I have 4000 photos on an SDCard but I guess the indexing will take maybe 24 hours maximum. I might be wrong, just a wild guess. The phone did not pass the day. It came warm out of my pocket, it's cold outside... Sometimes I fired up top in the terminal but it only showed fingerterm and nothing really cpu intesive.

Also, I forgot to mention that apps crashed frequently. The phone app, messaging app and so on. I use to open 6 or 7 apps and when I take my phone out of my pocket, some apps are just greyed out. Something I never had with my X Compact.

That is not of much help unfortunately. The phone will be back on sailfish tonight and I'll post how it works after a few days of usage. This is my main phone.
