Yes, I have exactly the same problem. 8.90.0 worked perfectly. Did an update to 8.90.1 and "back" button stopped working. This is on an Odroid C2.
I have a similar problem with ir-remote on my X96 - after update to 8.90.1 numeric keys do not work. I went back to 8.90.0, where everything works perfectly.
A microsd card created with "LibreELEC-S905.arm-8.90.6.img.gz" is not being detected as a bootable media by KII Pro.
Device simply boots into Android.
Tried rufus, USB Image Tool, win32diskimager-binary... same result.
Can somebody confirm that?

I have box X96 S905X 2GB/16GB, working with kszaqs 184.108.40.206.
