Method 1: Force restart the phone

A black screen right after an update is often just a hard system crash.

1. Press and hold Volume Down and Side for about 20 seconds.
2. Wait for the Samsung logo to appear.
3. If the phone boots up, monitor it for repeated crashes.

Method 2: Charge the phone for at least 30 minutes

The battery may have drained during the update, leaving the device unable to boot visibly.

1. Connect the phone to a working charger and cable.
2. Leave it charging for at least 30 minutes.
3. Try another force restart afterward.

Method 3: Remove accessories and let the phone cool down

Overheating or a bad USB-C accessory can stop the phone from starting normally after an update.

1. Disconnect chargers, docks, and USB-C accessories.
2. Remove the case if the phone is very warm.
3. Let it cool for several minutes before trying again.

Method 4: Check whether the phone is on but the display is not responding

Sometimes the system is running while the screen stays black.

1. Call the phone from another device.
2. Listen for vibration, ringtone, or notification sounds.
3. If it responds, the display pipeline may be stuck rather than the entire phone.

Method 5: Boot into Recovery Mode and wipe the cache partition

A corrupted system cache can prevent normal startup after a firmware install.

1. Power off the phone if possible.
2. Boot into Recovery Mode using Volume Up and Side.
3. Choose Wipe cache partition, then Reboot system now.

Method 6: Try Safe Mode if the screen comes back briefly

If the black screen only appears after startup, an app may be crashing the system UI.

1. When the phone is on, open the power menu.
2. Touch and hold Power off, then tap Safe mode.
3. Remove recently updated apps if the problem disappears in Safe Mode.

Method 7: Reinstall the update with Smart Switch or Recovery if needed

A damaged install may require a fresh system restore.

1. Use Samsung Smart Switch on a computer if the phone is detected.
2. If Recovery Mode works, use the update or repair option available for your setup.
3. Back up your data first whenever possible.

Method 8: Get service if the screen stays black on every boot attempt

If the phone never shows an image even while detected by a computer, hardware could be involved.

1. Try connecting the phone to a computer and see whether it is recognized.
2. If it is recognized but the screen never lights up, contact Samsung support.
3. Explain that the black screen started after the update.
