I had the same issue. It is so widespread I cant believe the thieves refuse to fix it under warranty. I have used smartphones since the days of Windows Mobile on HTC's earliest devices like the TyTN and I have never seen such a rubbish build. The front facing camera was pants too. They asked me to pay £190 to fix it and I refused I have sued LG to court here in the UK and the hearing is in February 2019. I will lose more in a days wages to attend the court date than they are asking for but its a matter of principle. I hate the big boys getting one over us minions.
