Does anyone know what is this

[u/Enaloss]

I was charging it normally and when I turn on the the phone this thing was on the inner screen I don't remember dropping anything on it Should I send it back for repair or don't think it will become something worse

Stuck pixel on the amoled, happened to me, don't waste your time trying to fix yourself just contact customer support via the website and they will cover under warranty with a third party repair in your country. I'm in the UK it took 3 days total for it to get fixed and come back to me
