My 5800 reboots on its own

To all having a self shut down problem. ......
Yep, Had the same problem. Phone dying (shutting down on itself) every other minute. Had A fight with Nokia service centre Idiots. Ultimately wrote a letter in institutional pad to the manager, and threatened consumer court action. Now received it back from service center today. Motherboard changed. New IMEI no. Working fine. Cant believe Nokia brought out such a crappy phone. (from AIIMS/ Delhi/India).

So if you have such a problem.... don't quit pestering them till your voice is heard. They are bound by law to do it.

yes.. mine has been diagnosed as PCB(motherboard) problem.. have to change the whole thing ..well except for the casing or so they said. :P

but since my phone is not covered under local nokia warranty, they advised me to send it back to where i bought it or else i better buy a new set rather than pay for the cost to change the PCB since it costs almost the same as buying a new set.

it seems this phone has serious hardware issues...
there's alot of various issues regarding the hardware malfunction.

LCD problem, PCB problem, earpiece problem, battery contact problem etc

When i buy a nokia 5800, its reboots by its own, the problem was the battery that moves a little bit inside the phone.
Its fix changing the battery. I hope this solve your problem.

loose battery and PCB problem are totally different.

It could be the sim card.

I had a 3 year old sim card that kept on making my 5800 reboot.
I replaced the handset, but it still kept on rebooting.

I read on another forum that some older sim card give problems on newer hardware.

So what I did was to replace my sim with a newer 3G one.

It now hasn't restarted for a week..
