There are no problems, everything is okay. The phone was used at home for over 4 years. I don't remember where the box is, but if I find it, I will give it to you. The phone was not used much because the display broke 2 years ago. A few days ago, an original display from another phone was installed. It is smooth and the battery lasts over 6 hours; if you don't believe it, you can check it. WhatsApp call.
