Hi,
If it only arrived yesterday it appears that it is new, is this correct?
And as it is a newly released model also either way it should still be covered by the ''manufacturer’s warranty'', which may be up to 2 years depending on your location.
It is better that you get the problem fixed under warranty than risk voiding the warranty by opening the device to try and solve the problem yourself as you may need the warranty for whatever reason later on. That’s what warranties are for
If you want to do this then here’s the [guide|126223] guide, which may help. It is not a repair guide but shows how to access the various components in the device
