I just recently switched from Samsung Galaxy S6 Edge to an LG G5 because I broke it and the only phone I could afford and found a really great deal, LG G5 already Unlocked barely with a SUPCASE and screen protector which was a great deal for 190$.
The cameras is as good and maybe even a bit better because of the wide screen angle dual camera.
But damn the LG cameras software sucks and pretty much all other apps and other cameras you can download on it sucks...
I miss the Samsung default camera app...
The best apps are the to take photos is the Candy Camera app and a mod or port of the google camera... but still doesn't pleasant to use as Samsung cameras app.
Candy Camera : For filter and photo editor (It's the best)
I just posted the Port/Mod in the LG G5 section.
