Josep sent me a link to a thread on BBForums where guru John Clark spotted a cool Device Hardware Test knowledgebase article. Essentially its a built in application that has been around since 4.2 or so that has not received much attention. I remember reading about it on the forums a bit back but this is the first time I have seen anything about it officially. It includes tests for your:
You just select the tests you want to run. You can access the test menu by going to your homescreen and then going to Options>Status and typing in the word test.
I have never really caught anything wrong on the test but I guess people always like to learn new hiddent tricks. It reminds me of the cell tower diagnostic application on old Nokias…
Thanks DavidB for also sending this in!
