dayThe Device Analyzer's data shows that the device's users open an average of 0.4-0.5 potential vulnerabilities per day. The average number of times a week has received (a vulnerability) attack. We cannot assume that the version of the app is newer than the one we have analyzed, so when our sample data is no longer the latest version, the corresponding graph also shows a sharp drop. If we re-performed our analysis of the latest APK version, we would probably see it still at 0.4 points. DA's da
