To share my recent experience dealing with GSOD instead.

Woke up one day phone suddenly flickering between green and normal.

Didn't pay much attention, just continued using. It wasn't until the next day, after I unplug the phone the screen went complete Green with white lines on it.

Called Apple support, lodged a case. Was told to send to any of the authorized repair outlet. I choose QCD coz of positive claim experienced b4.

Got a call the next day saying eligible for replacement FOC one off even so my phone was out of warranty (Day 1 iPhone 13PM)

Took them 5 days to sort it out, now back with a new screen that has an additional 6 months warranty, and hopefully nothing happens till iPhone 15 comes out.

To note :

1. Apple support was efficient.
2. Even post warranty phone was accepted thou if you are found to damage the screen urself, RIP ur free replacement. I took care of my phone well, never drop or scratch so I guess lucky enough.
3. No other brand will bother to layan you after warranty ended. So still somewhat impressed with Apple for dealing with the issue and sorting it out FOC.
4. Majority of GSOD / WSOD / YSOD are the Pro / Pro Max models. The technicians says very bloody common.
5. Before sending in your phone, try to call Apple Support 1st if you face any of the screen issue unrelated to human error.

Overall, a positive experience. Hoping never to deal with this hassle again.
