Tools & Materials

• None required
• Soft microfiber cloth (optional for cleaning screen)
• Stable Wi-Fi connection (optional for updates)

Difficulty

• Easy

Time Required

• 10–20 minutes

Step 1 — Clean the Display Surface

• Wipe the screen with a clean microfiber cloth.
• Remove oils and debris that can interfere with touch sensitivity.
• If using a screen protector, check for air bubbles or cracks that may affect touch.
• A surprising amount of “touch lag” is actually caused by surface interference.

Step 2 — Restart and Clear Temporary System Cache

• Hold Power + Volume Down and select “Restart.”
• After rebooting, go to:
• Settings → Battery and Device Care → Optimize Now
• This clears background processes and resets cached resources.
• A simple restart can dramatically improve performance.

Step 3 — Reset Touch Sensitivity Settings

• Open Settings → Display.
• Toggle Touch Sensitivity off and back on.
• If you’re using a screen protector, leave it enabled.
• This helps recalibrate how the display responds to pressure.

Step 4 — Disable Features That May Slow Down Touch Response

• Go to Settings → Advanced Features → Motions and Gestures.
• Temporarily disable:
• “Palm Swipe to Capture”
• “Lift to Wake”
• Return to Settings → Accessibility → Visibility Enhancements and ensure no filters or delay features are enabled.
• Some gesture features can interfere with precision taps.

Step 5 — Update System Software & Apps

• Go to Settings → Software Update → Download and Install.
• Next, open Galaxy Store and Google Play Store to update apps.
• Performance patches are frequently included in small updates.
• Updates often include touch driver improvements.
