Android PBAP тянет CCH_PATH только 50 данных

Question

Код Android 7:

public static final String CCH_PATH = "telecom/cch.vcf";
CallLogPullRequest ichCallLog =
            new CallLogPullRequest(mContext, BluetoothPbapClient.CCH_PATH);
    addPullRequest(ichCallLog);

@Override
public void onPullComplete() {
mEntries.size() max 50
        Log.d(TAG, "onPullComplete with " + mEntries.size() + " count.");
  }

Почему mEntries.size () max 50?
