Android LightMeter update

It seems that at least on EVO, the light meter reading is unstable, it could vary up to two steps in the same light situation. Also without the integration sphere the reading is too directional, which could also introduce an error of 1-2 steps. Other than calibration, some sort of alternative approach is needed. I am thinking about giving a guidance EV value table to assist.
