Can't do much about this, because most of the picture has the correct brightness.
You could try some better camera software which 'sees' the over exposed parts too (bracketing) for instance: Camera FV-5
Just try the free version
Samsung Galaxy Note 2 (WW), AOSB 1.3.0 , PhilZ Touch 6, CyanogenMod 11.2.0, Android KitKat version 4.4.2
HTC One X (WW) CWM, ViperX ROM - broken screen
ASUS TF300T (WW, Unlocked, CWM, Rooted JB OTA)
HTC Touch HD 2 T8585 (flashed to Android)
Hitting 'thanks' is completely free and friendly!
