Inner Front Button Key Flex Cable For Samsung Galaxy S3 Mini I8190 With Touch Sensor

The Inner Front Button Key Flex Cable for your Samsung I8190 Galaxy S3 Mini is the flex cable connecting the inner front button — such as a home key, menu key, or back key — to the motherboard, carrying all input signals from the physical button to the device processor. It is required when the flex has been torn, kinked, or damaged causing button signal failure on your Samsung I8190 Galaxy S3 Mini.

Yes — this replacement is manufactured to the same conductor specification and connector layout as the original flex on your Samsung I8190 Galaxy S3 Mini. Full front button signal transmission and reliable input registration will be restored to factory standard after professional installation.

Not necessarily — unresponsiveness can also be caused by a damaged dome sheet beneath the button, a worn button cap, or a software issue. Inspect the dome sheet and button cap first. If both are intact and the flex is visibly damaged or the connector is loose, the Inner Front Button Key Flex Cable is the correct replacement for your Samsung I8190 Galaxy S3 Mini.

It is a moderate repair requiring the phone to be opened, the display assembly partially lifted, the old flex carefully detached from both the button and motherboard connectors, and the new flex correctly routed and reconnected. Professional installation is recommended for your Samsung I8190 Galaxy S3 Mini.

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Flex cables with physical damage or that have been installed are not eligible for return. For more information, check out SAHII's Return Policy.
