What people are saying

Rated 2 out of 5 by from Phone locks up constantly and loses internet connectivity. Have to reboot often to make it reconnect to internet using cellular data. Usually try to turn it off when it locks up, but it usually just hangs for quite awhile before it will turn off.

Rated 5 out of 5 by from great phone easy to use I really like the fingerprint unlock. This is my third LG phone no problems with the old one just an upgrade

Rated 1 out of 5 by from Junk Bought this phone because US Cellular was out of Motorolas at the same price. Pure JUNK! Outbound mic gets cut off constantly during calls because keypad randomly come on during calls along with various other programs. Today it started saying I had plugged in to the audio jack preventing me from using the phone to make outbound calls or even listen to Pandora. Even after a reset it still showed it. Now the screen keeps going unresponsive. After not even two months of use I'd of rather purchased and trained a fleet carrier pigeons to do my long distance communication tasks they'd probably last longer even with the brutal Iowa winters.

Is the LG k 8x compatible with contactless payment

Asked by: Amanda146
Regrettably, the LG K8X | U.S. Cellular, Model # LMK300UM does not support near-field communication (NFC) so you cannot make contactless payments with Google Pay. Google Pay works on any NFC-F-enabled Android device running Lollipop 5.0 or higher for in-store purchases. However, even though it is not an NFC-enabled phone, you might be able to make Google Pay purchases in merchant mobile apps...^IFV
