I thought about that too and I think it's no fault of MSP or Android. 

I sometimes replace PDFs with better scans. I'm doing this on my Windows desktop inside my Dropbox folder which then is synced to my other sheets devices.

So there was a change under Windows. With different devices and different OS to be synced and the different case sensitivities for Windows and Android/Linux I thought it would be sensible to go for case insensitivity in general. (But of course it's never so easy as I think).
