Why does the top of an iPhone wallpaper blur during setup on iOS 17 and later?

On iPhones running iOS 17 and later, moving a wallpaper during the setup process causes the top area to be blurred with solid black or white. This is a known iOS behavior. The workaround is to use a screen-sized screenshot or an extra-tall cropped image and swipe up during setup rather than moving the wallpaper freely.

Why is a screenshot more reliable than a Photos-cropped image when setting a wallpaper on iOS 18.2?

Some devices running iOS 18.2 have a bug where edits made in the Photos app — such as cropping — are not reflected when the image is set as a wallpaper. Screenshots bypass this issue because they are saved as new image files with no edit history. For this reason, using a screenshot is more reliable than cropping an existing image in Photos.

What changed in iOS 18.2 regarding wallpaper top blur?

iOS 18.2 restored the ability to cancel wallpaper top blur by swiping up with a screen-sized image on many devices — a feature that had not worked reliably on many devices in iOS 17.1 through 18.1. However, iOS 18.2 also introduced new bugs: auto-fill stopped working for some wallpapers, and some devices developed a bug where Photos edits were not applied to wallpapers. iOS 18.2 went through four specification changes (RC-1, RC, RC2, and the official release) in rapid succession, leaving various bugs unresolved.

Why does exporting an image through the Notes app help avoid wallpaper blur?

Saving an image to Notes and then re-exporting it to Photos creates a new image file that no longer retains the original composition data. This strips the metadata that causes iOS to auto-position the wallpaper in ways that trigger the top blur. Any round-trip export — via AirDrop, a third-party photo editor, or any other method — achieves the same result. The Notes app is the most accessible free option for users with a single iPhone.

What does Home Screen Tinted Mode do on iOS 18?

Tinted Mode, introduced in iOS 18, applies a unified color tint to all icons and widgets on the Home Screen. When enabled, the Home Screen automatically switches to Dark Mode and all elements share the same color tone. The tint is derived from the overall wallpaper color by default, but can be adjusted manually.

How do I change the tint color in Tinted Mode on iOS 18?

Two methods are available. The Pick option lets you tap a specific point on the wallpaper to sample its color for the icons. The Manual option provides two sliders — the top controls hue and the bottom controls saturation — for fully custom color adjustment. Tapping the Tinted icon again, or switching to a different customization mode, resets both adjustments back to the automatic wallpaper-derived color.

Why does the wallpaper darken when Tinted Mode is enabled?

Tinted Mode forces the Home Screen into Dark Mode, which causes the wallpaper to darken automatically. This is the same darkening behavior as other Dark Mode customization options in iOS 18. To counteract this, tap the brightness button (①) in the Customize panel to brighten the background independently.

Is Home Screen Tinted Mode available on all iPhones running iOS 18?

Tinted Mode was introduced in iOS 18, but may not function correctly on all models or minor versions of iOS 18. If the feature does not appear or does not apply color correctly, this may be a model or version compatibility issue.

What Always On Display options are available on iOS 16.2 through 18?

Go to Settings > Display & Brightness > Always On Display. When Always On Display is enabled, two toggles appear: Show Wallpaper and Show Notifications. Their combinations produce five display states: (1) Clock, wallpaper, and notifications — all on. (2) Clock and wallpaper only — notifications off. (3) Clock and notifications only — wallpaper off. (4) Clock only — Always On Display on, but both toggles off. (5) Nothing shown — Always On Display off.

Why doesn't turning off only Show Wallpaper work for wake-animation wallpapers on iOS 16.2–18?

Wallpapers on Mysterious iPhone Wallpaper that appear to move at the moment of wake rely on the transition from a completely dark screen to the active Lock Screen. Turning off Show Wallpaper alone is not sufficient — the screen still shows the clock and a dimmed state, which prevents the animation effect from triggering. Always On Display must be turned off completely (option ⑤) for these wallpapers to work as intended.

