Introduction

In this guide, we’ll show you how to safely replace the action buttons on your Anbernic RG35XXSP handheld console.

Common Causes

Delayed or inconsistent input during gameplay
Buttons feel stuck, soft, or don’t spring back
Some buttons no longer respond at all
Physical wear or damage to the button caps

This guide walks you through each step of the replacement process, with helpful tips to ensure a smooth and effective repair.

Before you begin the repair, make sure to turn off the game and unplug from the charger.
