Yes I know I shouldn't have done where you put a lot of alcohol on a paper towel and drench it on the iphone. I did that a while back though. Someone said doing that won't damage an iphone screen... that has to be false right? They said alcohol can't get in the iphone.
After a lot of alcohol on the iphone, is when the green vertical line showed up. The bigger issue now though is the flashing green screen.
It seems to me that you are still haunted by alcohol.
Assuming you were correct. Alcohol caused the green strip on your phone.
Then what are you gonna do about it?
I supposed you have been using the stripped iphone since Nov 2023.
If you are fine with it for several months, probably you are fine with it for a more couple months until purchasing a new phone.
My story:
I purchased a second hand iphone 11prm from a small store in my neighborhood. The store owner set a 3 month warranty for it.
One month later, I got the green strip.
I took the phone back to the store for a check. Store owner said that the screen was defective due to user error (cumulative physical impact or something). At first, he offered a share cost plan (50/50) to replace the screen with another original screen (salvaged from iPhone 11prm), but after some exchanges, we settled down to the solution that he would replace it with a new OEM screen for free, just for this time, as the iPhone screen is not covered in his warranty. (He forgot to tell me that at purchase, so the cost was on him this time)
He also talked to me that even if I had purchased the iPhone brand new, sealed in box from an authorized dealer, Apple would still have refused to fix the screen issue, deeming it as "user errors". (This may only be applied to VN, not for other countries)
I also asked him if I had to bring the phone to him again for screen defective, how much he would charge me to replace the OEM screen. The answer was 50$.
For you, if you want to repair your phone, I suggest you look for a repair shop in the neighborhood where you are now, rather than waiting until you are back to the US. Probably you can find a better deal.
Or better yet, find another refurbished iphone 13mini and save yourself the cost of repairing. (Second hand 13 mini are offered by the shops here in HCMC at the price 350$, 6-month warranty, screen is exclusive)
