Did you try video recording? And playback on full volume

it has been long ago iPhone comes with yellowish screen.... the only blueish screen is iPhone 2G, 3G, and 3GS.... 4 have blueish screen but later mostly yellowish and til now...

the only concern is, is it very yellow or not

i think using video capture hissing sound is not so accurate, try heavy load with sound off like play games, play video maybe? run benchmark like geekbench, antutu will likely to push the load to max....

games i found like Marvel Future fight can play in 60fps, not sure any other maybe freeblade or the oz broken kingdom that iphone 7 event introduce but is not easy to test with game since not everyone play game and those game actually need some time to download if you dont have good broadband at home

geekbench or antutu maybe? it may run like 1-5 minutes

No more powerbank

Yup tried what u did. No hissing sound. Guess I'm lucky. Try going to machines centre and see whether they can give u a brand new set

Same as me bro... both of my 7 plus have the hissing sound after I record the video. I also placed tempered glass on both units

Same... mine also light blue after adjusting. Can't really get white

Those with yellowish screen not due to night shift is on right?

nope... it's off

i can hear clearly the sound.

yes me too! but mine is even worst.. haha

Actually those so called hissing already existed. I tried to hear from my iPhone 5 and it is there. It become so obvious in iPhone 7 is due to the 2 power processors that running at high capacity, am I right ?

wah can hear the hiss sound

I think the yellow screen will back turn to normal after few days.

The first time I switch on iPhone 7 plus immediately can see the screen so yellowish, I do nothing and didn't purposely put 6s plus side by side to compare.

But now I think it's normal d, not sure because few days usage and it change automatically or I already get use to yellowish screen and no feeling d? I never adjust the color tone in setting.

when no use the phone,the sound will come out ? or while recoding then the sound come out ?

I don't think there is any problem with that hissing sound. I would rather keep for now than getting a refurbished set from exchanging a new set.

Now I play it on another device, you are right can hear it clear as day

call Apple Support 1800-803-638

well nothing is perfect

you are not alone, same here

like listening to electric shock szzzzzzz sound

Haha.. actually is your eye adapted on it.

This is 7 or 7plus?
Why no people share 7 battery life?
