My ex told me that she had a tech-savvy friend hack my WhatsApp. She insists it was not just a linked device. She apparently read messages in real time—once, after I exchanged messages with someone, she called within minutes asking why that person had contacted me. She had full access to my phone during our relationship, and her only clue was that my phone had "options you don't know about." She says she deleted everything now that we have broken up, but I don't know whether to trust that. How can I determine what happened, preserve evidence if necessary, and secure my phone and accounts going forward?

Some legitimate features, such as phone-to-PC integrations, notification access, screen sharing, or accessibility tools, can expose messages without a sophisticated “hack.” That still requires access or permission, so review those settings carefully. If someone can still access your accounts after a reset and password changes, secure the accounts first and consider professional help rather than repeatedly deleting random apps.
The safest cleanup is usually to back up only personal files such as photos and documents to a computer, then factory-reset the phone and set it up as new. Do not restore apps or a complete device backup, because that could bring the unwanted software back. If you suspect a deeper compromise, have Samsung support or a reputable mobile-security professional reflash the official system software, or use a replacement phone.
Since she had unsupervised access to the phone, stalkerware or an app with excessive permissions is plausible. Check Settings for Device admin apps, Accessibility services, Notification access, VPNs, apps allowed to appear on top, usage-data access, all-files access, and apps allowed to install unknown software. Also review the complete app list for unfamiliar or duplicate apps. These checks may provide clues, but they cannot prove the phone is clean.
If you may want to report this, preserve evidence before wiping the phone: save her messages and write down dates and details of what happened. A factory reset can remove useful evidence, and authorities may want to examine or copy the device. Avoid confronting her further from accounts that might still be compromised.
Change your Google, Samsung, email, banking, and messaging passwords from a trusted device, enable two-factor authentication, and sign out unfamiliar sessions. Review WhatsApp’s linked devices as well. Change the phone’s PIN and make sure your recovery email and phone number belong only to you. A reputable mobile security scanner can help identify common stalkerware, but a clean reset is more reliable than trying to identify every hidden app.
