Do you know which model you have. It is hard to tell without looking at pictures of the side of your device. I have the Eken m70003 and screen brightness is its main drawback although everyone else in my family (with better eyes) find the screen adequate except outdoors. Freelunches idea did not work with my model but does work with some apads (where the manufacturer sets max brightness low in order to prolong battery life). Good luck. OT, if other people find your screen brightness adequate you may want to consider doing what I did, going to the opthalmologist / eye doctor.
