To change the brightness on any phone

1.      Hit the settings button, blue button 2nd above the #1 key
2.      Select the settings soft key at the left
3.      Select Brightness and Contrast at the left
4.      I recommend turning the brightness all the way up (Brightness +), and turn the contrast up (Contrast +) before the screen becomes too dark
5.      Finally, hit the Save soft key on the left to save your new settings, then close to exit
