Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

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.

Lousy Fingerprint reader

NCBryan01 9/1/2020

I hate this thing. Its slower than my previous K20 and the fingerprint reader is almost useless. Honestly this is the worst phone to carry Ive ever had. Great battery life but the stupid fingerprint reader is becoming too annoying. Ive had the phone less than 6 months. Id rate it a zero if that were an option.

LG never lets me down.

plasticlumberyard 5/15/2020

I love LG products. The cell phone are the best I had a G that T-mobile turned my mic off even though I paid for my phone. Yesterday I got a LG K40 I love it All the features of my G5 and more. 32 GB memory. Awesome screen display. Clear. Many features including surround sound. If you need a good quality phone this is it

Good Phone

JHSS 4/19/2020

LG is my go-to brand and is always my first choice when buying a new phone. Id give it 5 stars except for what I think is a glaring design flaw: you cannot turn off the vibration notification without silencing the entire phone. Its really annoying. Even if you turn the volume off it still vibrates. Definitely a design flaw. And lately whenever I take a screenshot I get a delay of about 10 seconds when the phone freezes this annoying little preview shows up and I get a message that says Cannot save the screenshot even though I have a screenshot. See attached screenshot. I dont know if thats an issue with LG or Android but its annoying. and this is the third time Ive tried to post a review of this phone.

Will not even refresh to latest weather and temp

butch787878 11/11/2019

I bought into Metro by T Mobile last Friday and find that my weather app does not work due to server not available. Say what? Also cannot find a feature that supplies a simple alarm clock settings.

Like the size

Annaphotini 10/28/2019

I had the K10 and the K20 which I totally loved It is still my all time favorite phone. I wasnt impressed with the K30 so I passed on it. So far this phone will meet my needs. Im not really into photos so cant say about the camera. I hope to love this phone as much as I loved my K20 Over all LG makes the best phones I will say that 5.7 inches should not be a small phone it is not The larger phones cause those of us with small hands discomfort.
