Do you want to change the wallpaper on the Home and Lock screens automatically? You may also want to change them every time you lock the phone. If yes, Wallpaper Auto Changer is the app you are looking for.

Auto Changer Features:

Separate Images for Home and Lock Screens:
It means you can apply wedding photos on one screen and nature photos on the other screen. You can also tweak settings for individual screens. For example, changing the background color and scale type of the image.

Add Multiple Folders for the Slideshow:
Add multiple folders for both screens. You can apply, change, or delete them whenever you want.

Change Wallpaper Every time You Unlock the Phone:
Yes, just press the power button and the wallpaper will be changed. You can set this feature on both the screens or individual screens.

Set a Frequency Interval for the Slideshow:
If you don't want to change the image on every phone unlock, you can also set a time interval for the slideshow. For example, you can change the home screen wallpaper every 10 minutes. Select a folder and after a certain time, the images are changed automatically. Currently, supported intervals are 15s, 30s, 45s, 1m, 5m, 10m, 15m, 30m, 45m, 1h, 4h, 12h, and 24h.

Pause the Auto Changer:
You can also pause the auto changer when you don't use your phone. For example, while sleeping. During this time, wallpapers are not changed and you can save the phone battery.

Brightness Dimmer:
This is a different feature. It allows you to dim the screen brightness below the system level. This is useful when you use your phone at night. It protects your eyes. You can change the dimmer percentage and the color. If you want to turn it off, just shake the phone 5 times. You can adjust this in the settings. This feature requires Accessibility permission.

ACCESSIBILITY PERMISSION USAGE:
To make the 'Brightness Dimmer' feature work, we need ACCESSIBILITY permission. It helps us to dim the screen. We do it by adding the overlay on the screen. Without the permission, the dimmer doesn't work properly.
We DO NOT collect any personal or sensitive data and we NEVER observe your actions. This is to just for adding the overlay on the screen.

Apart from this, the app supports light and dark themes.
