My phone is unrooted. Is there anyway I can change all the icons in my applications tray? And is there anyway I can alphabetise all the icons in the grid view?
A good place to start is downloading
GoLauncher or someting similar (
ADW Launcher,
Launcher Pro). They are all good in their own ways, I just happen to like Go Launcher the best. You can download
themes for Go Launcher (an easy way to customize the look of your phone)...
NSutherl is correct in everything, but to expand a bit...
Rooting is not necessary just to change to look or UI of your homescreen and even beyond. The best and easiest thing to do is install a third-party launcher.
GO Launcher is not my favorite, but it is easy to apply themes, and there are a lot of them. I have been using
ADWLauncher EX for about a year now and while it is really good and versatile, it's a little buggy and likes to force close about once daily. The free
ADW.Launcher seems to be more stable. Before ADW, I used
LauncherPro which was all-around good and very stable. Never had a problem with that one and it seems to have the most logical options for customizing.
Most aftermarket launchers let you do different things with the App Drawer, like alphabetizing, categorizing, or even just hiding selected apps from the drawer entirely. If you want another way to organize apps beyond the App Drawer, try something like
Folder Organizer,
Circle Launcher, or
SiMi Folder. All of these apps allow you to organize apps into categories and even have a simple button on the homepage to bring up a menu or list of just the apps in that category.
Although Samsung usually has a pretty cool lockscreen, if you want to do other cool stuff like custom unlock sliders, custom wallpaper on the lockscreen, or even adding any widget you want to the lockscreen, you have to install
WidgetLocker - Paid App. To see what cool stuff you can do with just your lockscreen, check this out:
Post Your Lockscreen Screenshots (WidgetLocker, etc.).
Desktop Visualizer allows you to place any image at all on the desktop as a widget and use it to start an app, shortcut for a folder organizer, or even specific actions (using LauncherPro). There are tons of other apps that let you do cool things, but keep in mind that you're only changing the look (with some functionality)... so, as long as you're NOT rooted, you really can't mess anything up. So go crazy and let your imagination run wild!
Finally, I have an app on my Samsung Galaxy Tab called
Screenshot It which takes screenshots on unrooted Samsung Galaxy Tabs and phones. Be sure to post screenshots when you're done!
