My Nexus 5 is 6 months old, it hasn't fallen hard, doesn't have a scratch on it, but today the auto-rotate feature was not working. I didn't gave it much thought, but next time I picked up my phone, the whole screen was upside down (see picture attached) and had huge lines all over it, making it very hard to figure out or read anything, and the place were all the buttons should have been were OK, instead of following the change-upside down, so to write a 'A', I have to press 'L' and so on, for everything. Basically impossible to do.

I did a hard reboot to factory settings, and even on the recovery screen everything was upside down, and nothing changed after it.

I have been searching for people with the same issue and I found nearly none or no answers to that thread.
Has anyone experienced the same issue, and what was it in the end?
My phone is under warranty from LG still, but Im afraid if I send it for repair, they will just say is a broken screen, therefore making me pay for it (around 150). If anyone thinks otherwise please say so.

I have found the same issue for other phones (older) and some people say is a broken or faulty Flex Cable. Can this be possible? (I could repair that myself)

Any thoughts on this?

Thanks!
