I sent my phone in for a camera issue and they changed the screen as well. It took 10days in to total from me dropping it off until it was delivered back at my house.
I'm getting the issue now too.
Mainly the status bar icons that are "burned in". However it looks more like image retention because it goes away after leaving the screen off for a prolonged period of time. I've NEVER had this happen with an IPS display phone, ever.
Thinking about bringing it in for warranty, but a bit hesitant since it's working fine despite this issue, and also after reading the experiences regarding the customer service, though the quality of the service seems to vary widely from place to place.
I didn't have a backup phone until today, so I was unable to send it for repairs. Today, I borrowed a samsung note 4 from a colleague and hope to send it to service service by tomorrow.
I know one thing for sure: LG panels are worst on mobile market. Shame on you HMD!
I received my phone back from repairs yesterday, with new screen.
Problem seems to be solved, but I will wait to see if it deteriorates by time.
BTW, test page for screen retention I use;
This company is really unbelievable! I took a picture now with the website test from above. Two different kinds of burn in after 2 minutes. One in the middle. And the other even stronger, red-tinted one on all sides. Was yours as horrible? Or less? What an unbelievable crap experience Nokia is. I am stunned!
