One of the owners of the smartphone said that the battery of the device swelled less than six months after purchase, which caused the screen to detach from the body. When contacted Apple technical support, they refused to replace the device with a new one.
Is it a manufacturing defect?
Many users state that they encountered similar problems and sent their smartphones to service for repair. When the device comes back, the swelling problem disappears and since there is no clear information, it is assumed that Apple replaced the defective batteries with new ones.
