I'm a little confuse now
Wallpaper picker. Is that through my device>display>wallpaper>etc?
To answer your earlier question, yeah it does go to downloads which creates a folder in gallery right? I go there and set as. It's kinda strange because I tried a few others after and some seem like they are hi-res but some are really bad. But when i check the really bad ones the it's always 1920x1200. So I don't know what's going on.
To answer your second post, here's what I do. I go to Google then images and there's a bunch of pictures. I click on one, it zooms in and blacks out the rest of the page screen right? I then hold the screen until it gives options like save image, open image, open in new tab, etc. I click open image and it does open but still doesn't go full screen, it's like the top left only. I'm like what the hell.
I hope my explanation makes more sense this time. But I ended up downloading from PC and putting it on Dropbox then picking it up from the phone. It's a bit of a hassle but got the job done. Thanks for the help btw.
I'm gonna post another problem which is even a bigger hassle, so I'm not to concern about this right now.
