This app requires Device Administrator permission to enable Anti-Theft features.
The Accessibility service is required to:
• Scan links in supported browsers for web protection
• Scan chat messages to detect scams
• Monitor app behaviour to identify advanced threats

Solely for the purpose of enabling these features, Bitdefender Mobile Security may collect and process URLs accessed via browsers or chat messages, as well as certain app activity events. **Collected data is never shared with third parties.**

Bitdefender Mobile Security & Antivirus uses foreground services (TYPE_SPECIAL_USE) to detect **PACKAGE_INSTALLED** events as quickly as possible and scan installed or updated apps before they are opened — a core feature of the app.

I have had a perfect experience with this app for almost a little more than 10 years. From around 3 months ago, unfortunately, web browsing protection, app anomaly detection and scam alert keep getting turned off at random moments. I think, this happened after Google Play updates which involved quite a few core Google app updates. Battery optimisation is switched off and background activity is permitted for the app as before! I may finally have to leave this app soon, if this continues.

Shifting after many years with another provider, and so far, excellent result with Windows on laptop version. Like the promised fast speed and small footprint on general use, so thought I'd try the mobile version. Trying the initial free trial as there was an email glitch with a previous install, and this time, much better.

You kinda have to trust it works. Three stars because it seems to be behind the times a little. Messages that are legitimate are blocked while actual spam and phishing comes through. And, there's no reporting to submit these false positives. A few times the app turned off security features that I had turned on. That happened following a few updates. Overall, I trust BitDefender and keep subscribing to it for peace of mind. hope to see more mobile features.
