I am selling this device as I no longer need it, as it was used as a sub-device. It is SIM-lock free. It had high specs at the time, and the camera is still beautiful. You can also play games on it. Also, it has 6GB of RAM, so apps are less likely to crash! It also has an infrared remote control, so you can control your air conditioner, etc., by installing an app. The battery was just replaced this month, so the battery life is very good. Defect point 1: USB PD charging is unstable Upon disassembly, the terminals were corroded, causing poor contact during PD charging. Normal charging and data transfer were not a problem. HDMI output is also stable. It should be fixable by replacing the terminals. Defect point 2: Screen burn-in There is burn-in at the bottom of the screen (see photo 4). It was not noticeable during normal use, but it may be noticeable when displaying a white screen, etc. Defect point 3: Back panel is a compatible product The glass panel on the back is a compatible product, so it is prone to fingerprints and does not have the docomo logo. The above are the defect points. No claims and no returns!
