Rated 5 out of 5 by from This LG Phone Is Awesome!! I absolutely LOVE this phone and LG Products I love how it is easy to use and the way it performs...

Rated 4 out of 5 by from Great "little old lady"phone! I am a 73 year old woman (but I'm not an old lady, mind you!) who is not very good with technology. But when I got my LG k-30 I was really impressed with how easy it was to learn the software. When it died, I upgraded to the K40 and was surprised to learn that it's even simpler to use. The only two recommendations I have: First, please put the comma (,) on the original keyboard so I don't have to go digging for it. Second, in texting, please put the word "draft" in red, so I remember to go back to finish it. I know that these are Cadillac Complaints, but... You asked for my feedback! So please know that I am hooked on LG - but it would be nice to have these two little things. Thank you for making a great product!

Rated 4 out of 5 by from Good little phone The only thing i have negative to say is the keyboard is super slow to learn my typing speed and the fingerprint scanner is finicky. Other than that its a wonderful phone.