Which iPhone models support Always On Display on iOS 16.2–18?

Always On Display is available on iPhone models with an Always On Display panel. See Apple's iPhone User Guide for the full list of supported models: https://support.apple.com/ja-jp/guide/iphone/aside/iph84d983c01/

How do the Always On Display options differ between iOS 16.2–18 and iOS 26?

The core options — Show Wallpaper and Show Notifications — are the same across iOS 16.2 through 26. However, on iOS 26, an additional Blur Wallpaper Photo option was added, and the setting can be found in a slightly different location. The critical note about wake-animation wallpapers requiring Always On Display to be fully off applies to both versions. See https://tt-t.com/heyeased/always-on-display-map.html for the iOS 26 details.

iOS 12のホーム画面の変更点

iPhone Xの表示位置の変更
iOS 11
視差効果用等倍壁紙サイズ：1301×2820ピクセル
表示位置：左から86.5ピクセル・上から59.5ピクセル
iOS 12
視差効果用等倍壁紙サイズ：iOS 11と同じ
表示位置：左から87ピクセル・上から60ピクセル

壁紙の一部だけが暗くなることがある
iOSはコントラストや明るさなどを判定して壁紙を暗くしたり文字の色を変えたりします。iOS 12では壁紙が暗くならない場合でも、白文字になると白や淡い色だけが暗くなります。

ドックの色が若干変更された
壁紙が暗くされる場合のドックの色が微妙に変わりました。機種や色によってまちまちです。Xでは総じて明るく、その他のiPhoneでは暗くなるようです。

「透明度を下げる」のルール変更
iOS 11
ドックとフォルダの色：背景を問わず一定のグレー
設定方法：設定 > 一般 > アクセシビリティ > コントラストを上げる > 透明度を下げる
iOS 12
ドックとフォルダの色：基本的に背景を暗くして彩度を下げた1色。ただし壁紙が一定以下の明るさだと、通常モード同様に背景より明るい1色。
設定方法：設定 > 一般 > アクセシビリティ > 透明度を下げる

アイコンバッジ
アイコンバッジの赤がやや明るくなりました。

設定できないサイズ
iOS 11同様に一定の範囲の極小サイズの壁紙は設定できません。ただしそのサイズがiOS 11とは違います。

デフォルトで普通に使っていたら気づかない変更ばかりですが、当サイトの壁紙にはそれなりに影響があります。

Changes in iOS 12 Home Screen

Changing the display position of iPhone X
iOS 11
Uniform wallpaper size of Parallax Effect: 1301 × 2820 pixels
Display position: 86.5 pixels from the left · 59.5 pixels from the top
iOS 12
Wallpaper Size: same as iOS 11
Display position: 87 pixels from the left · 60 pixels from the top

Only a part of the wallpaper may become dark
iOS judges contrast, brightness, etc. to make the wallpaper darker or change the color of the letter. In iOS 12, even if the wallpaper does not get dark, only white or pale colors will become darker when the letters turn white.

The color of the Dock has been slightly changed
The color of the Dock has been changed slightly when the wallpaper is darkened. It varies depending on model and color. It looks brighter in X and darker in other iPhones.

Rule change of Reduce Transparency
iOS 11
Dock and folder color: constant gray regardless of the background
Setting menu: Settings > General > Accessibility > Increase Contrast > Reduce Transparency
iOS 12
Dock and folder color: Basically, it is darker than the background, one color with low saturation. However, if the wallpaper is less than a certain brightness, it is one color brighter than the background like the normal mode.
Setting menu: Settings > General > Accessibility > Reduce Transparency

Icon Badge
Red of the icon badge got a little brighter.

Sizes that cannot be set
As with iOS 11, wallpaper of a very small size within a certain range can not be set. However, its size is different from iOS 11.

Although it is only changes that you do not notice if you use it normally by default, the wallpapers of this site are affected to some extent.
