My phone updated overnight and now neither my home or overview buttons work anymore - only the back button works out of the three.
This has made my phone virtually unusable since I have to use the back button to get out of whatever app I am in before I can open another - or restart the phone.
I need you to fix this and push an update to me or tell me how to downgrade or otherwise resolve this. I'm due a phone upgrade and after this it doesn't look like I'll be choosing Sony.
My phone:
Sony M4 Aqua (E2303)
Android: 6.0.1
Build: 26.3.A.1.33
