FAKE s9+ info needed

Hello ,

I have a problem I'd like to ask you a question about politely.

As I know now, and you probably also know, the real S9+ has a sled, which allows you to insert a SIM card and a memory card at the same time.
With my fake smartphone, which I bought without much thought at a flea market, I can see the opening but I don't have that sled at my disposal.

My question is if you could tell me more about the manufacturer by means of 2 attached pictures of the back of my phone in this mail.
This might help me to get some information there.

I hope that this is not too much to ask of you and thank you very much for all your help.

With polite greetings !
