Fix #1: Check the cable, charger, and wall outlet first

A software update often gets blamed when the real issue is a weak adapter or damaged cable.

1. Try another USB-C cable and Samsung-compatible fast charger.
2. Plug directly into a wall outlet.
3. Avoid testing through a laptop port or low-power hub.

Fix #2: Clean the USB-C port carefully

Lint inside the port can stop charging immediately after an update reboot, making it look like a firmware issue.

1. Turn off the phone.
2. Use a wooden toothpick or soft brush to remove visible debris.
3. Do not use metal tools in the port.

Fix #3: Force restart while the charger is connected

Charging services can hang after a firmware install.

1. Plug in the charger.
2. Press and hold Volume Down and the Side button for around 10 seconds.
3. Check whether the charging icon appears after reboot.

Fix #4: Turn off Fast Charging and test again

Some post-update charging failures affect fast charging negotiation only.

1. Go to Settings > Battery > Charging settings.
2. Turn off Fast charging temporarily.
3. Connect the charger again and see whether normal charging starts.

Fix #5: Charge in Safe Mode

If charging works in Safe Mode, a third-party app may be interfering with USB or battery services.

1. Enter Safe mode from the power menu.
2. Connect the charger and wait a minute.
3. Uninstall recently added battery, cleaner, or automation apps if charging works there.

Fix #6: Wipe the cache partition

Corrupted system cache can break charging behavior after updates.

1. Boot into Recovery Mode.
2. Choose Wipe cache partition.
3. Reboot and test charging again.

Fix #7: Install the next patch or use wireless charging as a temporary workaround

Samsung sometimes ships a quick fix for update-related charging bugs.

1. Open Settings > Software update > Download and install.
2. Install any newer build if available.
3. If wired charging still fails but wireless works, back up your data and book service.
