Can see the clock if you have a white background?

Hi all,

I have a white background as my lock screen which means i cannot see the clock! Hopefully the iPhone will be smart enough in beta 2 too allow the clock to auto change to black.

Anyone else notice this or have similar problems?

Having this issue as well. It attempts to add a black shadow behind the carrier and time, but on my phone it's still unseeable. Same with the lockscreen.

I don't think it does add shadow! Well, not for me at least.
It's noticable on the lock screen but I think they will sort that out through betas.
Is that what your phone really looks like? With the time and carrier in black?

Here's my phone with a white background.

I can see the carrier and battery etc at the stop due to the drop shadow. But the big clock doesn't have the shadow and just disappears... pain in the ass!

Yes, it is. I just tike the screenshot.
Very bizarre! My guess is it could be a bug! How can it be so different?

PS: Maybe is something to do with the half dark half white wallpaper and the software is not smart enough to determine what colour to use...?

I have no idea but even with the shadow it's impossible to see on mine. Yours looks great. I hope it's a bug as well, could really use the black lettering.

The clock and status bar are meant to adapt to the wallpaper (i.e be either black or white) as demonstrated in one of the developer videos on UI design. If it's not doing that in Beta 1 then expect tweaks in future betas to perfect that.

I'm going to assume for now they're still perfecting the status bar icons and lock screen items adapting to the color of the wallpaper. I say this because I've tried multiple "bright" wallpapers (white or very close to white) and these stay white no matter what. The only wallpaper they've changed to black for is the stock wallpaper that's there when you install iOS 7.

You're probably right that this will work in future betas.

I have just noticed the title is wrong! It was supposed to be "cant see"... not "can see". Oops :D

So; we can't get black text in the icon lettering
rather than white unless we change background? In beta 1 anyways...

What it really needs to do is change Colour like it does on the lock screen.

ive just been playing with backgrounds. if you choose the lighter colour backgrounds from 'stills' on the pre loaded wallpapers then the txt goes black. If you use your own image that is light then it stays white txt.

EDIT...

actually just found one of my own images that puts the home screen and lock screen txt to black txt.

I noticed when you have a notification, it puts a shadow across the entire screen so you can see the clock.

also i think this is why apple used backgrounds that didn't need the black text when they were showing it off at wwdc and on their website

We don't know how this works yet. Who knows, it might be using a very specific, single pixel sample to determine the colour of the background, just to demo the idea. And perhaps some of the ones you've tried are dark in this pixel. Who knows what triggers it at the moment.

One of the developer videos showed this as a general feature, I honestly believe this will improve In future. Submit feedback or a bug if you want though.

The reason this one shows up with white text is because the majority of the picture is dark. Just the top is white (blownout sky). Try with a background that has the majority white.

Figured something out...

*EDIT: BELOW IS INACCURATE. SEE POST 30 http://forums.macrumors.com/showpost.php?p=17463746&postcount=30

I've been playing around trying to figure out exactly where the OS is reading the image to determine whether or not to display white or black text.

I performed these tests on the home screen.

Using a 1136x640 blank canvas I added complete white. The home screen shows black text. Then pixel row by pixel row I added black to the image from the bottom up. Once I reached row 236px the text changed to white.

So far clarification, if you take a 1136x640 canvas and add a black mask with the dimensions 235x640 to the BOTTOM of the image, you will get black text on the home screen.

Here are my examples:

Fist screen shot shows a white background with a black bottom mask of 236x640 (1 pixel too high) and you will see the text is white with shadows:
IMG_0031.PNG

Now with the black bottom mask correctly sized at 235x640 you can see the home screen text is black:
IMG_0032.PNG

Here are the wallpapers I used:
235x1136
ip5_ios7_235.jpg
236x1136
ip5_ios7_236.jpg

**EDIT**
Played around a little more. As it turns out, the actual location of the black mask is irrelevant. You can place it anywhere. The important part is that it is at least 150,400 pixels worth of black or 36.7% :)

In other words, in order to display black text the wallpaper needs to be at least 63.3% white or have 576,640 white pixels. Just a rough estimate. ;)
