Does any else have an LG Stylo 4 that pulses after being disconnected from charger?

[Android Central Question]

My LG Stylo 4 starts to pulse (screen dims, beeping noise, and light blinks) constantly after I take off the charger. It normal suppose to do this when I first plug in the charger. So the phone is basically acting like im plugging and unplugging the phone constantly. Ive tried seing if there is a way to turn this charging notification off but no good.

Welcome to Android Central! Use a can of compressed air to blow out the charging port, and a Q-tip dipped in rubbing alcohol to clean the contacts.

Does the port otherwise work normally? Does it charge appropriate, and when you connect the phone to a PC via USB, does it transfer data successfully?
