Einleitung
You can use this guide to replace the buttons if they are broken or sticking. This guide requires you to remove the housing and unscrew a few parts in order to reach the button grouping.
It is best to find a flat, spacious working surface to keep the device level. Also, it helps to place the screws on a magnetic mat upon removal to keep them from rolling away.
