Most of your phones switch off when tapped lightly on the side? And you are happy with that? None of my phones have ever done that before. It's certainly not satisfactory to set about making ad hoc adjustments to any product, never mind sticking flammable paper next to a battery. Anyway, thanks for the feedback, case closed.

I was able to replicate the issue, and find the fault myself, so it is off back to Nokia Repairs. It's a known issue with 5800, I read about it on the official Nokia forums, Support surely do not read their own forums. If you hold the phone in your right hand, and lightly tap it into your left hand, it instantly goes off. If you open the back, put your finger on the battery, and just press lightly to any side, it goes off. Problem is loose battery contacts. Either a terrible design, or a manufacture flaw.

You mean chances plural, because they have already had a chance. How many chances do they get under consumer law? I actually think I know what it is. I've googled around and this issue has been posted about by many users, the most commonly accepted fix is to jam a bit of paper in beside the battery to stop it from moving on the contacts. I did that and it worked fine for a day before powering off again, I think that may be the problem - the battery does not fit snug on the contacts. Design/Build flaw. Not sure where that leaves me in the eyes of consumer law though.

Update. The phone has been away for repair, and came back "no fault found" GREAT. Two days later, the phone is STILL switching off and will not come back on without a battery removal. When I went to collect it the salesman said to take it back again if the fault re-occurred, and they would send it away again. But what is the point in that, they already had it for 2 weeks and could not replicate or find a fault that happens daily! This is extremely annoying for a new phone. The fault has been around since new, gradually gotten worse, been away for repair, now 4 months down the line it is quite plainly not fit for use. Advise?

Thanks Jack.

My 2 month new Nokia 5800 music xpress mobile on contract from carphonewarehouse is continually powering down at apparently random moments. The firmware is uptodate. CWH tell me that the phone would have to be sent away for repair. My questions are this. 1. As the phone is only 2 months old, can I request a new phone rather than repair? 2. As I pay monthly should they supply me with a phone while it is away for repair? i.e. I pay monthly for the phone, so if it is faulty through no fault of my own shouldn't they supply a phone, otherwise why should I pay for the period it is away being fixed? Thanks for any advice.
