Pretty handy app, will show you EXACTLY what is/ isn't functional and to some extent shows the strength or weakness of some features. Worth the download just see all the cool sensors and other features that are rarely given much thought too. I was impressed by the Magnetometer, picking up and identifying the polarity on the graph and the strength and movement of the polarity lines was pretty cool.

Wanted to check the basic CPU RAM AND Storage RAM and sensors and chip type/manufacturer also where it was made. and the date of manufacture. I'm using the note9 with 8G CPU ram and 512G storage ram. This is so far the very best cell phone/computer I've had. For "note9" might work with others.... Also try dialing *#0*# this will bring up a very similar test. using both will test every possible basic item on the phone.

Excellent and pretty cool seeing all this information. Especially liked seeing the day the phone was built and the final test containing all of the devices information. Only thing I would have lijed was a little more information on exactly what to do for the test such as the 'dot' test...took me a second or two to figure out what was being tested. Very cool app!
