I purchased this about 4 months ago and I have a 900m scroll in size 9 Calibri font on why this phone is THE WORST PHONE TO EVER EXIST.
So it comes with 16 gb of storage whick sounds fine until you realize that 10 gb are taken from the system and then 5gb are apps that are pre-installed so you can't delete them. There's basically as up to you having less than a gigabyte left to download your own apps, pictures, or music.
Now the obvious answer is by an SD card, which I did, except unlike older LG phones this one doesn't allow you to move any apps over to SD card unless it's an APK so basically only files can be moved, it is also extremely slow after about a month and the battery life after 4 months of me owning it to which I charge to 100 and then start charging again when I get to 15% and I never overcharged so the battery life is just bad. Don't buy this phone unless you're not planning on downloading anything on it or ever using it, because if you never take it out of the box it works completely fine which is why I'm giving it one star and not zero.
