The device, as shown in the picture, has a defect where the internal speaker for calls is not audible. You must turn on the loudspeaker to hear, but the other person can hear you through both the internal and external speakers. The speaker has been changed, but it broke again, and perhaps the replacement was not original. Honestly, we forgot over time whether the internal speaker that was installed was original or not. The phone is for personal use. It was purchased new in the same year of manufacture. Model: iPhone 11 Pro Max Storage Capacity: 256GB Condition: Used
