I have another smartphone that I can use. I’m just asking if I prefer to send back the new one or keep it.
But I think I shouldn’t take any risks with the smartphone. I looked again phone infor (Settings …) to see if I have the right model, which I do have.
As described in this forum post (Samsung - Galaxy S10+ - beyond2lte - Documentation Suggestions - #9 by Xenthos), this must be the SM-G975F/DS.
