I was looking for some opinions. I have Series 3 Apple Watch and was in Dubai. At one point, the screen began to refuse presses, and then began to detect ghost activations. It then had episodes that lasted hours where the screen didn't show anything at all – this despite the fact that the rest of the clock was working to see that alerts still caused vibrations and that my iPhone could connect to it.
I returned to the UK and booked an hour at the Apple Store Genius. The day I ordered the deal saw the customer service technique clock and saw that it didn't work. At some point while waiting for the agreement a few days later, the watch screen began to work again. Just like back to normal. I took it to the deal anyway, and they ran the diagnosis on the spot that didn't identify a problem.
