How to adjust the ringtone of Nokia 6600s?

Copy important things. Copy business cards. Then the original password of *#7780# should be 12345. If it still doesn't work after restoring the factory settings, it may be a problem with the speaker. I spent three months showing it, and something went wrong. I haven't bought it for a few days. If not, I will return it and exchange it for another S40.

If it still doesn't work, it may be the speaker. Go to Nokia maintenance department, and suggest you change a model directly. My monitor said it would be repaired in September, and there are no accessories yet.
