Call and Text From Your Realme Phone With Your Computer (realme UI Setup)

Call and Text From Your Realme Phone With Your Computer

Your Realme can put its calls and texts in any computer browser with ComputerCaller — your own SIM and number, phone face-down on the shelf. The setup is 3 minutes. The catch you should know before starting: realme UI is built on OPPO's ColorOS, and that family runs one of Android's most aggressive background-app killers — it kills apps even after the standard Android battery exemption is granted. We test on this software family ourselves, so the two settings in step 4 aren't copied from a forum: they're the ones that actually keep the companion app alive.

Compatibility check

• Any Realme with Google Play and Android 8+ — GT series, numbered series, C-series, Narzo (realme UI 1.0 and up).
• The SIM must be in the Realme — calls and texts go out on your real number.
• On C-series and other budget Realmes with 3–4 GB RAM, the killer strikes faster (less memory headroom), so step 4 matters even more.

Step 1: Install the companion app

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

Step 2: Permissions, in the app's order

1. Notifications — first; your connection indicator.
2. Phone and SMS — the core: calls and texts on your number.
3. Contacts — names, not raw numbers, in the browser.
4. Battery exemption — last. Accept it, then treat it as step one of two — on realme UI it doesn't stop the vendor killer by itself. The app shows a hint on Realme devices pointing to the settings below, for exactly that reason.

Step 3: Pair at computercaller.com

1. On the computer, open computercaller.com — any browser, any OS.
2. Sign in with the same Google account, follow the pairing prompt.
3. App shows connected → you're texting and calling from the browser.

Step 4: The two realme UI settings that keep sync alive

1. Allow background activity:

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

2. Auto-launch:

• Same app page → enable Auto-launch (some realme UI versions keep a master list at Settings → Apps → Auto-launch)
• This is the permission to come back from the dead. realme UI will kill the app's process eventually; auto-launch is what lets it restart and reconnect without you.

Sync stopped? The Realme checklist

• Step 4 settings after updates: realme UI updates can reset battery choices — always the first re-check.
• Quick freeze / sleep standby optimization: Settings → Battery → More settings — realme UI's deep-sleep features freeze background apps overnight. If your sync is dead every morning, this is the likely cause; disable sleep standby optimization or whitelist the app where offered.
• Power saving modes: suspend background apps wholesale; reopen the companion app afterwards.
• "Clear all" in recents: can kill even exempted apps on this family. Leave the app's card be, or lock it (long-press → Lock).
• Phone Manager cleanup: add DNK Dialer Companion to its allowed list if you run cleanups.
• Right-now fix: open the companion app — it reconnects on launch.

Menu names drift between realme UI 2, 3, 4 and 5 — if a path doesn't match your phone, search "auto-launch" or "background" in Settings and you'll land on the right screen.

Realme FAQ

Is Realme worse than OPPO or OnePlus for this? Same engine, same rules. Budget models just kill faster because they have less RAM. Guides for the siblings: OPPO, OnePlus.

Battery drain from keeping it alive? Small — the app idles. It gets killed for being quiet, not for being greedy.

Price? ComputerCaller is $5 USD/month with a 7-day free trial — a full week to confirm realme UI leaves the app alone before you pay. The companion app is a free download.
