How to Fix Galaxy S23 Display Not Waking from Sleep

If your Galaxy S23’s display stays black and unresponsive when you press the power button or double-tap the screen, the problem is almost always software — not hardware. As of 2026, the most common culprits on One UI 6.1 and later are aggressive battery optimization, disabled wake gestures, a proximity sensor misfiring, or a glitch introduced by a system update. This guide covers every fix in order from quickest to most drastic, so most readers will be done after the first two steps.

What Causes the Galaxy S23 Display to Not Wake from Sleep?

Before diving into fixes, it helps to know what’s actually stopping your screen from turning on. The most common causes include:

Ultra Power Saving or App Power Saving mode — These modes aggressively restrict background processes and can prevent the display from waking on command.
Lift to Wake / Double Tap to Wake disabled — These gesture features are enabled by default, but system updates occasionally reset them to off.
Proximity sensor interference — The S23’s proximity sensor (located at the top of the display) can mistakenly detect your phone as “in pocket,” blocking the screen from turning on.
One UI 6.1 touchscreen bug — Samsung confirmed a bug in the One UI 6.1 update where the Google app could cause the touchscreen and wake gestures to become unresponsive. Samsung has since patched this, but devices that haven’t updated may still experience it.
Always On Display (AOD) set to “Tap to show” — If AOD is configured this way, the screen appears off unless you tap first, which some users mistake for a wake failure.
Stuck power state or frozen system process — A simple force reboot usually clears this.
Faulty power button or bad OLED panel — If none of the software fixes work, hardware is the cause.

Fix 1: Check Lift to Wake and Double Tap to Wake Settings

This is the most overlooked cause. One UI 6 and 6.1 updates have been known to reset wake gesture settings.

To re-enable Lift to Wake:

Go to Settings
Tap Advanced features
Tap Motions and gestures
Make sure Lift to wake is toggled on

To re-enable Double Tap to Wake:

Go to Settings
Tap Advanced features
Tap Motions and gestures
Make sure Double tap to wake is toggled on

Note: Double tap to wake requires two rapid taps in quick succession using one finger. A slow double-tap or using two fingers will not register.

Fix 2: Disable Battery Optimization Modes

Ultra Power Saving mode and per-app battery optimization are the #1 cause of display wake failures on the Galaxy S23. These modes shut down display-related processes when the screen is off.

To turn off Ultra Power Saving:

Go to Settings
Tap Battery and device care
Tap Battery
If Ultra power saving is enabled, tap it and turn it off

To disable per-app battery optimization:

Go to Settings
Tap Battery and device care
Tap Battery
Tap Battery optimization
Tap All apps from the dropdown at the top
Find any critical apps (like your launcher or lock screen app) and tap them, then select Don’t optimize

Fix 3: Check Your Always On Display Settings

If your screen looks completely off but the phone is technically “on,” your AOD settings may be masking the real display state.

Go to Settings
Tap Lock screen and AOD
Tap Always On Display
Under When to show, make sure it’s not set to a schedule that covers your current time
If set to Tap to show, a single tap will reveal the AOD — this is not a wake failure

Fix 4: Fix the Proximity Sensor (One UI 6.1 Specific Issue)

Samsung confirmed that the One UI 6.1 update introduced a bug where the proximity sensor misfires at high refresh rates, causing the screen to behave as if it’s in a pocket when it isn’t. If your S23 received the One UI 6.1 update and the display randomly refuses to wake, this is likely the cause.

Samsung’s confirmed temporary fix:

Go to Settings
Tap Display
Tap Motion smoothness
Select Standard (60Hz) instead of Adaptive
Tap Apply

This drops the refresh rate to 60Hz, which stops the sensor misfiring. Samsung has released patches for most regions, so also check for software updates (Fix 5 below).

Fix 5: Install Pending Software Updates

Samsung has released multiple One UI patches specifically addressing display wake and touch response issues. If you’re on an older firmware build, updating is likely to resolve the problem outright.

Go to Settings
Tap Software update
Tap Download and install
If an update is available, tap Install now
Your phone will restart after installation

After updating, re-check whether your wake gestures (Lift to Wake, Double Tap to Wake) are still enabled — updates sometimes reset these settings.

Fix 6: Clear Google App Cache (One UI 6.1 Touchscreen Bug)

Samsung specifically identified the Google app as a trigger for the One UI 6.1 display/touch responsiveness bug. Clearing the app’s data resolves it without needing a full factory reset.

Go to Settings
Tap Apps
Find and tap Google
Tap Storage
Tap Clear cache, then tap Clear data
Restart your phone
Update the Google app via the Play Store to the latest version

Fix 7: Force Restart the Galaxy S23

A frozen system process can lock the display in a sleep state it can’t exit. A force restart clears this without affecting your data.

Method 1 — Power button:

Press and hold the Power button for about 8–10 seconds
When prompted, tap Restart

Method 2 — Force reboot (if screen is completely unresponsive):

Press and hold the Power button and Volume Down button simultaneously for 7 seconds
The Samsung logo will appear and the phone will restart

This resolves stuck power states and any background process that’s locked the display manager.

Fix 8: Boot into Safe Mode to Identify Third-Party App Conflicts

If the display wakes normally in Safe Mode, a third-party app is causing the issue.

Press and hold the Power button
Tap and hold Power off until the Safe Mode prompt appears
Tap Safe mode
Test whether your display wakes normally

If it does, uninstall recently installed apps one by one to identify the culprit — especially battery manager apps, screen lock replacements, or display customization apps.

Fix 9: Factory Reset (Last Resort)

If all software fixes fail and your display still won’t wake consistently, a factory reset will rule out a deep software conflict. Back up your data first — a factory reset erases everything.

Go to Settings
Tap General management
Tap Reset
Tap Factory data reset
Tap Reset device
Enter your PIN or password when prompted
Tap Erase everything

Your Galaxy S23 will reboot to factory settings. Set it up fresh rather than restoring from a backup initially — this verifies whether the issue was caused by a backed-up app or setting.

When to Contact Samsung Support

If the display refuses to wake even after a factory reset, the issue is hardware. The most likely culprits at that point are:

Failed OLED panel — The display itself has died. Samsung replaces these under warranty if the phone shows no signs of physical damage.
Damaged power button flex cable — The button registers presses but the signal doesn’t reach the motherboard.
Faulty proximity sensor — Requires board-level repair or sensor replacement.

Contact Samsung Support:

Phone: 1-800-SAMSUNG (1-800-726-7864)
Samsung Care+ locations: Find a service center at samsung.com/us/mobile/mobile-phones/all-mobile-phones

Samsung’s standard one-year warranty covers display and hardware failures not caused by physical damage or liquid exposure. If your S23 is out of warranty, [INTERNAL LINK: Samsung Galaxy S23 repair cost guide] can help you weigh repair vs. replacement options.

Work through these fixes in order. The vast majority of Galaxy S23 display wake failures are resolved by Fix 1, Fix 2, or Fix 4 — the others exist for edge cases. If you’re on One UI 6.1 and the issue started after an update, go straight to Fix 4 (proximity sensor / Motion Smoothness) and Fix 6 (Google app cache clear).
