S21 Galaxy 5G keeps restarting when charging

[VMPindoria]

My Samsung Galaxy S21 keeps restarting when plugged in for charge via USB C. However, phone charges fine when docked wirelessly. 

Is this an issue with the port or a software issue?

Please check your phone's software is updated as well as your apps.

It might be worth using a 🔦 to **bleep** inside the charging port to see if there is any debris lodged in there @VMPindoria 

Also try another Samsung Charging Brick and official data cord if you can.

If this continues then it's always worth clearing the phone's System Partition Section Cache Files and try Safe Mode. 

• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too. 
• Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 

Also please do send your feedback via your Samsung Members App so this goes directly to the relevant Samsung Department. 

If the above ^  fails to resolve the issue then yes let a Samsung Service Centre have hands on.

If I can be of any further help then please don't hesitate. Take care.  😎
