(1) Applied for：
In some circumstances, the environment light is too bright for the App to correctly recognize the location of the laser spot.

**Notice：Adjust the EV prior tapping the "Measure".
2. Manually recapture the laser spot：

(2) Steps of recapture：
a.) Touch and hold on the recognition circle for 2 seconds till the magnifier pops up.
b.) On the magnifier, move the laser spot to the center of the cross.
c.) Tap "Measure" to recalculate the distance, length or width.
(1) If the magnifier sub-screen covers the corner of object, simply drag it to somewhere else by 2 fingers.
(2) To turn off the magnifier, just double-click the sub-screen by single finger.
