The buttons are not placed evenly and are slow to respond. It is like having a 486 computer in your pocket. Having to wait one or two seconds longer is too troublesome.
I don't know how to change the font size as the text on the display is a bit too small for my eyes.
The size of the phone is not desirable and quite heavy too.
After upgrading the memory card, the phone keeps on complaining of not having enough memory, and insists that I close some programs even though no applications are active.
This phone does not auto-lock its keys, and its alarm function is very limited.
The speaker is not loud enough and voice clarity is just OK. Don't expect to enjoy listening to MP3 songs with this phone, and its earphones just sound slightly better. It has no equaliser and no FM radio.
I bought this phone in the first place because it has good calendar application which can be synchronized to my MS Outlook.
Compared to my previous K700i Sony Ericsson, the loudspeaker function works perfectly. My voice can be heard clearly.
It has good battery life, which can last up to 3 or 4 days with light use.
After using this model for two months, I discovered that the 'joystick' button was really frustrating to use because the 'Arrow Down' button is very close to Button No. 2, even though I have small-sized fingers or thumb. In addition, when I wanted to press the 'Select' button (the center of the 'joystick' button), it worked 80% of the time. It would either go up, left or right!
