Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

I bought the LG K40 from metro pcs. I have been super satisfied with its performance. It was a great value for the cost and has really good features. I love the google operating system. It takes good pictures and has a decent amount of storage.

Nu2Nix 1/26/2021

It was the phone that came with the phone plan but it was a really good phone. I never had any issues with it and really no complaints. Good camera and it lasts forever. Only reason I got another one was because I ran out of memory but I take a ton of pictures. It was such a good phone I got it 2 times in a row.

I bought this phone December is 2019. So far its working out well for me. I am a Samsung Galaxy Girl but my sales person convinced me to give LG a try. I am pleased so far. The phone has some pretty neat features the camera quality is awesome. I love taking pictures so that is one if the features that had to be on point for me to consider this phone. The operating processor is greatAndroid 9. Pages turn quickly just waiting for the latest upgrade. Overall Im loving this LG phone.

Over all LG product are ok.

G T J 1/7/2021

When purchase this product two days later had problems with the video screen or play back turned green. With in 5 days all text messages would duplicate and you couldnt clear cache. With assistance from customer services cache and factory reboot was attempted and failed. By second week Wi-Fi connection issue and blurred images. By the end of the month even while on the phone I was disconnected and received a message saying I could only use wifi calling. I have unlimited data plan there were a lot of issues with this phone that did not get resolved. But due to the fact I mostly use the phone for reading. When I do watch a video the images starts out blurry then it will clear as time goes on.

K40

Lilmama73 12/27/2020

I have to say that Im happy with my k40 do I love it more than my k30? Not for real The k30 is a little bigger as far as the screen it also allows you to store games on your SD card. The k40 does not. But overall its still a decent phone to have

So much Memory

Nu2 N 12/26/2020

I was skeptical when my boyfriend brought it home because we got new phones to get rid of an LG that was a bit slow and had no space in it K40. The amount of stuff I have on this phone is ridiculous and Ive barely made a dent in my storage. Plus its way faster and had a bigger screen. And Ive never seen a better camera on a phone before. Extremely happy with our purchase and I highly recommend one

This could be the best phone but isnt

MelvinG24 12/20/2020

I just had 6 months with the phone just before I ended up buying a new one. - Good things about this phone: Is cheap cool features great display and battery. - Bad things about this phone: Volume buttons stop working after a few months. Very very very bad performance super slow. The phone was so slow that it took from 2min to 5min to open the camera and take a single pic. It was so slow that every time I was typing it types more characters because the phone ran so slow that it didnt catch when I release the key. The phone unlock was very frustrating because it was so slow that every time I pressed the power button to light up the display it took so long that I always ended up thinking that I havent press it but when I pressed it again it was just to see the display flash and go back to dark.

Shawnay 12/17/2020

I have previously purchased other name brand phones but now I will only purchase LG phones. I like that it is not a learning curve and its ease of use across the entire line.

Personal..Everything

Eiuol 12/15/2020

I have had this phone now since April 2020 an it is still alive and well running. Even though the other day an accident happened and my screen cracked the phone keeps on going. Ii I fill up the phone with so much music and pitcures of my cats and the phone keeps all my files nice and secure. The internal files are excellent except for the likes of Facebook i am not into social media. And very helpful with aspects of every day life.

Good phone for price

Wolf 11/6/2020

I had it now for a year and in general Im ok with it. The camera is annoying I missed many great shots because the stupid thing simply wont fire even in decent lighting conditions. But considering the price its a useable phone.

Great little old ladyphone

Michaeleen 6/12/2020

I am a 73 year old woman but Im 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 its even simpler to use. The only two recommendations I have: First please put the comma on the original keyboard so I dont 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

AquaRose28 5/26/2020

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.
