I am looking for a fix but for now you have to sacrifice Shealth if you want VoLTE working on BTU firmware. Flashing full BTU firmware back is restoring Shealth functionality. UPDATE - After flashing back DQB3 bootloader VoLTE stays and Shealth start working So flash DQB3 bootloader and DQB1 cp file at the very end to get everything working!!

Android 6.0 and higher include a capability for privilegedapps to provide carrier-specific configuration to the platform. Thisfunctionality, based on the UICC Carrier Privilegesintroduced in Android 5.1 (Lollipop MR1), allows carrierconfiguration to be moved away from the static configuration overlays and givescarriers and OEMs the ability to dynamically provide carrier configuration tothe platform through a defined interface.

A properly signed carrier app can either be preloaded in the system image,installed automatically, or manually installed through an app store. The appis queried by the platform to provide configuration for settingsincluding:

• Roaming/nonroaming networks
• Visual voicemail
• SMS/MMS network settings
• VoLTE/IMS configurations

Note: This app must be signed with thecertificate that has a matching signature to one on the SIM. See How is privilege granted to acarrier app for details.

The determination of what values to return is entirely up to the carrier appand can be dynamic based on detailed information passed to the app through theplatform.

The key benefits of this approach are:

• Dynamic configuration - Support for concepts likenon-MCCMNC derived configuration, for example,mobile virtual network operators (MVNOs) or customer opt in to extra services.
• Support for devices sold through any channel - For example, anopen market phone can be automatically configured with the rightsettings by downloading an app from an app store.
• Security - Privilege to provide this configuration isgiven only to apps signed by the carrier.
• Defined API - Previously this configuration was storedmostly in internal XML overlays within the framework and not through a publicAPI. The carrier config API in Android 6.0 is public and well defined.

How it works

Loading the config

The carrier configuration supplied by this feature is a set of key-value pairsthat change various telephony-related behaviors in the platform.

The set of values for a particular device is determined by querying thefollowing components in order:

1. The carrier app (this is optional, but it's the recommendedlocation for additional configuration beyond what exists in the Android OpenSource Project (AOSP))
2. The platform config app bundled with the system image
3. Default values, hardcoded into the framework (equivalent to the behavior priorto Android 6.0)

Important: If a value for a particular keyis returned at any stage, the first value found takes precedence over thefurther stages.

The platform config app

A generic platform config app is bundled with the system image. This app can supplyvalues for any variables that the regular carrier app doesn't. The platform configapp can be found (in Android 6.0) in: packages/apps/CarrierConfig

This app’s purpose is to provide some per-network configuration when a carrierapp isn't installed, and carriers/OEMs should make only minimal changes to itin their own images. Instead carriers should provide the separate carrier appfor carrier customization, allowing updates to be distributed through avenues suchas app stores.

How privilege is granted to a carrier app

The carrier app in question must be signed with the same certificate found onthe SIM card, as documented in UICC Carrier Privileges.

What information is passed to the carrier app

Volte File Download For Android Apk

The carrier app is supplied with the following values, enabling it to make adynamic decision as to what values to return:

• MCC
• MNC
• SPN
• IMSI
• GID1
• GID2
• Carrier ID

For more information on integrating carrier IDs, see Integrating carrier IDs with CarrierConfig.

When loading the carrier config occurs

The building of the list of key value pairs occurs:

• When the SIM is loaded (boot, or SIM hot swap)
• When the carrier app manually triggers a reload
• When the carrier app gets updated

See the android.service.carrier.CarrierService#onLoadConfig()reference for more details.

Note: The platform caches carrierconfiguration bundles and loads from the cache for SIM state changes. This isto speed up boot and SIM hot swap. It's assumed that without a package updateor an explicit notifyConfigChangedForSubId

, the config bundle hasn'tbeen modified.

Using the config

When the configuration is built, the values contained within it are usedto set various values of system configuration, including:

• Internal framework telephony settings
• SDK-returned configuration values, for example, in SmsManager
• App settings like VVM connection values in the Dialer

Configuration keys

The list of keys is defined as part of the public SDK in android.telephony.CarrierConfigManagerand can't change within the same API level. See the table below for a summary of keys.

Building the app

Creating the app

Your app must target the Android 6.0 API level (23).

Declaring a class that overrides android.service.carrier.CarrierService

1. Override onLoadConfig to return the values you wish tosupply based on the service.carrier.CarrierIdentifier objectpassed.
2. Add logic to call notifyConfigChangedForSubId in scenarioswhere the carrier configuration may change over time (for example, when theuser adds extra services to their account).

An example is below:

For more details, see theandroid.service.carrier.CarrierServicereference.

Naming the class in the manifest

An example is below:

Signing the app with the same certificate on SIM

See UICC Carrier Privileges for the requirements.

Adding APNs with a carrier app

To add APNs programmatically from a carrier app (for example, during SIMactivation), useContentResolver APIs to add APN items to a content provideridentified by the URIandroid.provider.Telephony.Carriers.CONTENT_URI.For more information about the table structure for the content URI, seeTelephony.Carriers.

For more information, see APN and CarrierConfig.

Testing the app

When you've built your configuration app, you can test your codewith:

• A SIM containing a valid certificate signature
• A device running Android 6.0 and later, for example an Android device
