Hi Vitaly,
Can you please advise which apps could be stopped and which are necessary to keep running (if any)?
Fresh installation of 9.1 looks this way:
root@swi-mdm9x28-wp:~# app status
[running] atAirVantage
[running] atQmiLinker
[running] atService
[running] audioService
[running] avcService
[running] cellNetService
[running] dataConnectionService
[running] fwupdateService
[running] gpioService
[running] modemService
[running] portService
[running] positioningService
[running] powerMgr
[running] qmiAirVantage
[running] secStore
[stopped] smsInboxService
[stopped] spiService
[stopped] tools
[stopped] voiceCallService
[stopped] wifi
[stopped] wifiApTest
[stopped] wifiClientTest
[running] wifiService
[stopped] wifiWebAp
Is there more detail description of pre-installed apps available?
Thanks a lot.
Best regards
Mirek
