Not sure how to ask my gf F25 if she went through my phone. I am a 27M (iPhone)

Hey all. I’ll keep this short and sweet. I got an amazing gf. Literally the most loyal and trustworthy girl I know. But something I can’t get over is this; so today we were hanging out. We went to see a movie and before the movie started my last apps open were Instagram, TikTok, and messenger was the very last app I was using. The movie started so I gave her my phone to put in her purse.

After the movie was done we both went to use the bathrooms and she had my phone. Which I didn’t care bc she has my passcode and I set up face id for her so she could use my phone when I’m driving to open the music apps n stuff while she’s passenger princess.

I have never had anything to hide on my phone which is why I don’t care she has access to it. But when I got my phone from her (my phone is an iPhone) I went to swipe up to use my last apps n stuff but there were no apps opened meaning they were all force closed. This is why I’m not sure if she went through my phone while she was in the bathroom and she maybe force closed them because I did not do that. Am I trippin and would that happen on itself? Because I thought that would only happen if someone manually force closed them or not.

This is more so me being upset that she would go through my phone when she knows I have nothing to hide and being sneaky about it. What do yall think?
