I was at my daughter's game today and it was a pretty sunny day. With it being sunny I noticed something on my Evo. Under the normal blinking light I was able to see 2 little lights. One looked blue and the other looked red. what are these lights for and how do you use them
Thx
What you were seeing is the ambient light sensor, for automatic brightness settings and Infrared sensor for sensing when your face/ear is up to the phone during phone calls so it can turn off the screen to prevent unintended touches. They are not lights nor usable LED's.
Although,
There is an extra, hidden LED, under the speaker grille on the far right, opposite the regular notification LED on the far left under the speaker grille. It is for Wimax notification, it seemed to be included with the final hardware yet went unused by HTC's and Sprint's software. There is an awesome third party application released that re-purposed this unused LED for extra and prolonged notification. It can display 3 colors Green, Orange-ish, and Red.
Check out this thread to learn more. It is an old thread, but will teach you what there is to know:

There have been recent updated to the application from a new contributor which I am not familiar with, but you should be able to hunt that down from the info I have provided (Search Wimax notifier, or hidden Wimax LED). The application is great and can be used with any Evo, even un-rooted handsets.
I mean zero offense, but I would highly recommend you not rooting your phone. At least not yet, you have more to learn young grasshopper. If it means anything to you, I have had my phone for 10 months and still have not rooted it even though I have most of the knowledge and know how. Good suggestions from Youdoofus (ironic name)
