The System X-Ray bar is a handy tool for app developers and curious Fire TV owners to better gauge the state of their hardware. You launch it from a hidden developer tools menu and it displays system information like CPU, memory, and network usage. With the latest 188.8.131.52 software update, Amazon has added in the ability for app developers to display their own custom information in the System X-Ray bar. This makes understanding what an app is doing a lot easier than digging through system log files. For the average Fire TV owner, this addition will go mostly unnoticed, but if you ever find an app you’re using acting strange, you may want to open the System X-ray bar to see if the developer chose to display any information in it that could explain the odd behavior. This feature is too new for any apps to be using it already, but it may start being used in the future.
