Is it harmful to disable all receiver's in SD maid?
Actually i wanna disable all of it including"find device" because of GMS Doze i have to disable it after every reboot.
I did disabled every location receiver in SD maid.
I'm not able to say whether it is harmful or harmless. It depends on your device and on your apps. For example in my calendar app I'm not able to disable the location related services, because to each calendar date, you are able to define a location and this was validated by the location service. Maybe you have other apps and it's absolutely no problem for you, but you have to check this on your device. My advice is to make a backup, either Nandroid or myAndroidtools is also able to backup Services, Broadcast Receiver
Activities and Content Provider. If you run in troubles, you can restore the old settings again.
Good luck
