OnePlus 8T 5G NSA模式下无法通过Telephony获取NR信号强度问询

我尝试获取处于5G NSA模式设备的CellSignalStrength，该模式需同时涉及LTE和NR，因此希望获取两者的信号强度，但不同设备表现不一致：

• OPPO A78 5G（ColorOS，Android 13）可正常获取LTE和NR信号强度；
• OnePlus 8T 5G（OxygenOS，Android 13）虽确认处于5G NSA模式，但仅能获取CellSignalStrengthLTE。

令我困惑的是，Play Store上部分应用可在OnePlus 8T 5G上捕获NR信号强度。
*补充：开启5G SA模式时，两台设备均可正常工作。

我使用Telephony框架获取CellSignalStrength，代码片段如下：

fun requestCellInfoUpdate() {
    //Get the system's TelephonyManager service.
    mTelephonyManager = context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
    
    //Create a TelephonyManager instance for the default subscription ID. (Current Data SIM)
    mTelephonyManager = mTelephonyManager.createForSubscriptionId(getDefault_SubscriptionId(context))
    
    //Request cell info update (Android Q). The result will be handled by the provided callback.
    mTelephonyManager.requestCellInfoUpdate(context.mainExecutor, object : TelephonyManager.CellInfoCallback() {
        
        override fun onCellInfo(cellInfo: MutableList<CellInfo>) {
            // Find the currently registered cell from the list.
            val servingCell = cellInfo.find {  it.isRegistered}
            
            // If a registered cell is found for serving cellular, update the cachedCellInfo list.
            if (servingCell != null) {
                cachedCellInfo = listOf(servingCell)
            }
        }

        //Callback method when there's an error retrieving cell info.
        override fun onError(errorCode: Int, detail: Throwable?) {
            super.onError(errorCode, detail)
            // Handle the error as needed. For example, log the error or display an error message.
        }
    })
}

fun getInfo(): List<String> {

    //Request the current cell information.
    requestCellInfoUpdate() // Update Cell Information on return to `cachedCellInfo`

    var cellId: String
    var cellSignalStrength: String
    var telephonyList: List<String> = emptyList()

    //Check if the cached cell information is available.
    if (cachedCellInfo.isEmpty()) {
        // If not available, set error messages indicating the GPS needs to be on.
        cellId = "Error! GPS must be turned on."
        cellSignalStrength = "Error! GPS must be turned on."
    } else {
        //Extract cell identity and signal strength from the cached information.

        cellId = cachedCellInfo[0].cellIdentity.toString() // index 0 to get only Serving Cell data
        cellSignalStrength = cachedCellInfo[0].cellSignalStrength.toString() // index 0 to get only Serving Cell data

    }
    
    //Add the extracted cell identity and signal strength to the result list.
    telephonyList += cellId // index [i]
    telephonyList += cellSignalStrength // index [i+1]

    return telephonyList
}

鉴于设备处于5G NSA模式，我本应获取LTE和NR的信号强度，但如前所述，OnePlus 8T 5G仅返回LTE信号强度。我最初以为是硬件限制，但因其他应用可在该设备上捕获NR信号强度，故认为存在可行方案。恳请提供在5G NSA模式下准确捕获ss-rsrp和ss-rsrq值的指导。
