I have a samsung gamepad
The button with one dot does not always respond. For example when I'm playing 'Asphalt 8' car racing game the one dot button is the acceleration button therefore for the most part i hold this button down to maintain acceleration. Half way throughout the game i will lose the acceleration and will need to press the button again for acceleration to register.
I've tested with an alternative button and this doesn't have the issue therefore i believe it's hardware related.
What can I do to fix this?
