My phone started to have apps crash, some android apps would open then shutdown, and I was having all sorts of crashing and anomalous behavior from Mitakuuluu. I checked the System > About and saw my drive was 12.5GB out of a total 13.7GB
I guessed this lack of space was causing some of the problems.
I moved all my photos and videos and Mitakuuluu/whatsapp files from the main drive to my actual SD card. this saved me 1Gb-ish. I still couldn't find what was taking up so much space though.
@grimtech out of interest, how did you find was the quickest way to copy files to sd card from within the phone? I assume you did it as root in terminal, but is there another way?
@JollaTides I actually did it old skool as I was also putting a new micro SD into my phone. I plugged my Jolla in via USB to my laptop, and put my new card in a usb adapter and plugged that into the laptop too.
Do you (or anyone else for that matter) know of any other ways (other than using terminal) to transfer files from internal storage to SD card from within the phone?
The other methods I've tried are hooking up to Linux PC via USB and also using FTP client to try and move the files between storage, but both those methods won't work due to requiring root.
Otherwise I guess I need to get one of those SD usb readers...
