How can I tell if my phone was hacked and what should I do first?
Answer
Odd calls and fake-looking voicemails are often carrier spam or spoofing rather than a full device takeover. First update the phone, check for unknown apps, change important passwords from a safe device, and contact your carrier about call/SMS scam filtering before wiping the phone.
Before you start: stop right away if…
- Do not share one-time passcodes or remote-access control with anyone who contacts you unexpectedly.
- A factory reset erases apps and local data that are not backed up.
Follow these steps
Update the system and scan for unknown apps
Install any available OS update. In Settings, review Apps for anything you do not recognize, especially apps installed outside the official store.
You should see: The phone is updated and you have a short list of suspicious apps, if any.
Revoke risky permissions
Turn off Accessibility access, notification access, and Device admin rights for apps you do not trust. Uninstall those apps.
You should see: Suspicious apps are removed or blocked from controlling the phone.
Secure accounts from a safe device
On a trusted computer or after cleanup, change Google/Apple, email, and banking passwords and turn on two-factor authentication. Do not read codes aloud to callers.
You should see: Key accounts use new passwords and you regain normal sign-in control.
Ask the carrier about spam and line status
Contact your carrier about spam filtering and confirm the line is active. Spoofed caller ID and “not in service” messages often come from network spam, not a virus.
You should see: Spam controls are enabled or the carrier explains the call pattern.
Factory reset only if needed
If unknown apps return or the phone still misbehaves after the steps above, back up photos and perform an official factory reset, then reinstall apps only from the official store.
You should see: The phone returns to a clean setup without the previous suspicious behavior.

Extra tips
What to look for: Unknown apps you did not install, unexpected accessibility or device-admin permissions, and whether the phone still shows your carrier as in service.
Before you change anything: Write down examples of the odd calls or messages. Prefer changing passwords from a computer you trust if the phone feels compromised. Do not enter codes from unexpected callers. Back up important photos before any factory reset.
