Android 8.1 설정 에서 선 호 하 는 네트워크 유형 은 LTE 가 없습니다.
60616 단어 android
RK3399 + Android 8.1
질문:
설정 > 더 많은 > 모 바 일 네트워크 > 첫 번 째 네트워크 형식 옵션 은 3G 와 2G 만 표시 되 고 LTE 가 부족 하 며 자체 모듈 과 SIM 카드 는 LTE 를 지원 합 니 다.

config_enabled_lt 의 값 은: | -- packages / services / Telephony / res / values / config. xml 입 니 다.
<bool name="config_enabled_lte" translatable="false">falsebool>
기 존 코드 (이하 RK 3288 Android 7.1) 에서 이 값 은 true: | -- device / rockchip / common / overlay / packages / services / Telephony / res / values / config. xml 입 니 다.
<bool name="config_enabled_lte" translatable="false">truebool>
따라서 configenabled_lt 의 값 을 true 로 바 꾸 면 LTE 를 표시 할 수 있 습 니 다.
