What people are saying

Rated 1 out of 5 by from DEMON POSSESSED I got my K40 a year ago as an upgrade from my LG K8+. I always get an LG phone. I have always had very good LG phones but I sure did get a rotten one this time. I didn't have it 2 months and it got very slow and I was getting pop ups that the System wasn't working. I cannot count now how many times I have had it to the store and talked to customer service. About 3 months ago, it started making its own phone calls and I wasn't even touching it at the time. Then I would get phone calls and it wouldn't let me answer them. I have always had trouble keeping my 4G on and we have reset the specs probably 7 times in the last year. I have even backed everything up and reset it back to factory 2 times. This phone has been a joke and the worst I have ever had. Thankfully I am almost ready for an upgrade. I will more thank likely go with an LG but be sure, I will take it back if it is like this one.

Rated 3 out of 5 by from Mirror letdown With all this phone has to offer if you don't have wifi at home you cant mirror your screen like lesser devises can. I have a UHD Lg Tv and I can't for the life of me mirror to this or other tv's. A friend had a cheaper Acetel phone clicked share like the lg the tv switched over to mirror his phone with a tap. I downloaded may apps and none just took over the TV and mirrored. Direct devise to devise. It boggs when memory is over 90% . also UI constantly cuts out. Keyboard at time just dissapears then pops up. But for the dollar for dollar I am glad the price was lowered. But control other divices connected It was a letdown

Rated 1 out of 5 by from I got my upgrade lgk40 and was stuck with a lemon. No one wants to help me. Us cellular says ti contact lg manufacturers and lg says to contact us cellular. I used my upgrade and got stuck. No one will help me and I'm tired of fighting a losing battle.
