Lock Screen

try the below, good luck

1. Check “Show charging information”
This setting can make the screen stay on while charging even if AOD is off.
To turn it off:
1. Open Settings → Battery (or “Battery and device care” → Battery).
2. Tap the ⋮ (three dots) → Settings.
3. Turn off Show charging information (or Show charging status).
2. Check “Keep screen on while charging” (Developer Options)
If Developer Options are enabled, this can override sleep settings.
To turn it off:
1. Go to Settings → Developer options.
2. Scroll down and find Stay awake.
3. Make sure Stay awake is off.
(If you don’t see Developer Options: Settings → About phone → Software information → tap “Build number” seven times.)
3. Review your “Lock Screen → Always On Display” options
Even though you said it’s off, Samsung sometimes flips it to “Show for new notifications.”
To check:
1. Settings → Lock screen → Always On Display.
2. Tap it and ensure it’s set to Off, not “Show for new notifications” or “Show when charging.”
4. Check for third-party apps keeping the screen awake
Some apps (battery monitors, notification managers, smart home apps, etc.) can override the screen timeout.
Try this:
1. Go to Settings → Battery → Background usage limits.
2. See if any apps are “Not optimised” — these can keep the phone awake.
You can also boot into Safe Mode (press and hold Power → touch and hold “Power off” → choose Safe mode) to test.
If the problem stops in Safe Mode, a third-party app is the culprit
5. Double-check “Lift to wake” or “Tap to wake”
Sometimes, while charging, subtle touches or cable movement can trigger these.
To disable:
Settings → Advanced features → Motions and gestures → toggle off Lift to wake and Double tap to wake (just to test).
6. Test with a different charging cable or charger
If it’s an off-brand charger, it might be sending erratic signals that make the phone think you’re interacting with it.
