• Android is a multi-process system, in which each application runs in its own
process.
• Most security between applications and the system is enforced at the process
level through standard Linux facilities, such as user and group IDs that are
assigned to applications.
• Android is designed having multi layer security which provides flexibility for this
platform,

malware.
• Sometimes slow device company issued an official version of Android
your own.
• Very unstable and often hang or crash.
• Usually you need more code on Java than Objective-C.
• Low security and fake apps can be installed to steal your info from
unknown resources
16. Conclusion
• I’ve learned through my research that Android is a much more diverse
operating system than iOS and Windows Mobile Phone.
• Android has grown rapidly over the past 6 years becoming the most used
smartphone operating system in the world.
• It’s because Android doesn’t release 1 phone from 1 company with 1 new
OS every year, but countless phones from numerous companies, adding
their own twist, throughout the year, developing gradually day-by-day.
• I am not one to say that Android is better or worse than one OS, but it is
unique and incomparable to other mobile operating systems.
