3★So, the way I see it, Bitdefender's mobile AV is pretty decent, I think, at what they do, and it isn't as overly heavy on system resources as their Windows version(s). However, Mobile Security for Android is supposed to be part of the Windows Total Security package, yet Bitdefender allows about half of the time (or maybe a little less) for trial than it does for its Total Security package. So, well I'm still evaluating the windows version, I'll be switching to ESET for my mobile security.

4★I really like it so far. I wish that it would prevent random bloatware apps that get auto installed on my phone sometimes instead of only notifying me that it is scanning them when it happens. I also hate the notification that pops up all the time that says bitdefender is running. I only want to be notified when something significant happens.

2★Unfortunately, since the last update, the app keeps crashing. It has worsened over the last week, now constantly. I've checked all the settings, cleared the cache, etc., and I still keep getting notified that the app keeps stopping. I'm wondering if this is a known issue, and if so, how to correct it. Hopefully, it's an easy fix, as Bitdefender's troubleshooting process is, sad to say, very daunting and tough to get through if I'm remembering correctly. 😔 Bitdefender, is this a known issue? ETA

1★There's only one thing that this app does that Play Protect doesn't do; App Anomaly Detection. It is really the only thing worth paying for. But it turns off... all the time. Several emails with devs on multiple occasions say they don't care. The *least* you could do is drop a notification to indicate it's not turned on so I am aware and manually start again. but no. don't care. therefore I have cancelled subscription and will not pay again.

3★It's good, but not perfect. I'm running a S21 Ultra and no matter what I do, the web protection keeps getting disabled by Samsungs optimisation system. I've excluded it from power save, data limits, etc. No luck. Not the end of the world, I just enabled web protection again. Still poses a security issue and it happens every other day give or take. But when it does work it's great. It's incredibly lightweight in terms of resources and ease of use and accuracy when hunting for malware is amazing.
