Introduction
The ABXY buttons are important because they are the primary method of controlling inputs to a game or menu. These buttons are easy to take out after taking off the front cover, so they are popular to customize and modify. If you are experiencing ABXY buttons that stick or are unresponsive, it may be time to clean or replace them.
In replacing the ABXY buttons, you will need a Phillips #1 screwdriver, an opening pick, and a pair of tweezers.
If the ABXY buttons (A, B, X, Y, D-Pad, +, –, HOME, and Screenshot buttons) on your YCCTEAM YCC-SW4001 have debris under them, are broken, or are not functioning properly, you can follow this guide to clean or replace them.
