I don’t prefer Samsung Galaxy S III HD Super AMOLED screen due to PenTile display. And Samsung decided to save battery life by lower Samsung Galaxy S3 display automatic brightness values. Yes, Samsung Galaxy S3 display auto brightness is much lower compare to HTC One X. And have poor outdoor viewing due to low maximum brightness too. How to increase Samsung Galaxy S3 display auto brightness? Simple, just install auto brightness mod which available for stock XXALE8 and XXALF2 firmware (at the time of writing this).
