iphone 13 green display

I faced the green display issue after software update and apple was asking me to pay INR 25,500 for the repairs though there was no external damage or liquid traces to the phone. After several complaints and appointments at apple BKC there was no satisfactory resolution as they said it was a hardware problem not related to software issue. My phone was 4 months out of warranty. A friend of mine suggested to connect my phone to a MacBook and upgrade or downgrade the software and factory reset it a couple of times after getting a backup for the data. It worked on my phone and my display on was back to normal without any repairs done on my phone and without spending a single penny that apple was charging me for no reason. I wasn’t expecting such kind of drawback and customer support from apple as they’re just minting money from the customers to generate profits that is all. I suggest people to think twice before buying apple products in the future. Thank you and I hope this was helpful.
