I got my first N900 swapped out due to random restarts and is now on my second one, feel like I am running out of luck here :-)

My N900 now and then vibrates with no obvious reason, it can lay on the table not being used and not receiving any sms or anything and then bzzz it vibrates a half<>whole second or so. It dont happen so often but maybe upto a dozen times per day.

Also when surfing the web (wifi or 3g) the browser sometimes seem to get stuck and then the phone vibrates insanely for 2-3 seconds before the n900 restarts itself. No keys/screen etc works once this happens. This havent happend so often but was similar on the previous phone I returned.

Had a few times that screen update (desktop) seemed slow/lagging and phone restarted, maybe related to the browsing error ? (phone gets too much todo so it restarts?)

Being a computer techie I done the basic error elimination checks, unplugged the memory card (8gb sandisk), no other apps where installed etc. Tested with no wifi on vs 3g only etc.

Cant say I find any other logic in this than either theres SW bugs or hw failure, hopefully the first rather than the later.


I browsed this forum up and down but cant say I gotten much smarter by that, yet :-)

Anyone got some suggestions ?
