如何让手机的增强型4GLTE开关默认处于关闭状态?

[DESCRIPTION]
MTK默认的版本中,Setting里面的增强4GLTE开关(VoLTE)默认是开启的,如果想要将其默认设置为关闭状态的话请参考如下修改即可:

[SOLUTION]
(1)

package com.android.providers.settings;

DatabaseHelper.java

loadSetting(stmt, Settings.Global.ENHANCED_4G_MODE_ENABLED,ImsConfig.FeatureValueConstants.ON);(两处地方),将ImsConfig.FeatureValueConstants.ON 改为 OFF

 
(2)

alps/device/mediatek/common/device.mk 文件中如下位置

ifeq ($(strip $(MTK_VOLTE_SUPPORT)), yes)

PRODUCT_PROPERTY_OVERRIDES += ro.mtk_volte_support=1

PRODUCT_PROPERTY_OVERRIDES += persist.mtk.volte.enable=1

endif

将persist.mtk.volte.enable=1

修改为 :persist.mtk.volte.enable=0
