Pulled Over In Ga, Officer Took My Phone And Scrolled My Photos Without Consent. What Can I Do Now?

Location: Georgia, USA.

Last week I was driving home from work on a 4 lane road just outside a small city. It was around 9 pm, light traffic, clear weather. I wasnt on my phone, it was in a mount on the dash because I use it for music and GPS. I got lit up by a state trooper. I pulled over, turned the radio down, kept my hands on the wheel, all the usual stuff. He came up on the passenger side and said he clocked me going 64 in a 55. I honestly thought I had been at the limit but I wasnt going to argue on the side of the road. I gave him my license and proof of insurance when he asked.

Then he asked if I had been texting. I said no, my phone was just running Spotify and Maps. He told me to hand him the phone. I kind of froze and said "I'd rather not, there's personal stuff on there." He said "If you don't have anything to hide you wont mind" and reached in through the open window and took the phone out of the mount himself. Screen was already on because of the GPS. He hit the home button, opened my messages and instagram, then the photo gallery. I was in shock and didnt say anything, which I am kicking myself for now. He scrolled through a bunch of pictures, including a folder with some very intimate pics of me that I had sent to my partner. At one point he actually laughed and said "well alright then" and put the phone face down on my lap.

He went back to his car for a few minutes and came back with just a written warning for the speed. No ticket, no phone related citation, nothing about DUI, nothing. Before he left I said "Are you allowed to go through my phone like that without a warrant" and he just smiled and said "Have a safe night" and walked off. The whole thing has been eating at me. I feel super violated and also embarrassed that some random cop has seen my nudes now. I’ve been replaying it in my head and wondering if I should have pushed harder in the moment, but I was honestly scared of making things worse.

I dont know if this matters but I have no criminal record, was completely sober, car was properly registered, etc. My phone is not password protected when the screen is active but it does lock after a minute or two. I did not give verbal consent, I also never explicitly said "no, you cant look," I just said I’d rather not and then he physically grabbed it.

My questions: Under Georgia / US law, was what he did even legal, or did this cross into an illegal search of my device. If it was not legal, is there any realistic remedy here since I didnt get a ticket or criminal charge out of the stop. Is it worth filing a complaint with internal affairs or a civil rights organization, or am I just signing myself up for trouble with local law enforcement if I put my name on anything.
