After faced many android phones such as HTC, Samsung and SonyEricsson, I can see that most of them are really hard to install an app the reason is those phone doesn't have Application Installer or File manger. Now you can install any app on the device which does not have Application Installer or File manger by following this few steps:
1.Download Android PC suit from
HERE (choose 91 PC Suit for Android)
2.Install it then connect your phone to PC and open it.
3.Follow the instruction on the box of PC Suit.
4.Go to app then click on install.
5.Click on Add button on the left top, search for app that you want yo install. Done!
