Thank you for your input and the warranty info. The confusion over the 30 days was this sentence in a message from your CS:
'If you recently purchased the device, you may be eligible for a refund or exchange through the retailer within 30 days of purchase ' but re-reading it now this may relate to any retailer warranty. However, at no point did CS indicate that there was actually a 1 year warranty on the device. Does this warranty go with the device, or is it only available to the original purchaser?
As far as I can tell, the issue is only with the boot-up screen. Almost everything else seems absolutely fine. The only other issue I've noticed is that on shutdown, sometimes the battery level indicator is displayed but at other times it isn't.
