Hmm that's really poor customer service on both ends. Though Amazon's return/replacement policy only lasts for 30 days, after that it's the 1 yr manufacturer's warranty from Nokia that is in place (though in reality it starts the moment you get your device). Though I'm not advising waiting for the return policy to expire then using the warranty since there's no guarantee Nokia will accept it. Though they should since it is a reproducable defect.

I'm inclined to follow your non-advice. ;) I'm reluctant to give up a (mostly) working n900, to wait an unknown length of time, to pay unknown addition cost, for a second device which may or may not have the same problem. I'd like to hold on to the one I've got, live with the hassle of having to use a headset for phone calls, and hope to get this one repaired under warranty once the current n900 fever dies down. The whole situation feels like it's going to be a gamble on my part either path I take.

^ how long did it take? i just sent mine out for faulty ear piece, and i really hope they send me a new one and not just reject it back to me, which then would just force me to use a headset to all calls just to hear them other then using speaker phone
:mad:

LOL, what email ????

No information from them (though out of habit I did chase) and the only thing was that a new order was setup for me, which was waiting for stock to be allocated to it after they had the phone for a week.

Re: N900 Microphone / Mic Issues: Dead on Arrival (DOA), Not Working, Intermittent Failures

Keep chasing them for info. Nothing was volunteered to me unfortunately. I kept phoning them every 2 days for progress.

maemoexperts
Serial Number 015476

pwannell
Serial Number 015297

nuknuk
Serial Number 015481

FC_
Serial Number 012679

douglas
Serial Number 008154

bbrindle
Serial Number 008477

FYI those want to find out the serial number,

The IMEI format is as follow (example only): 35007752-323751-3
The bit in bold is the N900's unique serial number.

First 8 digits = Type Allocation Code (device name + region etc.)
Last digit = Check Digit

---------------------------------------------------
Serial Number 015757

Arrived and powerd up on 30 Nov09
- Mic was dead on arrival.
DTMF tones can be sent from number pad
External earpiece and mic work OK
Bluetooth headset works OK
Has been fully reflashed with the Flasher - internal mic still dead.

Diasasembly video here:

Seems to show that, in common with other Nokia phones, mic is a module that relies on presure contact with the motherboard. Could be a problem with a poor connection at this location (resist not cleaned off properly etc) or wrong type of microphone module used.

May be some brave person will have a go at checking their mic connection:)

Uh, do you guys not realize giving your IMEI and hence serial number allows crooks to clone your devices? I advise you remove them for your protection.

how is that possible cloning a device? to make it look like the actually thing ? cosmetic is not the software I guess. And I think Maemo5 is open therefore it would be easier to clone I guess.:confused:

Cloning the handset is not the same as cloning the SIM card from what i understand...
an IMEI is more like a MAC address i think.

IMEI is a sensitve piece of information. Take heed and realize this is a freely travelled site. Anyone with malicious intent could come and steal from you, but only if you help them.

Now that we are past the holidays, Amazon is suddenly being more cooperative. There are going to send me a replacement after all. Here's hoping the microphone in the new one works.
