I've read a post from a moderator here they do come shipped with a screen protector on them already - similar to how other phone manufacturers do.
Its typically a plastic tpu variant @Mecha but not the in-transit type all Samsung phones come with.
Current Phone > Samsung Z Fold³ 5G.
I would advise not to keep the screen protector it came with on for too long. I took it off and it is really, really thin so doesn't seem that durable.
Mine was so badly aligned I had no choice but to remove it. Very poor in my opinion.
And no clear case as originally shown on the website in the what's in the box pictures/list.
I bought a tempered glass protector and when I put it on you could see a border all the way round it . Thought it was because of the already applied one by Samsung so took both off . Once out the the tempered one back on I still had the same border around and looks *****! The protector is smaller than the screen so can't see why it doesn't fit properly .
Well, I just checked and it does indeed come with an impeccably fitted screen protector. Couldn't say anything about its quality, but it's better than no protection, so it'll do for now. Cheers.
I have had mine on for 8 months since I got this phone, I have bought a.glass screen protector but I'm a big believer in" if it ain't broke don't fix it" and I have never had any problems and I have dropped it several times. So flimsy or not, it works great.
