Unbearably SlowMe and another family member got this at the same time. It started out fine but within about 2 months both became unbearably slow. Apps lag, opening and closing things takes for ever. It freezes up constantly. I sometimes miss calls because the phone app locks up and doesn't registered my button inputs. I'm pretty tech savy and have done everything I can to speed this thing up but to no avail.

I have requested written instructions more than once. The phone ( understanding that it is discontinued ) is complicated for me and I need help. You were anxious to sell it to me with no back up knowing it was to be discontinued. Bad PR.

Can you take Spectrum mobile off the device...no longer my provider, and use with Verizon?
Asked by: Busymomteach81
Spectrum Mobile doesn't actually own its own cellular network. Instead, it uses Verizon Wireless's cell phone towers to power its mobile service so the LG K40™ | Spectrum Mobile, Model # LMX420QM6 will work with Verizon. Your phone has always been using Verizon's towers....^IFV

I cannot find casting on my wife's k40. Has this feature been removed in the k40?
Asked by: merodach
@ChrisPSM - that's not the issue. The issue is we can not find the option to cast on the phone itself.
