Re: LG G3 Wallpaper problem
If I had to guess based on the limited information provided, you've attempted to use an image that's not the right dimensions. For a scrolling wall paper (a wallpaper that moves as you slide from one home screen to another) you need a 2880 (horizontal) x 2560 (vertical) image, or 1440 x 1280. Basically any image with a ratio of 9 (horizontal) x 8 (vertical). Same thing goes for a non scrolling wall paper, it must be 1440 (horizontal) x 2560 (vertical), or any image with a 9x16 ratio.
If you use an image that does not fit that ratio, the G3 will enlarge the image and and crop out a section that does causing the image to look larger that it is.
