One of the key features of Samsung’s TouchWiz software for Android 3.0 and later is the inclusion of Mini Apps. These are simple apps that pop up in small windows on top of whatever app you’re viewing. They include a calculator, calendar, and music control widget.
You can view the Mini Apps by hitting a little arrow key in the center of the taskbar. But if you don’t actually use the Mini Apps, they’re just taking up system resources on your tablet and you run the risk of accidentally opening the Mini App tray when you swipe the bottom of your screen.
Xda-developers forum member miketoasty discovered it’s fairly easy to remove all of the Mini Apps from a Samsung Galaxy Tab 2 (7.0). The steps will probably work on other Samsung tablets running Android 4.0 with TouchWiz as well.
If your tablet is already rooted, all you need to do is open a file manager with root privileges such as Root Explorer or ES File Explorer, navigate to the System/app directory, and delete every app with the word “mini” in it. Then delete the System/framework/minimode.jar file and reboot your tablet.
Once Android loads, you should have a Galaxy Tab with TouchWiz… but without Mini Apps or the Mini App tray.
In case it wasn’t obvious, this will permanently delete the apps, so if you think you might want them back one day, it might be a good idea to backup your device using ClockworkMod Recovery or TWRP before getting started.
