Wallpaper automatically blurring after a while Since a few days the wallpaper of my Samsung Galaxy S7 is getting blurred after i use it for a while (10 minutes to an hour).

i just select a picture, tried 5 different ones, (even the stock wallpaper) and after selecting the wallpaper it looks perfect and as it is supposed to be.

then after not using the phone for a few minutes and i unlock it again or after a reboot the wallpaper looks totally blurry.

i haven't installed any apps the past days before this started happening. anyone got an idea what is wrong?

extra info:


using the default Samsung Launcher. tried Nova launcher same problem.
used multiple apps to set the wallpaper (using settings of the launcher and using Google wallpapers app both same effect)
I personally don't have this issue, but this is how I solved a friend's phone with this problem:


On your phone, go to Google Play and install the app Muzei
Once installed, tap the open button in the Google Play app. You will be greeted with a splash page with a button that says "activate". Tap the button, and then click set wallpaper at the bottom of the screen.
Now you will see a new screen telling you to double-tap your wallpaper to see it in detail. There will also be an icon near the middle of the screen. Tap the icon.
At the bottom-right corner of the screen, tap the three dots, and then in the new menu tap customize.
Drag left to reveal an option reading "my photos". Tap it.
After tapping it, a small settings icon appears under it. Tap it.
At the bottom of the screen, tap the "+" button under the text reading "Choose specific photos instead".
It will then open the documents app. to get to your photos you can tap the button at the top-left corner of the screen, revealing a new menu. In this menu, tap gallery. Now you can choose one of your photos (or multiple photos).
After choosing a photo, tap the back button at the top-left corner of the screen. You should see the screen you saw in step 5.
Now tap the text at the top of the screen reading "Sources", and in the new menu that appears tap "advanced".
You will now see sliders labeled, "blur", "dim", and "grey". For a completely clear image, drag all of them completely to the left, but you can set these however you want. You should uncheck "apply blur on lockscreen" and you may also want to uncheck "New Wallpaper Notifications".
Tap the check mark at the top-left corner of the screen. Now you can close the app and go home to see your clear image.


With this method, you are also able to adjust the brightness of the image by opening the app and following steps 4 and 10-12 in that order. To change the image later open the app and follow steps 4-9 and 12 in that order.

If there are any more issues, I am very happy to help.
