How to Set Up Getcaller on OnePlus Devices (OxygenOS)
OnePlus phones run OxygenOS, which includes its own battery-management and app-permission system. Like other Android manufacturers, OxygenOS can limit which apps run in the background by default — and if Getcaller's caller ID or notifications feel inconsistent, a few settings changes usually help.
Why extra setup helps
OxygenOS is designed to save battery by restricting background activity and automatic app launches unless you allow an app to run freely. This is useful for battery life, but it can also stop apps like Getcaller from checking for calls or delivering notifications the way you expect. The steps below tell your phone to treat Getcaller as an exception.
Setting Up Getcaller on OnePlus
Step 1: Allow unrestricted battery usage
Open Settings > Battery > Battery Optimization (or Settings > Battery > App Battery Management on newer OxygenOS versions), find Getcaller, and choose "Don't optimize" or "Allow background activity." Menu names vary slightly by OxygenOS version.
Step 2: Enable autostart
Go to Settings > Apps > App management (or open the Phone Manager app if your device has one), find Getcaller, and turn Autostart or Auto-launch On so it can check for calls even when it isn't open.
Step 3: Lock Getcaller in recent apps
Open Getcaller, then open your recent apps view. Find the Getcaller card and tap the lock icon (or swipe down on the card) if available, so the system doesn't close it when you clear recent apps.
Check notification permissions
Also confirm Settings > Notifications > App notifications has Getcaller allowed — some OnePlus models manage notification access separately from battery and autostart settings.
Other Android brands
The same idea — protecting the app from automatic battery cleanup and allowing background activity — applies to other Android manufacturers with similar systems, including Xiaomi (MIUI), Samsung (One UI), Huawei/Honor (EMUI/HarmonyOS), and Oppo/Vivo (ColorOS/Funtouch). See our Xiaomi and MIUI setup guide, Samsung setup guide, Huawei and Honor setup guide, or Oppo and Vivo setup guide for device-specific steps.
Confirm it's working
After making these changes, use Getcaller normally for a day. If caller ID or notifications still feel inconsistent, double-check each setting above — OxygenOS updates occasionally reset autostart and battery permissions.
Summary
OnePlus phones use OxygenOS battery tools that can limit background apps by default. Allowing unrestricted battery usage, enabling autostart, and locking Getcaller in recent apps covers the setup most OnePlus devices need.
