Returning to Screen 4, only after installed

MIT App Inventor Help

Hi everyone,
I have no idea what information you will need to assist with this problem.

I am making a game. After the gameplay is completed, the app moves forward to a screen that shows the score. From this screen the player hits the "play again" button, and this screen (screen 4) is supposed to close and return to the screen (screen 2) where the player can choose another game to play.

My basic set-up:
Screen 1- Intro
Screen 2- Choose the game level
Screen 3- Play the game
Screen 4- See the score and "Play Again" button, which returns to Screen 2

This worked perfectly when I was using the emulator to see it on my phone, but when I package it as a .apk and download it to my phone, I make it from screen 4 back to screen 2, but then screen 4 keeps coming back up. I can hit the "play again" button (from screen 4), and it will, momentarily, go to screen 2 (as instructed), but then screen 4 will come back on again and show the score again. I can't get screen 4 to stay away, and I cannot move to another game.

Here are my blocks from screen 2:

Please let me know what other information you need to help me solve this.
Thank you,

Sorry, I guess I don't know how to download an image of ALL the blocks on Screen 2 (there are a bunch of them, and they don't all fit in one screen).

Try closing the Screen in Screen4.
That should return you to the Screen where you opened Screen4.

That sounds like great advice, but I tried it already, and it didn't work.
Any other ideas?

So the problem is that I cannot use both the block "Open screen- screen 2" as well as "close screen." If I close the screen it goes to the most recent screen, which was screen 3, NOT screen 2.

There is an entire section of screen switching advice in the FAQ I posted above.

You're the best- thank you! I will read it all.
