You would think after all these years that AT&T would be able to make a phone where you could actually read the display screen. There is no backlight, therefore you almost need a flashlight and magnifying glass to see the print on the display screen. The sound quality and many features are good but if you want to use the caller id feature, you will be disappointed, like me, with the display. With all the technology available today, why couldn't AT&T get the most important feature to work where it's usable to consumers?
