Call and Text From Your OnePlus Phone With Your Computer (OxygenOS Setup)

Call and Text From Your OnePlus Phone With Your Computer

ComputerCaller puts your OnePlus phone's calls and texts in any computer browser — real number, real SIM, phone untouched in your pocket. Setup: 3 minutes. One thing OnePlus veterans already suspect: since OxygenOS merged with OPPO's ColorOS codebase (OxygenOS 12 and later), OnePlus phones inherited ColorOS's aggressive background-app killer. The standard Android battery exemption is not enough on a modern OnePlus — you need "Allow background activity" and auto-launch too. Exact paths below; we test on this software family ourselves, so these are the settings that actually work, not guesses.

Will it work on my OnePlus?

• Any OnePlus with Google Play and Android 8+ — numbered flagships, R-series, Nord.
• OxygenOS 11 or older (OnePlus 8 era and earlier): closer to stock Android, gentler killer — you may only need the standard exemption. OxygenOS 12+: assume ColorOS rules and do all of step 4.
• The SIM must be in the OnePlus — calls and texts go out on your number.

Step 1: Install the companion app

1. From Google Play, install DNK Dialer Companion.
2. Open it and sign in with Google — the same account you'll use on the computer.

Step 2: Permissions, in the order the app asks

1. Notifications — first, so you can see connection status.
2. Phone and SMS — the app's whole job.
3. Contacts — names in the browser.
4. Battery (ignore optimizations) — last. Accept it. On OxygenOS 12+ the app follows up with a hint pointing at the extra settings in step 4 — that hint exists because on this software the standard exemption alone doesn't hold.

Step 3: Pair at computercaller.com

1. Open computercaller.com on the computer — any browser, any OS.
2. Sign in with the same Google account, follow the pairing prompt.
3. Connected → your OnePlus calls and texts are live in the tab.

Step 4: OxygenOS keep-alive settings

1. Allow background activity:

• Settings → Apps → App management → DNK Dialer Companion → Battery usage
• Enable Allow background activity (enable "Allow foreground activity"/"Don't optimize" too where your version shows them)

2. Auto-launch:

• Same app page → enable Auto-launch
• This is what lets the app restart itself after OxygenOS kills the process. Skip it and the first kill ends your sync until you manually reopen the app.

3. (Older OxygenOS 11 and earlier) Settings → Battery → Battery optimization → DNK Dialer Companion → Don't optimize — usually sufficient on its own there.

Sync stopped? The OnePlus checklist

• Both step 4 toggles still on? System updates have reset battery choices before — re-check after every OTA.
• Battery saver: OnePlus power-saving modes suspend background apps regardless. Reopen the companion app after heavy battery-saver use.
• "Clear all" in recents: on OxygenOS 12+ this can kill exempted apps too. Leave the companion app's card alone, or lock it (long-press the card → Lock).
• Deep optimization / Phone Manager cleanups: add the app to any allowed/protected list your version offers.
• Fastest fix: open the companion app once — it reconnects on launch.

Menus differ between OxygenOS 12, 13, 14 and regions; if a path doesn't match, search "auto-launch" or "battery usage" in Settings.

OnePlus FAQ

My old OnePlus never killed apps — why does my new one? The OxygenOS/ColorOS merger. Your memory is correct; the software changed underneath you.

Battery impact? Minimal — the companion app idles in the background.

Price? ComputerCaller is $5 USD/month with a 7-day free trial — long enough to verify the OxygenOS settings hold before you pay. The app download is free.

Have an OPPO or Realme in the family? Same software base, slightly different menus: OPPO guide, Realme guide.
