Why is my LG Stylo2 messaging app very slow

[Mark Marcarian]

Have an LG Stylo 2 and for the past few weeks when I go to send a message there's a five second delay. Never had problems. I keep the phone clean and hard boot. Nothing works. It's an Android version 7.0, software version LS775ZVB. Kernal 3.10.39 it's not rooted. Don't know enough to do that....

Can anyone help?
