iPhone 13 Pro screen showing white colour display only

exactly....same issue here. phone just randomly started going all white without me doing anything. did all the force restart procedures but it dint help. phone works cos i can pick and make calls with my apple watch without activating cellular on watch. Touch works too as i was able to unlock phone using password by muscle memory. Apple support wasnt a help at all. Why should I be paying 35k in Indian Rupees to repair a damage I did not contribute to. If apple doesnt take any responsibility for this I am selling my apple products and never investing in their products ever. Apple is going carbon neutral by making their customers old devices useless through updates.

Try and force restart the iPhone to see if the issue is persisting

1. Press and quickly release the volume up button.
2. Press and quickly release the volume down button.
3. Press and hold the side button.
4. When the Apple logo appears, release the side button.

If this is not working, there is an hardware issue going on, please Contact - Official Apple Support to set up hardware service

Did you try to force restart? A lot of users are facing these issues and it's apparently an hardware issue and in most cases if your device is out of warranty they will ask you to pay for the repair (even tough you didn't do anything that caused a hardware malfunction)

i had a same problem here. Hope apple will repair it at least without charging the owner since its not our fault. I only bought my phone last June 2022. This expensive phone is not worth it at all since i only use it for a year.
