skins — ColorOS, OriginOS and OxygenOS. All of them block third-party auto-start by default and enable strict sleep optimization, which is why call notifications disappear and reminders fire late. The settings below are the same for all of these phones; item names may differ slightly between versions.

Step 1. Enable auto-start

Open Settings → Apps → App management → ProZvonki and turn on Allow auto-launch. This is the key item for ColorOS/OriginOS — without it the app won't run in the background.

Step 2. Allow background activity

In the app card open Battery usage (or "Power consumption") and enable Allow background activity, turning off smart/intelligent optimization for this app. Also allow "High background power consumption" if the system asks.

Step 3. Disable sleep standby optimization

Open Settings → Battery → (⋮ or Battery settings) and turn off Sleep standby optimization. It periodically "freezes" background apps at night — because of it you lose overnight and early-morning notifications.

Step 4. Lock in Recents

Open the Recents menu, long-press the ProZvonki card (or swipe it down) and choose Lock. A locked card won't be closed by the memory-clear button.

Step 5. Allow exact alarms and notifications

Open Settings → Apps → Special app access → Alarms & reminders and enable ProZvonki (Android 12+). Make sure the app's notifications are on (Android 13+).

Tip: ColorOS has a separate Startup Manager inside the "Phone Manager" app — if you can't find auto-start in the app card, look for it there.

FAQ

Frequently asked questions — Realme, Oppo, Vivo

Where is auto-start on Realme/Oppo?

Settings → Apps → App management → ProZvonki → Allow auto-launch. Or in the "Phone Manager" app → Startup Manager.

Notifications stop arriving at night

That's Sleep standby optimization freezing the app (step 3). Turn it off in Battery settings and allow background activity for the app (step 2).

Does this guide apply to OnePlus and iQOO?

Yes. OnePlus (OxygenOS) and iQOO (close to OriginOS/Funtouch) belong to the same maker and have the same auto-start and background optimization settings. The items are named almost identically.
