In Google Play settings you can disable auto update of your apps. IOS has the same option. You need to turn off the auto updating so you aren't surprised with a new app one day that totally resets all of your settings without telling you, not to mention it could possible not work with your old firmware, forcing you to upgrade the firmware with no choice. It's not easy remembering all of the settings you worked weeks to fine tune, and when apps update without telling you over night, you wake up to a whole new setup in the app, which often doesn't work as expected. FREEZE EVERYTHING, including your OS upgrades, and you'll never get surprised.
