Review summary

Users praise F-Secure for strong protection and reliability across devices, but report crashes, intrusive upgrade prompts, and compatibility issues on some tablets. False positives and cancellation/support friction further frustrate users. Overall, protection is valued, but stability and UX/purchasing friction hinder satisfaction.

Pros

Strong protection and threat removal; users report threats being detected and removed and safe browsing working.
Long-standing trust and reliability across devices; many users have used it for years and feel safe.
Quiet background operation with minimal interruptions; fewer pop-ups compared to competitors.
Broad device compatibility and consistent protection across phones and tablets.

Cons

Frequent crashes/force closes, especially on tablets and newer Android versions.
Intrusive upgrade prompts and confusing premium sign-up overlay; perceived pressure to pay.
Tablet-specific compatibility bugs on certain devices (e.g., Samsung tablets, Android 16).
False positives that block legitimate content or services (e.g., legitimate sites or app links).
Cancellation and support friction; difficulty canceling and slow or unhelpful responses.

2026-08-14	Di*****	Nice app, simple UI. However I've faced several issues which are probably device specific. So, first issue is happened during SIM-swap (actually it was remote switch to H+ on eSim where APN bearers are set for LTE, NR only): an email contained: "We were unable to take a photo when this happened", strange. Web Filtering was deactivated in app after that. Second: counter of safe apps is looks like 0/15 where 15 is amount of newly installed or updated apps but not those I had already installed.

2026-08-14	Ge*****	F-Secure flags a supposed Trojan that other malware apps do not find, recommends deleting it, and then fails to delete it, providing no further action or recommendations.
