My iPhone 6 screen is making a clicking sound under light pressure towards the bottom of the screen.

did u managed to change it with a new phone?

bigger thread about same issue here: loose screen on the iPhone 6?

I bought iphone 6 yesterday (1 Mar 2015). I noticed the same issue. Bottom right of the phone screen panel is a bit loose. There is a visible movement in the panel when you press it gently. I am based in UAE and I purchased this phone from Du. I hope they replace the phone rather than servicing it. Du people refused to comment or entertain my complaint on the phone and advised me to go to their store. I can see there are many threads on similar issue and people have complained recurring problem on serviced units.

What was the name of the retailer where you purchased the device? 'Du'? I'm not seeing that they are an authorized retailer of iPhones in UAE.

Yes I have the same issue in South Africa.... Logged a ticket for a technical session at the iStore. Hopefully they'll replace.

Is it just me or are there many issues on the iPhone 6?!?

Hey dude, I'm also in SA and I bought my iPhone 6 from mtn and it gave me the same problem, I sent it in for repairs and they said that there is nothing wrong with it. Did the iStore replace your phone?
