Can I fix my rooted S3 on my own?

[AC Question]

About a week ago I rooted my Samsung Galaxy S3 neo. I regret that I did that because now every Google app (Drive, YouTube, Google play, etc.) isn't working. And I game didn't work as well so I reinstalled it and it works but lost everything in the app. So I wanted to get everything back by using Google Play but since that isn't working I can't do anything. Is there a way to fix my phone without Sasmung yelling at me for rooting my phone?

1. Rooting won't affect those apps since they evidently didn't need root to run, so they never call su (which is the only change when you root - if the rooting app was written properly), so they don't know if the phone is rooted.

2. Samsung will charge you for having rooted the phone - IF they even decide to repair it.

3. Just flash a stock ROM to the phone (see [Samsung] How to flash Stock ROM via ODIN). It may look scary, but by the 5th time you flash a ROM, you'll do it during a ball game so you have something to do. It's boring.
