Just to let you know I have another N9 64GB handset here, (exactly the same product variant 059J1V4), but purchased from a different store (in Germany).

This second handset does not exhibit the same behaviour at all, and has not crashed yet in around 12 hours, and is working smoothly/cleanly as some others have reported.

It could be a software corruption in the first handset causing the crashing or it could be a hardware level issue. With the second handset I kept the time synchronisation enabled from the beginning, so all Ovi Store downloads/installations worked correctly rather than breaking at the installation stage.

However, in the first handset I experienced some reboots before anything was installed, so that might rule out the 'software corruption from Ovi Store' theory.

At the moment, I have no choice but to keep the second handset and return the problematic first handset to Handtec.

I don't know if that helps anyone, as it's nothing we don't already know.

I would suggest returning the very frequently crashing handsets and purchasing from a different batch.

Thanks
