Review on Smartphone Samsung Galaxy A73 5G 8/256 GB, Dual nano SIM, white by Stanisaw Lewczuk ᠌

While using this product, stripes and streaks appeared on the screen, what should I do in such a situation? I would like to know how I should be apparently with a defective phone. I have been using it for less than a month, the phone has not been dropped. There is no physical damage. There isn't a scratch on it.
