I just checked my dumpsys info and found this one:
Airplane Mode
mServiceState={mVoiceRegState=3(POWER_OFF), mDataRegState=0(IN_SERVICE), ...
mCellIdentity=CellIdentityGsm:{ mLac=.. mCid=.. ...
mSignalStrength=SignalStrength:{mCdma=CellSignalStrengthCdma: cdmaDbm=.. <-SAME
mBarringInfo=BarringInfo {mCellIdentity=CellIdentityLte:{ mCi=...
mTelephonyDisplayInfo=TelephonyDisplayInfo {network=UNKNOWN, overrideNetwork=NONE, isRoaming=false}
...
mActiveDataSubId=1
mRadioPowerState=0
Normal Mode
mServiceState={mVoiceRegState=0(IN_SERVICE) <- DIFF , mDataRegState=0(IN_SERVICE) <- SAME, ...
mCellIdentity=CellIdentityLte:{ mCi=.. mPci=..
mSignalStrength=SignalStrength:{mCdma=CellSignalStrengthCdma: cdmaDbm=... <- SAME
mBarringInfo=BarringInfo {mCellIdentity=CellIdentityLte:{ mCi=... <- SAME
mTelephonyDisplayInfo=TelephonyDisplayInfo {network=LTE, overrideNetwork=NR_NSA, isRoaming=true}
...
mActiveDataSubId=1 <- SAME
mRadioPowerState=1 <- DIFF
All other settings is same but I think this is very important. Questions:
- Why after Airplane mode
mCellIdentity changed from CellIdentityLte to CellIdentityGsm? It mean modem is works?
- Why
mDataRegState always active? Even if I will disable Mobile data before turning Airplane mode on it will left active. In developer settings always active mobile data is also turned off.
- Why default
Emergency app working in background and why we don't have option to disable it? It using modem anyway? I disabled it only via ADB.
