Fold Z 4 512GB

All mobile screens are completely fine, thank God. But the IC network and SIM card slot are not working; you need to replace them. Buy a spare part called motherboard from AliExpress for 350. And when I open the inner screen completely, it turns off, so you only need to replace the connector. Buy a connector from AliExpress for 11 and take it to a skilled technician who knows how to fix it and will work with you. I don't want to repair it because I already plan to buy an ultra phone.
