Tnxs for your reply.
The 1 year warranty is called: Apple One-Year Limited Warranty, but I was not referring to that in the scope of my question. I am referring to the seller warranty from month n.13 to month n.24 (Consumer Laws).
I was not even referring to Brexit.
You could see my question as "Purchasing an iPhone in EU country A and making the claim in EU country B".
There are very different answers and experiences on the web and I would like to have a consistent information before deciding where to buy.
There are customers who have been told by an Apple Store in country B to make the claim in country A, and other customer who had their iPhone repaired in country B without any issue at all.
I am referring to the Apple Store as the seller, who need to provide warranty for 2 years and not as Apple, who provide the Apple One-Year Limited Warranty.
