I have aweful sound quality on the my Orange SPV M600; the same problem as I had the old SPV E200. The sound is fuzzy and distorted - especially if the speaker is on loud. Others on this forum have complained of the same.
Please complete the poll so we can see if there are just a few faulty batches, or if its to do with the ROM, or whether the handset is just flawed.
This poll is about sound quality during calls, using the inbuilt speaker and not via a headset.
