Concerned about the health of your N900? Healthcheck can help you out not only to check your phone for hardware failures, but also to view your system information easily.
Get it off extras with
apt-get install healthcheck
Healthcheck will allow you to view various bits of info, as you can see on the screenshot above, from your IMEI to hardware status. As the app name suggests, this will help you determine whether there’s something wrong with your N900.
You can also check your total memory status in a nice table, GSM information, CPU frequencies, other things, but the best part of it all are various tests you can run to check for hardware issues. Such as the pointer test, to check whether there’s anything wrong with your display.
Having all that functionality, healthcheck is a really good app to keep your phone in a good condition.
