Hi I am using a Sony Xperia Ion.
I just wonder if I can limit the number of home page screen to 2. Currently it has 5 screens which is way more than I need.
Thanks
Welcome to Android Central! What version of Android is it on? You can find out in Settings>About Phone>Android Version.
From what I can tell in the manual, I don't think you can modify the number of homescreens using the stock launcher. You could consider installing a 3rd party launcher like Nova, which does allow you to modify the number of homescreens, as well as other aspects of the launcher interface. Nova requires Android 4.0 and up, so if you have a version that's lower, GO Launcher might work better.
