Fix Galaxy S6 Back Button Not Working

Updated 7 November 2026 · Standard formula, shown below

If your Galaxy S6’s back button has stopped responding, you’re not alone. This guide walks you through practical fixes, from simple software tweaks to hardware checks, so you can restore full navigation without a trip to the repair shop.

What You’ll Need

A soft, dry microfiber cloth
A toothpick or wooden cocktail stick (for cleaning)
Isopropyl alcohol (70% or higher) – optional, for stubborn grime
Access to your phone’s Settings menu (if the screen still works)

Step-by-Step

Restart your phone. A simple reboot clears temporary software glitches that often cause unresponsive buttons. Press and hold the power button, then tap “Restart.” If the screen is frozen, press and hold Power + Volume Down for about 10 seconds to force a restart.
Clean the button area. Dirt, dust, or moisture can block the capacitive sensor. Gently wipe the back button (bottom-right of the home button) with a dry microfiber cloth. For deeper grime, slightly dampen the cloth with isopropyl alcohol and wipe again. Use a toothpick to carefully dislodge any debris around the button’s edges.
Check for screen protector interference. A poorly aligned screen protector or a thick case can cover the button’s sensor. Remove the case and any screen protector, then test the button. If it works, reapply the protector carefully or consider a different one.
Update your software. Go to Settings > About Phone > Software Update. Install any available updates. Samsung periodically releases fixes for touch and button issues.
Boot into Safe Mode. This disables third-party apps that might be conflicting with the button. Press and hold the Power button, then when the Samsung logo appears, press and hold the Volume Down button until the home screen appears (look for “Safe Mode” in the corner). Test the back button. If it works in Safe Mode, a downloaded app is the culprit.
Uninstall recent apps. If Safe Mode fixed the issue, uninstall apps you installed around the time the problem started. Go to Settings > Apps, select the app, and tap “Uninstall.”
Clear system cache. Corrupted cache data can cause button lag. Turn off the phone. Press and hold Volume Up + Home + Power until the recovery menu appears. Use Volume keys to navigate to “Wipe cache partition” and press Power to select. Reboot the phone after the process finishes.
Factory reset (last resort). This erases all data and restores the phone to its original state. Back up your files first. Go to Settings > Backup & Reset > Factory Data Reset. Follow the prompts. Only do this if other steps fail, as it’s time-consuming.

Common Mistakes

Skipping the restart. Many users jump straight to factory resets, but a simple reboot fixes a surprising number of glitches.
Using liquid directly on the button. Spraying cleaner directly can seep into the phone and cause more damage. Always apply to a cloth first.
Ignoring Safe Mode. If an app is causing the problem, you might waste hours on other fixes. Safe Mode is the quickest way to identify it.
Forgetting to back up before a reset. A factory reset wipes everything. Without a backup, you lose photos, contacts, and messages permanently.

Tips

Use the on-screen navigation bar as a temporary workaround. Go to Settings > Display > Navigation Bar and enable the on-screen buttons. This gives you a back button at the bottom of the screen while you troubleshoot.
Check for physical damage. If the phone has been dropped or exposed to water, the button may be physically damaged. Look for cracks or discoloration near the button.
Keep the button clean regularly. A quick wipe with a microfiber cloth every few days prevents grime buildup.
Use a case with a raised lip. This protects the button area from direct impact if you drop the phone.

Troubleshooting

If the button still doesn’t work after trying all steps:

If it works in Safe Mode but not normally: A third-party app is the likely cause. Uninstall recently added apps one by one, testing the button after each removal.
If it works after a factory reset: The issue was software-related. Restore your backup, but be cautious about reinstalling the same apps that might have caused the problem.
If it never works: This points to a hardware failure. The capacitive sensor or the digitizer may be damaged. Contact Samsung support or a certified repair center for a professional assessment.
If the button works intermittently: This often indicates a loose connection or early hardware failure. Try cleaning again and avoid pressing too hard. Backup your data regularly in case it fails completely.

Frequently Asked Questions

Why is my Galaxy S6 back button not working?

The most common causes are software glitches, dirt or moisture on the button, a faulty screen protector, or a hardware issue like a loose connection or damaged digitizer.

Will a factory reset fix the back button?

It can, if the issue is software-related. A factory reset clears all settings and app data, which often resolves conflicts. However, if the problem is hardware, it won’t help.

Can I use the phone without the back button?

Yes, enable the on-screen navigation bar in Settings > Display > Navigation Bar. You’ll get virtual back, home, and recent buttons that work just like the physical ones.

How do I clean the back button safely?

Use a dry microfiber cloth. For stubborn grime, slightly dampen the cloth with isopropyl alcohol and wipe gently. Never spray liquid directly on the phone.

Is the back button hardware or software?

It’s a capacitive button, meaning it senses touch. It can be affected by both software (glitches, app conflicts) and hardware (dirt, damage). The steps above help you determine which.

How much does it cost to repair a Galaxy S6 back button?

Repair costs vary by location and whether the issue is the button itself or the screen/digitizer. Contact a local repair shop for a quote. It may be more cost-effective to consider a replacement phone if the repair is expensive.
