Found a couple of apps for Android devices both phone and and tablet. This first one is really awesome. If u were a jailbreaker with the iphone, this may look very familiar, but a lot more is involved here. Download a free app called Cool tool - system stats by Deviantstudio. As you can see from the below photos (it is the orange text at the top middle of the screen), it allows you to display system stats in both graphical and text. But here is where it gets good. You can move this anywhere you want. You can display nearly any setting. Alter colors, use only graphs, change the names and how things are displayed. These pics are from a tablet, but I have this on my phone as well. I just limit the amount of data to fit in a smaller amount of space. It is a free app AND it is also available for Amazon Fires.
