Disadvantages Need internet connection - Android requires an active internet

connection. At least there should be a GPRS internet connection in

your area, so that the device is ready to go online according to our

needs.

Advertising - Application in the Android phones can indeed beobtained easily and for free, but the consequences in each of these

applications, will always be ads on display, either the top or bottom ofthe application.

Wasteful Battery - Android more wasteful than any other operatingsystem, because this operating system is a lot of "process in

the background that lead to the battery quickly drains.

Many applications contain virus - the virus inserted androidapplications including Counter Strike Ground Force, Puzzle Photo Ga

me, etc. Android Application contain virus also present in the Android

Market.


34/45

Its open security free business model lacking

security keys and code-signing certificates allows

any application to install and run, which is perhapsthe biggest drawback.

The magnitude of possible malware and junkware

allows the phone to be used as a tool for

advertisers. The Android platform cannot be installed on or run

from a SD card.

The Java enabled system cannot be installed on

the memory card. Thus apps and software have to be downloaded

direct onto the phones own memory, which

obviously takes up much-needed space.
