All Android Mobile security has virus defination update option on their Android apps, why there is no option in bitdefender mobile security app?
Additionally, I had a conversation with one of the bitdefender mobile security developer and android malware researcher @agozob and according to him and bitdefender developers the cloud based scanning is more of a new technology which can detect pre existing and newly undetected android malware for which signature detections have still not been created.
