Question Portable PS2 controller

[Ald2pac]

HHi everyone, could you help me solve a problem I'm having? I bought a PS2 portable controller on AliExpress, everything is connected correctly but the right joystick malfunctions; when I push it upwards it functions as a triangle, as shown in the image.

Have you got photos of the chip when installed? Would be helpful in seeing what and how everything is connected.

¿Tienes fotos del chip una vez instalado? Sería útil para ver cómo está conectado todo.

Hi friend, according to the manufacturer it's normal and the problem is solved in the games. Thank you very much for your response, I really appreciate it.
