I have an iPhone 6 with problems on the screen, buy it in late December and from new brightness varies throughout the day, many will say it disables the auto brightness, and it always amazed ALWAYS this off. Call Apple and they said it was a software problem, but I get the update, formatie, restore, set up as a new iPhone, and the problem continued. I contacted again and was told there was another to take it to a service center (live in Mexico, there are no Apple Store) which is still my surprise upon arriving to the service center, the manager tells me I have mail Apple, with my serial number indicating an immediate change. Reported fault: display lighting. The fact is that I get the new iPhone from its case and poof! Same problem, configuring the iPhone like new again see the change in brightness. It is as if 100% will jump to 80%. What do I do? Again he scored to Apple? I give up? I ask Unlike FOR 6 Plus? Any advice?
