Chosen Solution

I tried so much that it gets annoying. My lock screen wallpaper can’t change its pic from the older one. When I tried to change it at the display settings, it says that my settings had stopped; something like that. Please answer this asap. Thank you.

Is it resolved? If not, some solutions are: Delete the launchers data and get rid of any bug/glitch that’s stopping that. But that would mean your whole home screen/wallpaper will be changed back to how it was from the beginning. Turn it off and back on. Make sure fastboot isn’t on in the battery manager settings. Q: Can you change it to the original wallpapers? Q: Can you change it to screenshots from your phone? Q: Can you change it to a photo you’ve taken IN HIGHEST resolution? Q: How do you change your wallpaper, and what Lenovo phone do you have?

because you got to google it :(

Y cannot I change my wallpaper?

Please supply instructions for how to change this phones wallpaper? LG K51.
