AC Question
So I have lately I have bought a Chinese Smartphone and when I looked at Settings -> Apps -> All some of the apps have a full access to my smartphone which is rather scary, can someone please help me identify which service/app shouldn't have a full access to my phone and also is there a website in which I can type the name of a service/app and it would tell me which permission it requires ? So this is the list:
Atci_service
BSPTelephonyDevTool
com.mediatek
com.mediatek.batterywarning
Common Data Service
EngineerMode
Factory Mode
FotaProvider
Fused Location
Google Account Manager
Google Play services
Google Play Store
Google Services Framework
Input Devices
Key Chain (A lot of permissions)
MmsService
MTK Thermal Manager
Phone
Phone/Messaging Storage
Schedule power on & off
Settings
Settings Storage
Shell
SIM Tool Kit
SmartcardService
System UI
UpgradeSys
User Dictionary (Why does it have a full access to my SMS/MMS and full network access (?)
YGPS
Search Application Provider
Google Contacts Sync
Google Backup Transport
Google App
Very Suspicious Services/Apps:
MTK Android Suite Daemon (e.g it can read phone status and identity or do everything it wants with a SMS or MMS (?) )
MTK NLP Service (What is this and what does it do
MTK Thermal Manager (Why does controller for a battery needs to have a full access to Android (?)
MTKLogger (Is this a spyware (?)
Omacp (e.g it has access to a "Modify secure system settings" or can do whatever it wants with either phone call or SMS/MMS.
Phone (I have two of them and the first one have handful of permissions where the second one has a full access to Android
(?)
Shell (What is this ? It mainly has access to " access extra location provider commands, interact acreoss users etc, is it possible that this might be a backdoor ?)
UpgradeSys (I have never noticed it on another smartphone, same as Shell.)
Normal (What is this app ?)
LocationEM2 (Again, what the hell is this app ?)
What I don't understand is that many apps/services has permissions which they shouldn't have
.... I have tried to for example find out what's LocationEM2 or MTKLogger but I have ended up with nothing ....
I was also thinking about rooting the device and install some firewall to block incoming connections to such apps/services which are suspicious or what's better remove such permissions. Also I know that Common Data Service can serve as a backdoor. Also I didn't connected this device to a Wi-Fi as I want to sort this stuff out first and it's a bit scary what's going on underneath the mask in this smartphone with services/apps and I must admit I'm a bit concerned about credentials used on such device. Also what's weird is that most of the services/apps I can't disable when for example on Sony Xperia M2 I could do it with most of them.
Can someone give me a hand here please ?
Kind Regards
