在通话过程中，一直靠近距离传感器。通话结束时，要求马上点亮屏幕

[android Version]
Android V2.3 （GB,GB2）
Android V4.0, 4.1,4.2（ICS，ICS2，JB,JB2,JB3,JB5）
[DESCRIPTION]
若是在通话结束之后，也一直有物体靠近距离传感器，则Google默认的行为是当没有插入耳机，没有打开扬声器等情况下依旧会让屏幕保持熄灭。若是有相关客制化需求需要通话结束后马上亮屏的话，可以按照以下方式修改。
[SOLUTION]
修改alps\packages\apps\Phone\src\com\android\phone\PhoneApp.java的
updateProximitysensorMode(Phone.State state)函数的最后几行的代码：
将int fags =(screenOnImmediately ?0
werManager.WAIT_FOR_PROXIMITY_NEGATIVE);
改为：int fags = 0；。
