Frequently Asked Questions

Is this flex compatible with all colour variants of the Galaxy A25 5G?
Yes, the ribbon is compatible with the SM-A256B model, and the yellow finish should be selected to match the external button of the same colour.

Does replacing the power button flex solve issues where the screen does not light up when pressing the key?
If the mobile phone vibrates or charges but the button gives no response when pressed, the fault is usually in the flex, provided the external physical key is not stuck.
