title: Retrofit + Gson not parsing certain LOWER_CASE_WITH_UNDERSCORES on other devices
body: <p>I am having trouble understanding why when i switch my test device to a Galaxy Tab E, certain Json fields do not get parsed, however when i use General Mobile Tab 8, everything runs successfully. What am I missing here?</p>
  
  <p>here is my service:</p>
  
  <pre><code> // specify gson parse behav
      Gson gson = new GsonBuilder()
              .setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
              .setDateFormat("yyyy-MM-dd")
              .create();
  
      // set http client timeout
      OkHttpClient okHttpClient = new OkHttpClient();
      okHttpClient.setReadTimeout(Constants.SERVICE_TIME_OUT, TimeUnit.SECONDS);
      okHttpClient.setConnectTimeout(Constants.SERVICE_TIME_OUT, TimeUnit.SECONDS);
  
      // get rest builder
      RestAdapter.Builder builder = new RestAdapter.Builder()
              .setEndpoint(baseUrl)
              .setConverter(new GsonConverter(gson))
              .setClient(new OkClient(okHttpClient));
  
      // build
      RestAdapter adapter = builder.build();
