I was just randomly watching a vide on my phone (A73) and suddenly this hideous neon green line appeared on my phone. I never dropped my phone or it never fell into water. It's clearly a production issue from Samsung as I've read about other complain...
They are charging like a ridiculous amount for it tho. And Samsung Bangladesh isn't even offering it to flagship users. My friend with her S series phone faced the same issue and they asked for like 40k bdt from her to fix the issue
