: In this widely spread new era, Smartphone modern Operating systems are Android & ios are one which use of Mobile platforms more increasing rapidly. In all over the world, we just discussed and focused on their part of loaded inherent security and privacy by Comparative study under application development with their individual Features, secure and Threats level models of OS to protect from vulnerability under by detecting malware attacks. In this paper, we signify and focused instead of interacting to how android and ios Smartphone Operating System are taken protection over the world, under criminals malware detection of malicious applications attack, results of their study showed high percentage of such attack in the Smartphone’s device those are built on Operating System with many vulnerabilities are revealed? but we discussed on the behalf part of device manufacturer phase (write device driver) come face to new advance security challenges you need to address with integrated design/architecture and the problem faced with the ugly truth behind android upgrade problem under device-level, the security model describe user data with secure keychain services, apps spitting technique, reverse engineering etc. utmost Device (mobile phone) manufacture make their money by selling phones only right? And surprisingly, selling phones remains their primary focus instead make compatibility related to an Android platform of advance device-level security for any kind of operating system security.
