I received my OP5T today. And after turning on the phone I notice that there is always a small tiny blue dot on the display which is noticeable when I lock/unlock the phone. Will Amazon replace it for me if I file a claim? There is no direct replace button, instead they said an engineer who will come visit my house to check the phone for the particular fault. What should I do in such case when I'm not even available at home? Second of all is is it a dead pixel or something else?
