Android version 7.0 Model Number SM-G930V I updated google play services today. It obliterated my battery life, slowed my phone, and heats the entire thing up. Almost unusable unless plugged into a fast charger constantly. I found the following tutorial for uninstalling updates: Remove updates to the app (Settings > Applications > All > Google Play Services > three dots menu > Uninstall updates). You might need to head to Settings > Security > Device Administrators and disable Android Device Manager first. I can get all the way to Uninstall updates, but when I select that option I get a message that says "Can't uninstall because this package is an active device administrator." I then click "Manage Device Administrators" and am taken to "Phone Administration Settings" menu, where it lists Find My Device and Google Pay as administrators. I cannot disable either of them, as the "deactivate" buttons are greyed out and cannot be pressed. Any advice?
