android 默认关闭增强型4GLTE开关；去掉VT视频通话功能及菜单

Settings.java

 public static final String ENHANCED_4G_MODE_ENABLED =
                Telephony.SimInfo.COLUMN_ENHANCED_4G_MODE_ENABLED;
public static final String VT_IMS_ENABLED =                                              Telephony.SimInfo.COLUMN_VT_IMS_ENABLED;
public static final String WFC_IMS_ENABLED =                 Telephony.SimInfo.COLUMN_WFC_IMS_ENABLED;
 public static final String WFC_IMS_MODE =                 Telephony.SimInfo.COLUMN_WFC_IMS_MODE;
 public static final String WFC_IMS_ROAMING_MODE =
                Telephony.SimInfo.COLUMN_WFC_IMS_ROAMING_MODE;
public static final String WFC_IMS_ROAMING_ENABLED =
                Telephony.SimInfo.COLUMN_WFC_IMS_ROAMING_ENABLED;
 

方式一：DatabaseHelper.java

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

方式二： device/mediatek/common/device.mk 

#WFC feature（wifi calling）
ifeq ($(strip $(MTK_WFC_SUPPORT)),yes)
  PRODUCT_PROPERTY_OVERRIDES += persist.vendor.mtk_wfc_support=1
  PRODUCT_PACKAGES += ipsec_mon
endif

#VOLTE feature（电话功能）

ifeq ($(strip $(MTK_VOLTE_SUPPORT)), yes)
  PRODUCT_PROPERTY_OVERRIDES += persist.vendor.volte_support=1
  PRODUCT_PROPERTY_OVERRIDES += persist.vendor.mtk.volte.enable=1
endif

persist.vendor.mtk.volte.enable=0  默认关闭volte功能

SIM卡 VoLTE 菜单 开启/关闭状态默认值修改

在 frameworks/base/telephony/java/android/telephony/CarrierConfigManager.java 文件中修改以下参数即可：

       sDefaults.putBoolean(KEY_ENHANCED_4G_LTE_ON_BY_DEFAULT_BOOL, true);

//true：默认开启volte；false：默认关闭volte

        sDefaults.putBoolean(KEY_HIDE_ENHANCED_4G_LTE_BOOL, false);

//true：默认隐藏volte菜单；false：默认显示volte菜单

去掉VT视频通话功能及菜单，默认开启VoLTE电话功能和wifi calling功能及菜单

修改frameworks/base/core/res/res/values/config.xml

<!-- Flag specifying whether VoLTE, VT and WFC is available on device -->
<bool name="config_device_volte_available">true</bool>
<!-- remove vt function start {@ -->
<bool name="config_device_vt_available">false</bool>
<!-- meig:jicong.wang remove vt function end @} -->
<bool name="config_device_wfc_ims_available">true</bool>
