CompTIA Exam 220-1102 Topic 3 Question 41 Discussion

Random restarting of an Android phone and the presence of applications not from the standard marketplace strongly suggest the possibility of malware.

Option A: The OS update failed While an OS update failure can cause issues, it is less likely to result in random restarts compared to malware.

Option B: The user downloaded malware Malware is a common cause of erratic behavior, including random restarts, especially when applications are installed from unofficial sources.

Option C: The device is in developer mode Developer mode alone does not typically cause random restarts. It may make the device more susceptible to issues if improper apps are installed.

Option D: The over-the-air carrier update failed Similar to the OS update, this would more likely cause consistent issues rather than random restarts.
