Guys, Why did my guy friend hold my phone?

So basically we were at youth group and we were sitting next to each other and i left my phone on the chair when service ended and he went to grab his chair, my chair and someone elses which he normally does even if he’s not sitting next to me. So he grabbed my phone and put it in his pocket and i guess he noticed i was looking for it and told me from a couple feet away that he had it and i was like “ok”, all i cared about was that it wasn't lost and it was safe. But let’s take inventory here; he could’ve put it inside my open bag, or even laid it on top. I have never seen him do this with any other girl. Is this something guys do when they have feelings for a girl, idek. It’s a small thing but am i overthinking this? Also a couple weeks a go he told me he was unsure about our friendship and saw a possibility of sorts and i said i did too but ultimately we agreed to be friends because it wouldn't work out longterm, we agreed were better as friends. Its kind of been an adjustment to getting back to normal and seeing him strictly as a friend again, i just didn't want anything to be awkward and last Wednesday which is when the phone thing happened and he sat next to me, was also the second time i had seen him since our convo. It did not feel awkward at all and i loved that. Anyways sorry for such extended context, but what do y'all think?
