OK,1st few minutes w/the phone were spent disabling bloat & scouring around for a way to disable CheetahMobile's BS & I think I found a way to stop the data mining without a root method:
Go to SETTINGS > LOCKSCREEN > SECURITY > OTHER SECURITY SETTINGS > ADVANCED > USAGE DATA ACCESS & turn off App Source & Smart Manager.
I also turned off Reporting Diagnostic Info,which can be found in SETTINGS >PRIVACY and SAFETY .
Also turned off the options for reporting diagnostics in the T-Mobile's MY T-Mobile app.
Now,back to CHEETAH MOBILE's data mining snoopware:
Yes,it's here,but,since disabling a couple hours ago as mentioned above,if you go to SETTINGS > APPLICATIONS > APPLICATION MANAGER > scroll right to left until you see ALL > scroll down to CheetahMobile CleanMaster SDK & you'll find that is has effectively been disabled,w/no data & not running.
I've even went in the app drawer & selected SmartManager & used it.Then went back to check if Cheetah Mobile SDK was running or,had any data.The app is still inert with 0.00 total data.
