How to get back to older app version?

[luap123]

Ok guys a qwick question my phone for some weird reason updated the stock Samsung calculator to the latest version and the version I was on was much better in looks and usage.and I have auto update off for play store and generally all software updates blocked, so not sure what happened.

So the question is if I factory reset my phone I'll get the old factory version back right?but what will happen when I reinstall my back up will that be the new version i dont want or will it stay on the factory version I like as long as I make sure auto updates are off in the play store and galaxy store?

If the update was an OS one, then nope, restoring to 'factory' default will have the updated new OS image. If the app was updated as a standalone app (something you can uninstall), you can try to find an older version and install that manually (side-loading), but most official repositories will have the newest version.
