I think your best option @ACritchlow is to let a Samsung Service Centre have hands on to assess it.
The phone has a 24 month Wanufacturing Warranty.
This however does not cover free repairs for issues caused by an accidental drop / bump or water damage.
If I can be of any further help then please don't hesitate. Take care. 😎
