Excellent budget phoneAs a person that goes through a lot of phones because of various reasons I have had a lot of budget phones that really seemed ...well budget. The LG K400 feels and acts like an upper tier phone. Also I play alot of games and the graphics and speed are exceptional in this phone. Massive expandable storage etc. are not things I have come to expect in a budget phone . I had a k40 ( expression plus 2) and loved it so I decided to try the 3 and so far it has not let me down and is quickly becoming my favorite budget LG . Keep up the good work LG those of us that buy budget phones are glad at least one company values the consumer that makes an average living and provides us with a quality product

Major Flaw For MeI bought this phone on 10/08/20 to replace my 3 year old LG Phoenix 3 which was having issues. This phone has a major flaw. It does not notify me when I get a text message, email, missed call, etc. No sound, no Icon, no blink LED when I receive the above mentioned things. I have to check the phone constantly to see if I have received anything by opening the apps...frustrating! The LG Harmony 4 has the same problem. These two phones are the same just used by different carriers. The reviews on the Harmony say there is not a fix for this problem. I never had a problem with my Phoenix except for poor carrier signal and it was a much cheaper phone! I bought this phone to get a better signal and it does. The rest of the features and tons of apps, I don't need...just want notifications. Is there a fix for this LG?

Does this phone not notify you of a missed call, text or etc
Asked by: ken knies
If there is a missed call, the status bar at the top of the screen on the LG Xpression® Plus 3 | AT&T, Model # LMK400AKR displays an icon of a black phone with a right angled arrow pointing to the left.To view missed call details, drag the status bar downwards. You can also tap the green phone icon on the home screen and tap Call logs...^IFV
