Sound problems can be subtle - is your phone really ok?
The first call I ever made on mine had so much crackle on the speaker that I had to disconnect. It did this only once more over the next 2 weeks, but call quality was not great compared to other cheaper phones. Still, not so poor that it was unusable - just not very clear. Most people wouldn't say that there was a problem with it.
I also noticed that, upon connecting a call, if I adjusted the volume up or down, there was a crackle, but only on the internal speaker - the external one was fine. This is the symptom you should be looking for. I have come across other E90 owners with the same crackle, who were not even aware that they had a problem.
Mine's gone in to MTN for the second time now (the first time they replaced the speaker, which made no difference).
Once you've handed in your phone, you can email
nokia.support@nokia-care.com, and give them:
- the job card number
- IMEI of the handset
- date of purchase (and all other relevant dates and details)
You can then ask them to make sure that the service centre actually fixes the right problem, which might not happen if you don't.
