“Sadly, it’s nothing new that smartphone companies use DSLR photos to fake phone camera’s capabilities. Samsung did it before, so did Huawei. And I believe many more brands do it, we just haven’t found out about it yet. I’m pretty sure that Samsung at least bought my photo legally, even though I haven’t received the confirmation of it. But regardless, this is false advertising.”
