I upgraded my Samsung z flip 3 to 4 about two months ago because the screen had so many cracks in the middle hinge. Now, I slipped my phone from the table to the floor and it is totally damaged. This flip phone is so fragile and sensitive as the person who is working in the Samsung repair stores told me when I went them to fix it. Worst of all, it has been only two months and they don't give me warranty repair because I slipped the phone one time and the phone is in total useless. When I had apple phones, I dropped the phone so many times and never had this problem. I am not buying any Samsung phones from now on, so fragile compared to the high prices with deficient services.
