iPhone XR Screen Flickering

Hey Community,

My iPhone XR 64GB Black has been acting up, sometimes the screen would just go pink and it would reset or it would just reset in general, however this time, I was switching to the app 'TikTok' and the screen started going yellow and bars appeared on the screen.

It started getting darker and darker until it was black and white. I let the phone die out, it reset and now the screen is actually working and I can use my phone, however the bars are just flickering on my screen now.

I contacted the Sky Support Team (Apple Support was closed), (the phone is on contract from Sky)

They have given me a phone number to call from their repairing partner, however I was wondering if anyone else had found a good and easy solution aside from repair. My phone is about 4 months old, things like this really shouldn't happen especially for a £749+ phone from Apple.

Hopefully I can get an answer!
