Проблема с этим кодом в Whis Im Im Im 4g LTE Network (Источник: G-NET Track Pro Info) Эта сеть как 5G NR (NSA), потому что (я не знаю, почему), overdetype == TelephonyDisplayInfo.Override_network_type_nr_nsa in 4g (lte) и 5G (Lte) и 5G (LTE) и 5G (LTE) и 5G (Lte) и 5G (LTE) и 5G (LTE) и 5G (LTE) и 5G (LTE) и 5G (LTE). (NSA) .. < /p>
Основная проблема для обнаружения NR (NSA) состоит в том, что в этом случае нет NR -клеток .. < /p>
Как найти, где я нахожусь в 5G NR (NSA) или 4G (LTE)? Приложение. < /p>

public static final int OVERRIDE_NETWORK_TYPE_NR_NSA = 3;

Кроме того:*#*#4636#*#* меню Показать nr_nsa как для голоса, так и для сети, но G-Net Track Pro отчеты как 4G LTE, а не 5G NR (NSA), и я думаю, что это нормально, потому что нет логотипа 5G в течение жизни.>
