Rule out stalkerware first
The settings to check, one by one
Paired devices in Google Messages
Open Messages → profile icon → Device pairing (or Messages for web). Any browser or device paired here receives a live copy of your texts — including bank and login codes. Unpair anything you don’t recognise.
Devices signed into your Google Account
Go to Settings → Google → Manage your Google Account → Security → Your devices. Anything signed in here can reach your email, photos, backups and location. Tap a device you don’t own and Sign out.
Who can see your location
Check Google Maps → profile icon → Location sharing and Find My Device for anyone you’re sharing with. Stop any sharing you didn’t set up or no longer want.
Notification access
Open Settings → Notifications → Device & app notifications (or search Notification access). An app with this permission can read every notification you get — message previews, codes, everything. Revoke it for anything you don’t recognise.
Call and SMS forwarding
In the Phone app → Settings → Call forwarding, check nothing is quietly sending your calls elsewhere. Watch too for any ‘SMS forwarder’ app that copies your texts onward.
Your Google account recovery details
In Google Account → Security, check the recovery phone and email. A number or address someone else added lets them reset their way back in even after you change your password. Remove anything that isn’t yours.
Found something — and you know who's behind it?
Just want it to stop?

Will a malware scan find any of this?
Is changing my Google password enough?
If I remove their access, will they know?
