Dealing with a malfunctioning volume button that randomly adjusts your sound, or a stuck power button? These issues are frustrating but fixable on rooted Android devices. By disabling the problematic hardware buttons and using reliable third-party apps for volume and power control, you can regain full functionality. Note: This requires root access—proceed only if your device is rooted.
As a seasoned Android enthusiast with years of experience tweaking rooted devices, I've successfully resolved these problems on multiple phones, including MediaTek models. Here's how to do it safely.
To disable hardware buttons, you'll edit keylayout files in the system directory. Use a root-enabled file manager like Root Explorer, Root Browser (free), or ES File Explorer—though the latter has ads, so consider alternatives for a cleaner experience.
Step 1: Launch your root file manager and enable Root Explorer mode. Grant permissions, then mount the /system partition as read/write (R/W). Tap Mount R/W and select write access for /system files.
Step 2: Navigate to /device/system/usr/keylayout (or Local > /Device > system/usr/keylayout). Key files include Generic.kl and device-specific ones like mtk-kpd.kl for MediaTek phones. Start with Generic.kl; if needed, check files mentioning Volume or Power.
Step 3: Backup the file first: Copy it and rename the duplicate with a .bk extension (e.g., mtk-kpd.kl.bk). Open the original, tap edit, and search for the button's keycode, like key 115 VOLUME_UP. Comment it out by adding # at the start of the line (include a space after #).
Step 4: Save changes (confirm with Yes) and reboot your device. The button is now disabled—Android ignores commented lines, preventing accidental triggers.
Disabling the button doesn't remove its software function; apps can still trigger volume or power actions. Use Pie Control for gesture-based controls or explore on-screen volume apps for seamless replacement.
