Cingular, now known as AT&T, released the 8525 smartphone in 2006. You may encounter screen problems with the 8525, including calibration, backlight and freezing issues, which you can resolve without submitting your phone for service repairs.
Calibrate
When using the touchscreen, you may find that the item you touch with the stylus is not activated, which happens when the screen is not calibrated. To calibrate the touchscreen, tap "Start," "Settings," "System," "Screen" and "Align Screen." Touch the center of the cross hair that appears on the screen.
Brightness
The screen may look dark if the brightness setting is set too low. Adjust the brightness level of the Cingular 8525 by tapping the battery icon in the top right corner of the screen, and selecting "Menu" and "Backlight." Move the slider to the right to increase the brightness level and to the left to decrease the brightness level.
Reset
Opening several applications at once on the Cingular 8525 may cause errors in the software, which freezes the device and makes the touchscreen inoperable. To clear the errors, press the small "Reset" button on the bottom of the phone using the stylus. The phone will reboot, after which you can use the touchscreen again.
