How to distinguish ordinary mobile or browser failures from signs of unwanted software, unsafe configuration, or account compromise.
Mobile and browser issues may be isolated application faults, connectivity problems, or security symptoms. Establish the scope before clearing data, resetting a device, or replacing hardware.
| Symptom | First checks |
|---|---|
| One mobile app fails | App update, storage, permissions, account state, and platform compatibility |
| Unexpected ads, warnings, or network use | Unwanted application, browser extension, notification permission, or account compromise |
| Browser redirects or changed search behavior | Extensions, browser settings, download history, and security scan |
| Wi-Fi, Bluetooth, or NFC problem | Radio state, pairing, settings, and device support |
| Autorotation issue | Rotation lock, app behavior, sensor state, and operating-system condition |
Avoid installing software from untrusted sources or bypassing platform protections. Treat unexpected requests for credentials or security codes as a separate identity-security issue.
