Let’s find out in detail below.

1. Causes of Samsung A71 5g SM-A716 Button Not Working

Samsung A71 5g SM-A716 may have unresponsive buttons, stuck buttons, or buttons that don’t register due to common reasons such as:

• Dirt build-up over time:
  Dust or debris can get stuck in the button gaps, making the buttons less responsive or stuck.
• Oxidized button contacts:
  Frequent exposure to moisture or sweat can corrode the button’s contact points, causing poor connectivity.
• Loose or broken button cable:
  Drops or impacts may break or loosen the cable connecting the button to the mainboard.
• Faulty mainboard or control IC:
  This is less common but more complicated — often occurs if the device has been exposed to water or previously repaired incorrectly.
