There was a widely reported bug in September with the app falsely claiming there was a newly installed app and constantly scanning as a result. Supposedly, the issue was fixed. However, the bug is back. Doesn't inspire much confidence in the app when the same bug keeps cropping up. 2025-02-27 - the constant scanning was gone for a few weeks, but now is back. If they can't figure out how to make the app work properly on Android, what does that say about how well the app will protect your phone?

For reasons of economy, I had to abstain from getting the paid version this time around. However, the paid version was excellent. It protected me many times. Now I'm trying the free version and it's nice light, it's fast. My system resources aren't affected at all. It's a good app, I recommend it. September 2025: bit defender free.SAvedmy phone from a barrage of ADS, and I had a cheaper antivirus in place with Total AV. At renewal going back to BDef!

This is a great app with only 1 major downfall. It definitely protects your phone and security, but you will have to deal with repeated alerts over instances of files you may have because they are "untrusted" by the app. If the devs put in a whitelist to keep those files from being constantly alerted to your phone, I would give this a 5 star.
