Review on Samsung Galaxy A21s A217M 64GB Dual SIM GSM Unlocked Android Smartphone (International Variant/US Compatible LTE) - Blue: Advanced Features and Reliable Performance by Yen Hong Cam ᠌

I bought a phone, on the 13th day I began to behave strangely. He dials the code with zeros, opens applications himself, writes SMS, can select any contact and scribble SMS "iiiiiiiiiiii", he enters the viber himself, everything is the same. I'm in shock ! I hold the bodies in my hands and watch everything from the side! I can’t stop it. This happens once a day, then everything is fine. I went to the salon where I bought the phone, they advised me to remove everything to the factory settings, the seller said it might be a virus. to hand it over for repair. The phone was not dropped or wet.
