I bought a z fold 4 phone from samsung about a year ago and after about 10 months my phone wifi broke down and I sent it to samsung repair center. After about a week I got the phone back and the wifi was fixed, but when I looked at the phone I saw a lot of scratches on the front display. The display protector had been on the phone since I bought it, and it was still on when I sent it to the Samsung repair center, but when I got it back, there was no screen protector on the phone.I immediately contacted the Samsung service center, and they said they were sorry and would fix it if I sent the phone back to them, so I sent it back to the repair center. A few days later, I got an email from them, and when I checked it, they wanted over $170 to replace the face display on the phone. Obviously, the repair center accidentally scratched a lot of scratches on my phone, and I was angry that they wanted money when I was still under warranty, so I called the service center and asked why they wanted money, and they connected me to the repair center and talked to the repair center supervisor. The supervisor of the repair center said that my phone had many scratches from the beginning, which is ridiculous, and demanded more than $170 to fix it. Despite my repeatedly explaining that my phone had a protective film on it and that there was no protective film when I received it, the samsjng repair center manager kept repeating that there were many scratches on it from the beginning and that he could not fix it. In my opinion, Samsung is a company that thinks that it is enough to sell products. I told my friends about it, and they all cursed Samsung a lot. Don't buy any Samsung products.
