Lg g4 wont wake up unless I push power buttons on back

I just purchased a used VERIZON LG G4 and am using it on straight talk service. Everything seems to work fine when using it but the knock on feature and the feature where u out pull down the see the clock and any notifications while the screen is locked does not work. It will lock if I double tap on a blank space on background while it's awake. Also my LED notification light works erratically and my screen does not wake if I get a text or any other notifications . Please let me know what's normal and what's not and if there is anything I need to know. Thanks in advance for any help or advice ☺

That's most definitely NOT a normal behaviour.
My advice is for you to take the phone to repair. I don't know how feasible that'll be since you bought it used, but you need repair. If you have the box of the phone, check the serial number. If it starts with 509 or lower (508,507, etc) it's likely one of the defective units.
My G4 has been with LG for repair for over 2 weeks because the motherboard died but before it died, it showcased behaviour similar to what you're describing. So you may want to have that in mind.

This happened to me and I couldn't figure it out, but it somehow fixed itself after a couple of weeks. Good luck!

I'm with AT&T and we never had the pull down feature, but my tap on has been tapped out for a couple weeks now. Not sure if it's a Marshmallow thing.

I don't think the screen is supposed to wake when a text or other notification arrives. That's the purpose of the blinky light.
