I think you ment LOW, it has low conversation volume. :D
On the other hand, I have a problem with a W810i that is endeed SLOW, it hangs when I give him simple tasks, it hangs when I press the menu button, it hangs when I press the walkman or the home button!
Does anyone have any ideea why? I bought the phone from Orange Romania, and I flashed it with the Greece MEDITERR firmwire.
Other than that, it works great, best phone I've ever had, let's the Samsung D600 & LG Chocolate in the dust!
It didn't had this problem before unbranding, and it doesn't hang continuousely, it hangs for about half second.
Any ideea why?
