Bitdefender Mobile Security

Google protects your personal information.

I've dropped this app to 4* because the App Lock is so frustrating. On all my phones you are asked for your fingerprint. It works but then presents you with the number pad and you have to take 'use fingerprint' and do it again. When an app relocks is totally random. However, apart from that it is comprehensive and the paid version has a fast reliable unlimited VPN. It doesn't nag you or crave your attention as other security apps do. Gets universally good reviews from independent testers.
