Hello! I'm Jen, and I'd be happy to help you out with this issue.
I have seen similar posts about this and this white screen issue seems to be a hardware design flaw. Have you tried pressing the camera lens directly or around the lens and see if it helps? This might sound simple, but many users having the same issue have reported that this trick worked for them. Let me know if this works for you as well. Thank you.
I hope this information helps. If you have any questions, please let me know and I'll be glad to assist you further.
Best Regards!
Jen :)
