Truecaller Keeps Crashing? 7 Step-by-Step Solutions (2026)
The most common cause of Truecaller crashing is a corrupted cache — especially after an update that did not complete cleanly. Clear the cache first (Settings → Apps → Truecaller → Storage → Clear Cache); if it still crashes, clear all app data. These two steps fix roughly 80% of crash issues.
Truecaller crashing is one of the most-reported issues on Android forums — particularly after app updates, Android OS upgrades, or when the device runs low on storage. The crash can manifest as the app force-closing on launch, freezing mid-use, or crashing specifically when an incoming call arrives. Each pattern points to a different root cause.
Identify Your Crash Pattern First
| When does it crash? | Most likely cause | Go to fix |
|---|---|---|
| On launch / opening the app | Corrupted cache or app data | Fix 1, Fix 2 |
| During an incoming call | Memory conflict with Phone app | Fix 3, Fix 4 |
| After a recent app update | Incomplete update, corrupted install | Fix 2, Fix 6 |
| After Android OS update | Version incompatibility | Fix 5, Fix 6 |
| Randomly / no pattern | Low storage or RAM pressure | Fix 4, Fix 7 |
Fix 1 — Clear Truecaller Cache
Cache corruption is the single most common crash cause — and the easiest to fix. Clearing cache removes all temporary files without deleting your account, settings, or history. It’s risk-free and takes 10 seconds.
- Settings → Apps → Truecaller → Storage. On some Samsung devices this may be under Apps → Truecaller → Storage usage.
- Tap “Clear Cache”. This removes only temporary files. Your account stays logged in, and all your settings and history are preserved.
Settings → Apps → Truecaller → Storage → Clear Cache - Reopen Truecaller. If it opens without crashing, you’re done. If it still crashes, proceed to Fix 2.
Fix 2 — Clear All App Data
If clearing cache doesn’t stop the crash, the app’s internal database or settings file is likely corrupted. Clearing all data performs a deeper reset — equivalent to a fresh install without uninstalling the app. You will need to log in again.
- Settings → Apps → Truecaller → Storage → Clear Data. Confirm the warning. This wipes your local Truecaller data — your account exists on Truecaller’s servers and will restore when you log in again.
Settings → Apps → Truecaller → Storage → Clear Data - Log back in and re-verify your number. Enter your phone number, receive the OTP, and verify. Your account, contacts, and Premium subscription will sync automatically.
Fix 3 — Force Stop and Restart the Service
Sometimes Truecaller’s background service gets stuck in a bad state — particularly after a phone comes out of deep sleep or a call is dropped mid-identification. Force stopping the app clears the stuck state.
- Settings → Apps → Truecaller → Force Stop. Tap Force Stop → confirm.
Settings → Apps → Truecaller → Force Stop - Wait 10 seconds, then reopen Truecaller. Opening the app after Force Stop creates a completely fresh process — no inherited state from the stuck service.
Fix 4 — Free Up Device Storage
Truecaller’s local spam database and caller ID cache can grow large over time. If your device has less than 1GB of free storage, Android may kill Truecaller processes mid-operation to reclaim memory — which looks like a crash from the user’s perspective.
- Check storage: Settings → Storage → see available space
- Aim for at least 2GB free for stable app performance
- Delete unused apps, clear other app caches, or move photos to cloud storage
- After freeing space, clear Truecaller’s cache again (Fix 1) to let it rebuild cleanly
Fix 5 — Update Truecaller to v27
Several crash bugs affecting Android 14 and 15 devices were patched in Truecaller v27. If you’re on v24 or older, these crashes may be known fixed issues. Update via the Google Play Store (Truecaller on Google Play).
Tip: After updating, do not skip the restart. Some crash fixes in v27 require a device reboot to take effect — particularly the fixes for call-time crashes on Samsung devices running One UI 7.
Fix 6 — Uninstall and Reinstall Cleanly
If the app still crashes after clearing data and updating, the app installation itself may be corrupted — a rare but real issue that occurs when downloads are interrupted or storage fails mid-write. A full uninstall and fresh install from the Play Store resolves this.
- Long-press Truecaller → Uninstall → confirm. Alternatively: Settings → Apps → Truecaller → Uninstall.
- Restart your device. A reboot clears all cached process data from the uninstalled app.
- Reinstall from the Play Store. Open Google Play → search Truecaller → Install.
- Re-grant all permissions and re-apply settings. Grant Phone, Contacts, Call Logs, Notifications, and Display over other apps. Re-set as the default caller ID app. Set battery to Unrestricted.
Fix 7 — Check for Conflicts With Other Caller ID Apps
Running Truecaller alongside another caller ID app (CallApp, Hiya, GetContact) creates conflicts — both apps try to intercept the same incoming call event, causing one or both to crash. You should only have one active caller ID app at a time.
- Open Settings → Apps and look for any other caller ID, phone, or spam-blocking apps
- If found: either uninstall the competing app, or disable its “Caller ID” and “Default phone app” permissions
- Common conflicting apps: CallApp, GetContact, Hiya, Google Phone’s built-in spam protection (disable in Google Phone settings → Spam protection → off)

Frequently Asked Questions
Why does Truecaller crash every time an incoming call arrives?
Call-time crashes are most commonly caused by a conflict with another caller ID app, insufficient device RAM, or a corrupted install. Start by checking for competing caller ID apps (Fix 7), then try a clean reinstall (Fix 6). On Samsung devices, also check if Samsung’s built-in spam protection is enabled and conflicting.
Does clearing data delete my Truecaller account?
No. Clearing app data only removes local files on your device. Your Truecaller account, Premium subscription, block list, and contact history are stored on Truecaller’s servers. They restore automatically when you log back in after clearing data.
Truecaller crashes only on Samsung — is this a known issue?
Yes. Samsung’s One UI 7 introduced additional memory management changes that conflict with Truecaller’s call-time overlay. The fixes are: update to v27, add Truecaller to Never Sleeping Apps (Settings → Battery → Background usage limits), and ensure Samsung’s own spam protection is disabled in the Phone app settings.
