Do you want to quickly see how much memory/internal storage you have? Here’s a nice utility : NotiSysinfo
This app is really simple and nice. After installing it you have to enable the service. You can do it by changing to ON the NotiSysinfo Service menu entry.
You can configure several options. For example, if you want to automatically open it every time you boot your device you can use the Start on boot option.
You can experiment with the different options and see the effect on the app. I found really nice the possibility to choose the color of the bars and the text size.
Here’s how it looks on my Galaxy Nexus. I like that the style of this app is consistent with the notification bar.
Really nice and useful app!
Here’s the link to download the app:
