Fix #1: Force restart the Galaxy S25

A forced reboot often brings the screen back if the system is stuck but the phone is still powered on.

1. Press and hold Volume Down and the Power button for up to 20 seconds.
2. Release the buttons when the Samsung logo appears.
3. Let the phone boot fully and watch for the screen to return.

Fix #2: Charge the phone for at least 30 minutes

Some update-related black screen cases are really deep battery drain plus a frozen display.

1. Connect the original charger and cable.
2. Leave the phone charging for 30 minutes.
3. Try another force restart while it is still plugged in.

Fix #3: Remove accessories and cases, then cool the phone down

If the device overheated during or after the update, the display may stay dark until temperatures normalize.

1. Remove any thick case or magnetic accessory.
2. Disconnect USB-C accessories and wireless chargers.
3. Let the phone cool for 10 to 15 minutes before trying again.

Fix #4: Boot into Recovery Mode and wipe cache partition

A bad system cache can keep the phone stuck on a blank display after a firmware update.

1. Turn the Galaxy S25 off completely.
2. Boot into Recovery Mode.
3. Select Wipe cache partition, then reboot the phone.

Fix #5: Try Safe Mode if the screen comes back briefly

This helps confirm whether a third-party app is crashing the display or launcher after the update.

1. Press and hold the Power button.
2. Touch and hold Power off, then tap Safe mode.
3. Use the phone for a few minutes and remove suspicious apps if the issue stops.

Fix #6: Install the next patch if one is available

Samsung often pushes a follow-up build when a display bug appears after a major update.

1. Open Settings > Software update.
2. Install any newer build available.
3. Restart the phone after the update finishes.

Fix #7: Factory reset or book hardware service

If the Galaxy S25 still has a black screen, the update may have exposed a deeper firmware or panel issue.

1. Back up the phone if you can still access recovery or Samsung Smart Switch.
2. Use recovery mode to factory reset only as a last resort.
3. If the display stays black, contact Samsung for hardware diagnostics.
